▼ This dissertation examines knowledge infrastructures for detecting and investigating national outbreaks of foodborne disease. Drawing on archival and ethnographic material from US public health and regulatory agencies, I investigate how officials have built and used surveillance systems to make foodborne outbreaks visible, reflecting the shape of the industrialized food supply. I describe how, in the course of conducting outbreak investigation work, officials confront the challenges of a "balancing act" of needing to be fast but right, facing dilemmas associated with wanting to protect the public health yet minimize economic impact to commercial entities, while grappling with the highly distributed nature of both the food system and a federalist system of public health governance. In the dissertation, I make three core arguments. First, during foodborne outbreak investigations, public health and regulatory officials manage time and uncertainty through systematization. Second, systematization has helped make visible a new kind of public health problem, rooted in the post World War II industrialization of the US food supply-national, diffuse outbreaks caused by contaminated food moving through interstate commerce. Third, despite the importance of and emphasis on systematization in this domain, the numerous and persistent challenges associated with needing to be fast but right preserves a need for expert judgment amidst formal systematization efforts. In addition to examining broader public health infrastructure, the dissertation features analyses of two surveillance systems for foodborne disease: an historical examination of the National Salmonella Surveillance Program from 1962-1976, and an historical and ethnographic study of the current early-warning, real-time system based on molecular subtyping. Through these analyses, I demonstrate how these systems made outbreaks visible not only from a technical perspective, but also from social, political, and economic perspectives as well.

▼ A healthy and balance diet includes consumption of fresh fruits and vegetables. Cucumber (Cucumis sativus) is one of the most cultivated vegetable in the world and is mostly consumed raw. Raw products are recognized as important vehicles for the transmission of human pathogens which causes foodborne illness. According to the Center of Disease Control and Prevention (CDC) Foodborne Outbreak Online Database, there were nine outbreaks due to Salmonella Poona associated with consumption of contaminated food between 1998 and 2008. From July 2015 until February 2016, multistate Salmonella Poona outbreak in the USA was reported due to the consumption of contaminated and imported Californian cucumbers. Hence, measures to decontaminate fresh produce are necessary. Electron-beam irradiation is an effective nonthermal method of decontamination against pathogens such as Salmonella Poona. However, irradiation of fresh produce such as cucumbers could produce negative quality effects such as loss of texture, flavor, and nutrients. Therefore, the process must be characterized. The main objective of this study was to (1) determine the radiation D10-value of Salmonella Poona on sliced cucumber; (2) quantify the effect of electron-beam irradiation on the product quality attributes (texture and color) throughout storage at refrigeration temperature (4-5°C); and (3) optimize irradiation treatment of sliced cucumbers to ensure proper decontamination (5D) while maintaining produce quality. Five (± 2) grams of fresh cucumber was inoculated with 0.5 ml of a 10⁸ CFU/mL of the bacterial culture of Salmonella Poona in sterile bags (18-oz). Samples were irradiated at room temperature with up to 1 kGy with an increment of 0.2 kGy using a low energy electron beam to find the D10-value of the pathogens. Samples were also be irradiated at a 5D dose for decontamination of the pathogen. Irradiated samples were stored at 4-5°C and analyzed for product quality in terms of texture, color, water activity, moisture content, pH, and sensory characteristics for 3 days. All tests were performed in three replications. Non-irradiated samples served as controls. The D10-value of the Salmonella Poona strain used in this study was found 0.38 ± 0.03 kGy. Firmness (texture) of irradiated samples was significantly (P < 0.05) lower than the group of control samples. There was no negative effect (P > 0.05) in the other quality parameters of sliced cucumbers. Therefore, application of an e-beam irradiation decontamination step can significantly improve the microbiological safety of fresh sliced cucumbers.

▼ As the landscape of the diet in the United States changes in response to shifts in consumer preferences and migrating populations, foodborne illnesses remain an important public health challenge. Public health surveillance – the ongoing, systematic collection and analysis of data to prevent and control disease and injury – is the foundation of a prevention-focused food system. As technological advancements simultaneously enhance and disrupt our current surveillance efforts, there is an increasing need to adapt investigation and prevention activities. There is an opportunity to identify novel methods that use existing data to improve surveillance activities. Salmonella – a bacterial foodborne pathogen – is estimated to cause more than one million illnesses per year and is the leading cause of foodborne illness hospitalization. Restaurants are a frequent setting for outbreak and sporadic (non-outbreak) cases of Salmonella infection. Since Salmonella can take advantage of the major pathways for foodborne illness transmission in a restaurant, understanding and controlling its transmission in restaurants is a useful prevention strategy. This dissertation aims to identify opportunities to improve surveillance activities to drive declines in the incidence of foodborne illness using restaurants and Salmonella as a model. The application of novel methods to outbreak investigations and special studies are used to demonstrate an expanded role for surveillance in enhancing food safety. An outbreak of Salmonella infections associated with a chain of quick-service restaurants (Chapter 2) highlights the importance of using all available information in a restaurant-associated outbreak investigation in order to make informed conclusions. An evaluation of restaurant inspection disclosure methods in New York City (Chapter 3) demonstrates the use of surveillance data to evaluate the public health impact of a public disclosure program for restaurant inspections and creates a framework for evaluating future programs. A survey of Minnesota State Fairgoers (Chapter 4) assesses the consumer interest and preferred formats for public disclosure of restaurant inspection results. A second Salmonella outbreak (Chapter 5) explores routine restaurant inspection data to better understand transmission dynamics in a restaurant-associated outbreak, highlighting the value of these data as hazard surveillance. Collectively, the findings from this dissertation demonstrate an important role for linking routine food establishment inspection data with conventional illness surveillance data to improve our food safety systems. These findings will be useful for policymakers, public health officials, and restaurant operators for surveillance-driven prevention of foodborne illness and create a framework for future work in this area.

▼ Elintarvikevälitteiset epidemiat ovat maailmanlaajuinen kansanterveysongelma, etenkin kehittyvissä maissa kuten Vietnamissa. Epidemioiden havaitsemis-ja seurantajärjestelmät sekä valmiudet niiden torjuntaan ja ehkäisyyn ovat näissä maissa puutteellisia: tutkittua näyttöä epidemioiden ja tautitapausten määrästä sekä niiden terveydenhuoltojärjestelmälle ja yhteiskunnalle aiheuttamasta taakasta on vähän. Vietnamissa ilmoitetaan vuosittain virallisesti noin 200 ruokaepidemiaa, 6000 tautitapausta ja 50 kuolemaa. Todellisuudessa nämä luvut ovat huomattavasti suurempia koska puutteellinen seurantajärjestelmä havaitsee vain pienen osan tautitapauksista, laboratorioilla ei ole valmiuksia taudinmääritykseen eikä valtaosaa epidemioiden aiheuttajista kyetä jäljittämään. Vaikka elintarviketurvallisuuden tulisi kattaa koko tuotantoketjun monitoroinnin ja riskikohtien identifioinnin pellolta pöytään, puutteelliset resurssit rajoittavat tämän toteutumista. Väitöskirjatutkimuksen tavoite oli ruokaepidemioiden epidemiologisen seurannan ja torjunnan vahvistaminen elintarviketurvallisuuden parantamiseksi Etelä-Vietnamissa. Tutkimus koostuu neljästä ruokaepidemiasta, joiden selvityksestä päätutkija vastasi toimiessaan Vietnamin Kansanterveyslaitoksessa ja kenttäepidemiologian koulutusohjelmassa. Useat epidemiat liittyivät suurien vientiteollisuusyhtiöiden henkilökunnan joukkoruokaloihin. Hyödyntämällä useita epidemiologisia tutkimusasetelmia näissä tutkimuksissa tunnistettiin laajojen ruokaepidemioiden lähteitä, välittäjäelintarvikkeita sekä riskitekijöitä. Lisäksi tutkittiin elintarviketyöntekijöiden ruokaturvallisuuteen liittyviä tietoja, asenteita ja käytäntöjä. Suurien teollisuuslaitosten ruokaloissa todetuilla epidemioilla on merkittäviä taloudellisia vaikutuksia, mm. sairauspoissaolojen kautta. Tutkimuksen tulokset tuottivat tietoa Etelä-Vietnamin kansanterveysviranomaisille tartuntatautien seurantajärjestelmien kehittämistarpeista, epidemiologisten ja laboratoriovalmiuksien vahvistamistarpeista sekä elintarviketyöntekijöiden koulutuksen sisällöstä. Tutkimuksen kansainväliset yhteistyötahot olivat Vietnamin Kansanterveyslaitos (Institute of Public Health), Ho Chi Minh City ja Maailman terveysjärjestö (WHO), Hanoi, Vietnam sekä Tampereen yliopiston Terveystieteiden yksikkö.; Foodborne diseases (FBD) are a global public health concern. The World Health Organization (WHO) estimates that one billion people in developing countries are affected by FBD annually, resulting in significant economic losses. In Vietnam, approximately 200 foodborne outbreaks, 6,000 cases, and 50 deaths are reported annually. The majority of detected foodborne outbreaks have been linked to large factory canteens in industrial zones manufacturing products for export. Whereas almost all reported fatal cases were associated with family meals. Public health statutory surveillance systems rely on outbreak investigation reports, and most outbreaks are only detected when severe cases are admitted to health facilities or when deaths occur. It is therefore clear that…

▼ After two outbreaks of salmonellosis that were linked to the consumption of almonds in 2001 and 2004, scientific community and industry have encouraged the study of pathogen inactivation kinetics in almonds. However, these studies often have overlooked the increase of water resulting from the inoculation of almonds. This increase of free water may result in data that may be overestimating the final outcome of treatments applied to pasteurize almonds in industrial settings. Therefore, in 2011 a study of almonds was performed at Texas A&M University to determine whether there was a need for Aw restoration. In this study, the effect of accelerated drying on the reduction of Salmonella on almonds was investigated, Salmonella Entritidis PT 30 isolated from one of the outbreaks linked to almonds, and Salmonella Typhimurium LT2 were used. For irradiation, the effect of vacuum packaging and air packaging on the sensitivity of Salmonella to e- beam irradiation was evaluated for both accelerated drying and conventional drying. The D value for Salmonella Entritidis PT 30 when treated with blanching at 88°C with accelerated drying was 10.7± 0.1 s, and 12.8 ± 0.3 s with conventional drying. When subjected to oil roasting at 127˚C, the D values were 10.5 ± 0.1 s with accelerated drying, and 10.2 ± 0.2 s with conventional drying. For irradiation treatments, the D10 value for vacuum packaged almonds was 0.35 ± 0.02 kGy with accelerated drying, and 0.38 ± 0.04 kGy with conventional drying. When irradiated in the presence of air, the D10 value of Salmonella was 0.26±0.04 kGy for almonds with accelerated drying, and 0.29 ± 0.03 kGy conventional drying. In conclusion, the accelerated drying process resulted in greater reduction in Salmonella on almonds in comparison to conventional drying when subjected to blanching but no differences were found for oil roasting (P > 0.05). For e-beam irradiation the D_10 values were significantly greater (P < 0.05) for vacuum with accelerated drying than for Air almonds with accelerated drying. This indicates that if a process applied in the industry were to be developed based on challenge studies when conventional drying was achieved, the almonds might likely be subjected to a treatment that is stronger than necessary to achieve pasteurization.

▼ There are many factors that affect international agricultural trade. One of them is international transportation costs. Another important factor is non-tariff barriers such as sanitary and phytosanitary regulations caused by animal disease outbreaks. The main purpose of this dissertation was to analyze how these factors interfere in the international agricultural trade by examining three cases. In Chapter II, a spatial price equilibrium model of the international cotton sector was utilized to evaluate the effects of the Panama Canal expansion (PCE) on the world cotton industry. Three scenarios were evaluated by reducing ocean freight rates from U.S. Gulf and Atlantic ports to Asian destinations. All scenarios suggested that cotton exports from U.S. Gulf and Atlantic ports would considerably increase. On the other hand, the West Coast ports decreased its participation in total U.S. cotton exports. Overall, total U.S. cotton exports were expected to increase due to the PCE. By using the same model which was used in Chapter II, the third chapter analyzes port improvements in Brazil. By March of 2012, the port of Salvador is expected to have undergone relevant improvements. As a result, the port of Salvador is expected to attract ocean shipping companies which are willing to export directly to Asian importing markets. Scenarios with different reductions in cotton export cost for this port were examined. In general, results indicated a shift in Brazil cotton export flows from the port of Santos to the port of Salvador as well as an increase in exports and producer revenues for the country. Finally, in Chapter IV, the impacts of the 2005 FMD outbreak on the Brazilian meat market was examined. The imposition of an import ban by Russia on Brazilian meat exports was also investigated. By using time series methods, it was found that the outbreak along with the import ban caused a temporary negative price shock to the Brazilian meat market. Export pork and export chicken prices were found to not fully recover after the removal of the import ban by Russia. On the other hand, the export beef price was indicated to undergo a complete recovery. Advisors/Committee Members: Rosson, III, Claude Parr (advisor), Bessler, David A.

▼ In this thesis, I present work conducted as a Master of Philosophy (Applied Epidemiology) (MAE) Scholar based at the OzFoodNet sentinel site at Hunter New England Population Health. During my placement, I was involved in a number of public health investigations both locally and in the Western Pacific region. The MAE core competency requirements and the epidemiological skills that I developed through my field placement are demonstrated in the following chapters. I was fortunate to be at the coalface of public health in my placement at the Local Health District and was able to be involved in a number of outbreak investigations. I led an investigation of an outbreak of Campylobacter in a rural community in New South Wales. This investigation included a retrospective cohort study with the aim of characterising cases and identifying the source of infection to prevent further illness. Data were collected on food and animal exposures prior to the first onset of illness in the community. We found no statistically significant food exposures, however this was complicated by near universal exposure to some food items. A review of cooking processes identified undercooked chicken as the likely source of infection in this outbreak. I was also involved in local outbreaks of gastroenteritis associated with a primary school and a Salmonella Typhimurium outbreak associated with a restaurant. In addition, I was involved in an investigation of paediatric severe acute respiratory infections requiring admission to intensive care units as a part of a World Health Organization deployment to Fiji in May 2016. I conducted an epidemiological project examining environmental risk factors for human infection with Salmonella serovar Wangata in north east New South Wales. I designed and administered a case-control study in three Local Health Districts. Data on environmental exposures were collected for cases and two separate control groups: cases of Salmonella Typhimurium and community controls from the neighbourhood of cases. This project included a large data analysis component, with separate multivariable logistic regression models developed to analyse environmental exposures in each control group. Whole genome sequencing was used to examine the relatedness between human isolates and environmental specimens collected as a part of this project. During my deployment to Fiji in May 2016, I was involved in the surveillance of infectious diseases following Tropical Cyclone Winston. I co-evaluated the Early Warning Alert and Response System (EWARS in a Box) with fellow MAE Scholar, Meru Sheel. Nine syndromes were reported to the EWARS system from 34 sentinel sites in Fiji. The web based EWARS system utilised smartphone reporting and was considered simple, acceptable and generally useful for users.…

▼ The subject of this thesis is the study of a system of multiple simultaneously spreading diseases, or strains of diseases, in a structured host population. The disease spread is modelled using the well-studied SEIR compartmental model; host population structure is imposed through the use of random graphs, in which each host individual is explicitly connected to a predetermined set of other individuals. Two different graph structures are used: Zipf power-law distributed graphs, in which individuals vary greatly in their number of contacts; and Poisson distributed graphs, in which there is very little variation in the number of contacts. Three separate explorations are undertaken. In the first, the extent to which two SEIR processes will overlap due to chance is examined in the case where they do not affect each other's ability to spread. The overlap is found to increase with increased heterogeneity in the number of contacts, all things equal. Introducing differences in infection probability or a delay between introducing the two strains produces more complex dynamics. I then extend the model to allow strains to modify each other's transmissibility. This is found to lead to modest changes in the size of the outbreak of affected strains, and larger effects on the size of the overlap. The extent of the effect is found to depend strongly on the order in which the strains are introduced to the population. Zipf graphs experience somewhat larger reductions in outbreak size and less reduction of overlap size, but overall the two graphs experience similar effects. This is due to the reduced effect of modification in key high-degree vertices in the Zipf graph being offset by higher local clustering. Finally, I introduce recombination and competition by replacement into the model from the first project. The number of recombinant strains that arise is found to be either very low or very high, with chance governing which occurs. Recombinant strains in Zipf distributed graphs have a significant chance of failing to spread, but not in Poisson distributed graphs. Replacement competition in the presence of a growing number of strains is found to both increase the chance of a strain failing to spread, and to reduce the overall size of outbreaks. This effect is equal in both graph types.

▼ Timely monitoring and prediction of the trajectory of seasonal influenza epidemics allows hospitals and medical centers to prepare for, and provide better service to, patients with influenza. The U.S. Outpatient Influenza-like Illness Surveillance Network, or ILINet, collects data on influenza-like illnesses from over 3,300 health care providers, and uses these data to produce indicators of current influenza epidemic severity. ILINet data provide an unbiased estimate of the severity of a season's influenza epidemic, and are typically reported at a lag of about two weeks. Other sources of influenza severity, such as indices calculated from search engine query data from Google, Twitter, and Wikipeida, are provided in near-real time. However, these sources of data are less direct measurements of influenza severity than ILINet indicators, and are likely to suffer from bias. We begin by describing general methods for inference on state space models implemented in the NIMBLE R package, and demonstrate these inferential methods as applied to influenza outbreak forecasting. We then examine model specifications to estimate epidemic severity which incorporate data from both ILINet and other real-time, possibly biased sources. We fit these models using Google Flu Trends data, which uses the number of Google searches for influenza related keywords to calculate an estimate of epidemic severity. We explicitly model the possible bias of the Google Flu Trends data, which allows us to make epidemic severity predictions which take advantage of the recency of Google Flu Trends data and the accuracy of ILINet data, and we preform estimation using Bayesian methods. Models with and without explicit bias modeling are compared to models using only ILINet data, and it is found that including GFT data significantly improves forecasting accuracy of epidemic severity. We also propose hierarchical models which incorporate multiple seasons of influenza data, and evaluate the forecasting benefits that hierarchical modeling confers.

▼ [EN] Legionella pneumophila is a strictly environmental and opportunistic pathogen that can cause severe pneumonia after inhalation of aerosols with enough bacterial load. Outbreaks and sporadic cases are usually localized in temperate environments, and the reservoirs are often water-related sources where biofilms are created. The existence of non-cultivable forms of the bacteria increases the risk for public health, as culture-based methods may miss them, thus complicating the environmental investigations of the sources. Genetic classification through the Sequence-Based Typing (SBT) technique allowed an increased discrimination among L. pneumophila strains compared to previous methods. SBT data can also be used for genetic variability and population structure studies, but a more exhaustive analysis can be performed using high-throughput genome sequencing strategies. This thesis describes the use of both SBT and genomic sequencing to evaluate and provide solutions to different public health needs in L. pneumophila epidemiology. We have focused in the Comunidad Valenciana (CV), the second region in Spain with the highest incidence of Legionellosis, with special interest in the city of Alcoy, where recurrent outbreaks have occurred since 1998. Firstly, SBT data were used to gain a deeper insight into the genetic variability and distribution of the most abundant Sequence Types (ST) in the CV area. We have shown that the level of variability in this region is comparable to that from other countries, revealing the existence of both locally and broadly extended profiles. Approximately half of the observed genetic diversity was found to result from geographical and temporal structure. Secondly, L. pneumophila detection from environmental sources remains a challenge for public health. A comparison between water and biofilm samples using a sensitive touchdown PCR (TD-PCR) strategy revealed that the use of biofilms increased by ten-fold the detection rate. This method allowed evaluating the hidden uncultivable L. pneumophila diversity in the locality of Alcoy and the real-time investigation of a Legionellosis outbreak affecting a hotel in Calpe (Southeast of Spain) in 2012. Thirdly, genomic sequencing was applied to a set of 69 strains isolated during 13 outbreaks occurred in Alcoy in the period 1999-2010, mainly the recurrent ST578. Higher intra-outbreak variability than expected was observed, pointing to the potential existence of multiple sources in this endemic area or high environmental diversity. Interestingly, above 98% of the genomic variability in this ST was found as being incorporated through recombination processes rather than through point mutations. Finally, a metagenomic analysis of environmental biofilms from Alcoy revealed a microbial community dominated by Proteobacteria, Cyanobacteria, Actinobacteria and Bacteroidetes. Despite the known endemism of Legionella in this area, the genus was only found in a relative abundance ranging 0.01-0.07%, which explains the low recovery from environmental sources. … Advisors/Committee Members: González Candelas, Fernando (advisor).

▼ The influenza virus is responsible for significant morbidity and mortality worldwide each year, with influenza pandemics occurring every 10 to 50 years and responsible for millions of deaths and substantial economic impact. Increasing globalisation through travel and trade means New Zealand is vulnerable to the risks of pandemic influenza, placing a strain on the healthcare system, putting lives at risk and posing a significant cost to the country. Emergency Departments are at the frontline of New Zealand’s healthcare system and are a crucial component in the response to an influenza pandemic, however little research has been done on the impact such an event would have on the nursing staff who work in this area and the care they provide to influenza patients. This study aims to explore what New Zealand Emergency Department nurses perceive as the biggest challenges to nursing care and staff safety during an influenza pandemic, in order to provide information on how to ensure the engagement of these nurses at the frontline of the pandemic response. With a lack of evidence-based research available, a qualitative descriptive design was used to allow an exploration of the first-hand perspectives of Emergency Department nurses, gaining meaningful insights into a phenomena which has been little explored. Sixteen nurses from two Emergency Departments participated in face-to-face interviews conducted using semi-structured questions. Raw data was transcribed, and an inductive approach was taken to data analysis, guided by the principles of both content and thematic analysis. The findings demonstrate that Emergency Department nurses work in an environment that poses risk to patient and staff safety every day, and an understanding of these safety problems is provided in the theme ‘the everyday reality for Emergency Department nurses’. Working within this context shapes the fears that Emergency Department nurses hold about what could happen if an influenza pandemic were to affect New Zealand in the future, and are summarised within the theme ‘fears for a pandemic’. The final theme, ‘strategy and planning for pandemics’ provides insight into how Emergency Department nurses feel these issues could be managed within future pandemic planning at Emergency Department, District Health Board and government level. This thesis identifies both existing and potential future safety concerns in relation to the management of influenza in New Zealand Emergency Departments, affecting the safety of patients and staff. It also provides specific multi-level and multi-agency recommendations for future pandemic plans that could help to mitigate the significant risks highlighted by those who work within the system every day.

▼ This work explores the climatologies of isolated tornadoes and tornado outbreaks across the state of Tennessee, a state that in some years experiences more tornadoes than states in the heart of Tornado Alley. Part one assesses tornado frequency characteristics and fatality statistics within 100 km of three major Tennessee cities (Nashville, Memphis, and Knoxville) between 1950 and 2013. Nashville reported the most tornadoes, (426) but Memphis reported the most fatalities. Knoxville and Nashville tornadoes occurred on fewer days, while Memphis tornadoes were spread across more tornado days. Spring was the most active season for tornadoes, but Memphis still experienced approximately 25% of its total tornadoes in the winter, a season prone to nocturnal tornadoes. There was no statistically significant difference between the seasonality of tornadoes for each of the cities, which is surprising given the longitudinal expanse of the state. Regional-scale analyses of this type provide insight on how tornado risk and vulnerability may vary considerably across a single state. Part two analyzes tornado outbreak characteristics (1980–2014) from a climatological perspective and assesses how a large-scale climate oscillation may affect tornado and tornado-outbreak frequencies across Tennessee. Results indicate that 72.5% of all tornadoes in Tennessee occur in outbreaks, when an outbreak is subjectively defined as any 24-hour period with four or more tornadoes within the state. Winter, defined as Dec/Jan/Feb, had the second-highest tornado-outbreak frequency. This provides a possible explanation for the high frequency of tornado-related fatalities in Tennessee, as the winter is a time of reduced daylight and is when nocturnal tornadoes, which are twice as likely to kill, are most prevalent. The Multivariate ENSO Index (MEI) was investigated using generalized linear models with a Quasi-Poisson distribution to determine if a relationship existed between tornado activity and a large-scale climate oscillation. Results indicate that above (below) average values of MEI, or El Niño (La Niña) events, are related to times of decreased (increased) tornado activity across Tennessee, and are supported by meteorological considerations. Offering future estimations of tornado activity on a seasonal or monthly scale can aid in reducing susceptibility to these dangerous events. Advisors/Committee Members: Kelsey N. Ellis, Sally P. Horn, Nicholas N. Nagle.

▼ Influenza is a disease which affects millions of people every year and causes hundreds of thousends of deads every year. This disease causes substantial direct and indirect costs every year. The influenza epidemic have a particular behavior which shapes the statistical methods for their detection. Seasonal epidemics happen virtually every year in the temperate parts of the globe during the cold months and extend throughout whole regions, countries and even continents. Besides the seasonal epidemics, some nonseasonal epidemics can be observed at unexpected times, usually caused by strains which jump the barrier between animals and humans, as happened with the well known Swine Flu epidemic, which caused great alarm in 2009. Several statistical methods have been proposed for the detection of outbreaks of diseases and, in particular, for influenza outbreaks. A reduced version of the review present in this thesis has been published in REVSTAT-Statistical Journal by Amorós et al. in 2015. An interesting tool for the modeling of statistical methods for the detection of influenza outbreaks is the use of Markov switching models, where latent variables are paired with the observations, indicating the epidemic or endemic phase. Two different models are applied to the data according to the value of the latent variable. The latent variables are temporally linked through a Markov chain. The observations are also conditionally dependent on their temporal or spatio-temporal neighbors. Models using this tool can offer a probability of being in epidemic as an outcome instead of just a ‘yes’ or ‘no’. Bayesian paradigm offers an interesting framework where the outcomes can be interpreted as probability distributions. Also, inference can be done over complex hierarchical models, as usually the Markov switching models are. This research offer two extensions of the model proposed by Martinez-Beneito et al. in 2008, published in Statistics in Medicine. The first proposal is a framework of Poison Markov switching models over the counts. This proposal has been published in Statistical Methods in Medical Research by Conesa et al. in 2015. In this proposal, the counts are modeled through a Poisson distribution, and the mean of these counts is related to the rates through the population. Then, the rates are modeled through a Normal distribution. The the mean and variance of the rates depend on whether we are in the epidemic or nonepidemic phase for each week. The latent variables which determine the epidemic phase are modeled through a hidden Markov chain. The mean and the variance on the epidemic phase is considered to be larger than the ones on the endemic phase. Different degrees of temporal dependency of the mean of the data can be defined. A first option is be to consider the rates conditionally independent. A second option is to consider that every observation is conditionally dependent on the previous observation through an autoregressive process of order 1. Higher orders of dependency can be defined, but we limited… Advisors/Committee Members: Martínez Beneito, Miguel Ángel (advisor).

▼ In this dissertation, I focused on the role of plant hosts as a driving force leading to phenotypic and genotypic changes in insect herbivores. There are three main questions addressed: (1) Do generalist species' populations have broad diet breadth or do they represent a mosaic of sub-populations, each having narrow diet breadths? (2) How do host plants affect the immune response of polyphagous herbivores? and (3) Do host plants or host plant such as allelochemicals, alter the interaction between herbivore defense and parasitoid counter-defense? Do generalist species' populations have broad diet breadth or do they represent a mosaic of sub-populations each having narrow diet breadths? In Chapter 1, I determined, using amplified fragment length polymorphisms (AFLPs), whether host plant-associated genetic differentiation (HAD) was exhibited by a suite of polyphagous tree feeding macrolepidoptera. I determined this by using polyphagous species that exhibit traits expected to be important in the formation of genetically divergent sub-populations. How does host plant affect the immune response of polyphagous species? In Chapter 2, the objective was to examine the effect of host plant species on the immune defenses of polyphagous lepidopteran herbivores, specifically the intensity of encapsulation measured as percent melanization, of three common forest Lepidoptera species. In Chapter 3, I discuss and assessed the potential role of immune responses in insect outbreaks. I present a brief background on immune responses, discuss the methods used to experimentally measure the components associated with immune response and how immune response varies. Lastly, I draw on the studies available and present several potential hypotheses to stimulate further research. Does host plant, or some aspect of host plant such as allelochemicals, alter the interaction between herbivore and parasitoid? In the final chapter, I explored the ecological consequences of viral-plant allelochemical interactions. The objective of this study was to use a model system, Manduca sexta and Cotesia congregata, to directly test the effect of the allelochemical nicotine and the presence or absence of polydnavirus (PDV) on larval immune responses. PDV allows the parasitoid egg to escape encapsulation (an herbivore defense against parasitism). Advisors/Committee Members: Barbosa, Pedro (advisor).

▼ Multistate outbreaks of salmonellosis associated with consumption of fresh cantaloupes from salad bars suggest that contamination occurred early in the farm to fork chain, rather than immediately before consumption. Factors that may influence the adherence, survival, and growth of Salmonella enterica serotype Poona on and in cantaloupes were investigated. The effects of temperature differentials between cantaloupes and S. Poona suspensions at 4°C and 30°C, on changes in fruit weight and populations of the pathogen recovered from rinds and stem scar tissues of Eastern and Western type cantaloupes were assessed. The weight of immersed cantaloupes increased by 0.13 – 0.43%, with Western cantaloupes showing greater increases. Initial temperature of the inoculum and cantaloupe affected weight increase by Eastern cantaloupes, but not Western type cantaloupes. The histology of cantaloupe rind and stem scar tissues augments attachment and penetration by contaminating S. Poona, potentially reducing effectiveness of sanitizer treatments. Proteolytic activity and changes in pH of cantaloupe rind caused by growth of the phytopathogens Alternaria alternata, Cladosporium cladosporioides, Epicoccum nigrum, Geotrichum candidum, and Penicillium expansum were studied. Survival and growth characteristics of S. Poona on the surface rind and in wounded tissue as affected by co-infection with molds and storage at 4°C and 20°C for up to 21 days were determined. Populations of S. Poona on intact and wounded rind tissues at 4°C decreased by 1 – 2 logs, but increased by 3 – 6 logs at 20°C. Co-infection with molds did not affect populations of S. Poona recovered from cantaloupe rinds. The pathogen migrated from wounded tissues in the rind through pulp tissues to distances as great as 3 – 4 cm below the surface, with or without coinfection with phytopathogens. Migration and survival of S. Poona in cantaloupes were enhanced by co-inoculation with C. cladosporioides and, to a lesser extent, P. expansum. Ten yeasts were screened for antagonistic activity against S. Poona in cantaloupe juice and decay by C. cladosporioides and G. candidum, in wounds on the surface of cantaloupe rind. Some of the yeasts demonstrated their potential to restrict colonization of wounded tissues by phytopathogenic molds, particularly at low storage temperatures. Test yeasts did not markedly restrict growth of S. Poona in cantaloupe juice.

▼ In South Dakota, grasshoppers (Orthoptera: Acrididae) are sporadic pests that can cause economic injury to rangeland and crops during outbreaks. It is important to know which grasshopper species are present as not all have the same potential to cause damage. USDA-APHIS conducts annual grasshopper surveys in western South Dakota rangelands, but the last published survey was in 1925. Of the potential biological control agents existing, grasshopper mites feed on grasshopper eggs and the larvae are ectoparasites of nymph and adult grasshoppers. Previous studies suggest that mite larvae reduce grasshopper fecundity and mobility, making them useful for integrated pest management of grasshopper populations. Yet, a study evaluating grasshopper mites in South Dakota has not been conducted since 1944. The purpose of the first study was to determine the abundance and species diversity of grasshoppers and the second study was to determine the density and distribution of grasshopper mites in South Dakota. Data for both studies was obtained by sampling grasshoppers in both 2017 and 2018 using sweep nets with 40 pendulum sweeps. Samples from western South Dakota were collected in rangeland and donated by USDA-APHIS. For eastern South Dakota, 400 sites were sampled once with two samples collected simultaneously from ditches alongside crop and rangeland. The first study determined that the most abundant species were Melanoplus femurrubrum and Phoetaliotes nebrascensis. For both years, a majority of grasshopper populations did not exceed the recommended thresholds; however, there were localized “hot spots” that greatly exceeded the thresholds. Results of the second study indicated that the most abundant mite (i.e., over 90%) was Eutrombidium spp., which was most commonly found on M. femurrubrum nymphs. For both years, the majority of mite populations were relatively low or absent. However, there were localized, increased populations that were related to increased grasshopper populations. The results from the first study suggest that annual grasshopper surveys are necessary to detect potential outbreaks and forecast “hot spots” in the future, while the results from the second study suggest that annual grasshopper mite surveys could improve the overall understanding of the importance and impact that grasshopper mites could serve for integrated pest management purposes.

▼ Pilaantuneen juomaveden aiheuttamat epidemiat ovat kehittyneissä maissa vähentyneet järjestäytyneen vesi- ja jätevesihuollon myötä. Tästä huolimatta myös näissä maissa epidemioita edelleen esiintyy. Suurissa taajamissa tuhannet asukkaat voivat saada juomavetensä saman jakeluverkoston kautta. Jos veteen pääsee taudinaiheuttajia, seurauksena saattaa olla hyvinkin laaja epidemia. Suomessa rekisteröitiin yli 70 juomaveden aiheuttamaa epidemiaa vuosina 1997-2009, suurimmissa näistä sairastuneita arvioitiin olleen tuhansia. Juomavesivälitteisissä epidemioissa sairastutaan yleensä vatsatautiin, joka tavallisimmin paranee itsestään. Osa sairastuneista saattaa kuitenkin saada jälkioireita jotka voivat aiheuttaa oireita kuukausien ajan. Toisinaan vesiepidemioihin on liittynyt myös kuolleisuutta. Nokian kaupungissa Pirkanmaalla koettiin loppuvuonna 2007 maamme oloissa poikkeuksellisen laaja pilaantuneen juomaveden aiheuttama epidemia. Erehdyksessä auki jääneen venttiilin kautta talousveden joukkoon pääsi sekoittumaan huomattava määrä mikrobirikasta, käsiteltyä jätevettä. Talousvesi pilaantui pahoin kaupungin eteläisessä osassa, jossa asui n. kolmannes kaupungin väestöstä. Tämä tutkimus pohjautuu Nokian epidemian terveysvaikutusten selvitystyöhön, joka käynnistettiin Terveyden ja hyvinvoinnin laitoksen, Tampereen yliopistollisen sairaalan (TAYS), Tampereen yliopiston ja Nokian kaupungin yhteistyönä pian epidemian alettua. Tutkimuksen tarkoituksena oli selvittää epidemian laajuus (vatsatautiin sairastuneiden määrä ja osuus väestöstä), mikrobiologiset löydökset ja niveloireiden esiintyvyys. Lisäksi selvitettiin vatsa- ja niveloireiden kestoa vatsatautiin sairastuneilla sekä epidemian aiheuttamia suoria terveystaloudellisia kustannuksia. Tutkimus toteutettiin käyttämällä väestökyselyä, jota varten Nokian kaupunki jaettiin kahteen alueeseen, pilaantuneen ja puhtaan veden alueisiin. Kontrolliväestöksi valittiin Kangasalan kunnan asukkaat. Kultakin alueelta muodostettiin tuhannen asukkaan otokset. Toinen kyselytutkimus, seurantatutkimus, toteutettiin 15 kk epidemian alusta. Kyselytutkimusten lisäksi aineistoa kerättiin TAYS:n ja Nokian terveyskeskuksen tietokannoista. Yli puolet (53 %) pilaantuneen veden alueen asukkaista sairastui vatsatautiin. Vatsatautitapausten ylimäärän tällä alueella arvioitiin olleen 4519 vertailtaessa ilmaantuvuuteen kontrolliväestössä. Myös Nokian puhtaan veden alueella todettiin ylisairastuvuutta. Ulostenäytteissä todettiin seitsemän taudinaiheuttajaa joista kuusi osoitettiin myös talousvedestä otetuista näytteistä. Tärkeimmät taudinaiheuttajat olivat kampylobakteerit, norovirus ja Giardia lamblia. Pilaantuneen veden alueen asukkaista 13,9 % koki niveloireita ja 6,7 % niveltulehdukseen viittaavia oireita vatsataudin jälkeen. Niveloireiden todennäköisyys havaittiin kontrolliväestöä korkeammaksi myös niillä asukkailla, jotka eivät sairastuneet vatsatautiin. Tämä saattaa selittyä oireettomilla tartunnoilla, jotka kuitenkin ovat laukaisseet niveloireita. Seurantatutkimuksen perusteella 43 %:lla…

A Leucose Enzoótica dos Bovinos (LEB) é uma ameaça à saúde dos rebanhos bovinos do estado de Pernambuco e o aperfeiçoamento no uso de ferramentas epidemiológicas para identificação e eliminação de focos desta doença demanda atenção. O objetivo com a realização deste estudo foi avaliar a leucometria como um recurso auxiliar para a identificação de focos da LEB e saneamento dos rebanhos, a partir de ensaios realizados para estabelecer a prevalência dessa insidiosa retrovirose e da Tuberculose Bovina (TB) em rebanhos criados em vários municípios do estado. Foram submetidas ao sorodiagnóstico para LEB amostras de 1.000 bovinos procedentes de 33 rebanhos, sendo 920 deles submetidos previamente ao teste da tuberculina (TCC). Em aproximadamente 70% (694/1000) dos bovinos foram realizadas análises leucométricas, sendo desconsiderados das mesmas os animais com resultados inconclusivos aos dois testes diagnósticos e os positivos ao teste da tuberculina. Desta forma, 530 amostras foram distribuídas em dois grupos experimentais, em função dos resultados à IDGA: GI = leucogramas de 379 bovinos soronegativos; e GII = leucogramas de 151 bovinos soropositivos. As prevalências da LEB e TB foram 28% (282/1000) e 11% (99/920), respectivamente. Globalmente, os valores médios dos leucócitos foram: totais = 12,0 4,7 e linfócitos = 8,1 5,4 (x103/mm3). Considerando os grupos experimentais, os valores médios dos leucócitos do GI (totais = 11,5 3,8 e linfócitos = 7,6 5,1 x103/mm3) foram significativamente menores (p<0,05) do que os do GII (totais = 13,3 6,3 e linfócitos = 9,1 5,9 x103/mm3). Dentre os bovinos examinados 30% (159/530) apresentaram leucocitose por linfocitose LL (leucócitos totais e linfócitos maiores do que 12,1 e 8,4 x103/mm3, respectivamente), tendo o GI maior frequência de animais (99/379) com esta disfunção linfoproliferativa do que o GII (60/151), contudo os valores leucométricos médios do GII (totais = 18,6 6,5 e linfócitos = 14,0 6,7 x103/mm3) foram significativamente superiores (p<0,05) aos do GI (totais = 15,9 3,1 e linfócitos = 12,1 8,0 x103/mm3). Analisando os bovinos portadores de LL e que apresentaram os valores leucométricos acima do limite tolerável de referência (totais = 15,0 e linfócitos = 12,7 x103/mm3, respectivamente), não foi observada diferença significativa entre os grupos GI (totais = 19,9 3,5 e linfócitos = 15,8 3,9 x103/mm3) e GII (totais = 23,2 7,4 e linfócitos = 19,2 7,4 x103/mm3). Bovinos do GI (soronegativos) portadores de LL (totais >15,0 e linfócitos >12,7 x103/mm3) foram considerados suspeitos, pois não apresentaram diferença leucométrica significativa com os do GII (soropositivos) portadores de LL. Conclui-se que, com a demonstração da interferência do VLB no leucograma dos bovinos examinados e com a identificação de bovinos suspeitos não detectados pela IDGA, a leucometria se presta como recurso auxiliar para a identificação de focos da LEB e saneamento dos rebanhos.

A Leucose Enzoótica dos Bovinos (LEB) é uma ameaça à saúde dos rebanhos bovinos do estado de Pernambuco e o aperfeiçoamento no uso de ferramentas epidemiológicas para identificação e eliminação de focos desta doença demanda atenção.

▼ Influenza A viruses have caused several devastating outbreaks in poultry with some zoonotic infections and deaths in humans. To control the viruses and their continuous circulation in poultry population, an understanding of the epidemiology of the viruses is needed. An evaluation of the situation of avian influenza A H5N1 in two African countries most affected by this virus was conducted. To that end, two aims were pursued: (i) to identify the factors that played important roles in the dissemination and circulation of the virus, and (ii) to explore the potentials of the virus from becoming endemic in the poultry populations in Africa. The analyses partly described the extent of H5N1outbreaks in Nigeria in at-risk and non-infected premises and live bird markets in the country. All samples (tracheal and cloacal swabs, parenchymatous tissues and sera) were analysed using virus isolation, reverse-transcription polymerase chain reaction and serology. Primary data on influenza A H5N1 in human as recorded by the Egyptian government was collected and analysed using different variables and risk factors for HPAI H5N1 virus infection in poultry farms in Nigeria during 2006-2007 outbreaks in Nigeria were explored using the conditional logistic regression models. Factors that supported infections in new premises included: receiving visitors on farm premises, purchase of live poultry/products, farm workers that live outside the premises. Because biosecurity is important to reduce risks of infection in poultry farms, the effects and costs associated with the implementation or neglect of biosecurity, as well as the feasibility of implementation in the household poultry in Egypt were evaluated. Risks of particular importance for the household poultry were categorised into people-related, environmental-related and other birds/animal-related risks. Biosecurity measures were compatible in the household poultry and it is 8.45 times better to implement biosecurity than to do nothing against HPAI H5N1. The financial risk analysis was robust and withstood sensitivity analysis. The change that may occur in the course of the household poultry project was accommodated profitably. The effect of road network and its contributions to the epidemics in Nigeria were evaluated to determine whether HPAI H5N1 exhibit properties of network theory. Spatial aggregation of cases (disease clusters), links among similar ‘nodes’ (assortativity), simultaneous activation of similar nodes (synchronicity), epidemic flows moving from highly to poorly connected nodes (directionality), and a Pareto analyses pattern were observed including synchronicity and directionality of spread properties. An exploratory analysis was conducted on the probability of human infection through the oral contacts with A-H5N1 contaminated meat. Detailed quantitative risk assessment using predictive microbiology-process risk model revealed that up to 15,159 humans may have contracted HPAI H5N1 in Africa, with 1,964 deaths. These figures are higher than those officially reported. The model… Advisors/Committee Members: Stegeman, Arjan, Rivas, A.L..

▼ Thesis title: Dynamics and organisation of precipitation bands in the midlatitudes.Submitted by Jesse Norris to The University of Manchester for the degree of Doctorof Philosophy (PhD). 24 March 2014.This thesis was funded by the Natural Environmental Research Council (NERC)as part of the Diabatic Influences on Mesoscale Structures in Extratropical Storms(DIAMET) project. The thesis is presented in alternative format, meaning that theresults of the thesis take the form of three journal articles, each telling a distinctstory within the subject matter, but collectively highlighting the sensitivity of bandsto frictional and diabatic processes.Paper 1 is an idealised-modelling study with the Weather Research and Fore-casting (WRF) model, in which moist baroclinic waves are simulated from an initialzonally uniform midlatitude jet on an f -plane at 20-km grid spacing, and the sen-sitivity of the resulting precipitation bands is explored. Paper 2 employs furtherWRF idealised-baroclinic-wave simulations and takes a simulation from Paper 1,after the cold front has formed, as the initial condition. A nested domain at 4-kmgrid spacing is inserted when this simulation is re-initialised to invesigate the sensi-tivity of finer-scale precipitation cores along the surface cold front. In both Papers 1and 2, friction and latent-heat release enhance multiple banding at the two distincthorizontal scales, while surface fluxes hinder multiple banding.Paper 3 studies postfrontal snowbands over the English Channel and Irish Seaduring extreme cold-air outbreaks in the winters of 2009–10 and 2010–11, via a cli-matology of precipitation-radar, sounding, and SST data, and real-data WRF sensi-tivity simulations of one such band over the English Channel. The observational andmodelling results show that strong winds and large differential heat fluxes betweenland and sea were necessary to generate banded precipitation. Coastal orographyand the land–sea frictional contrast aided the morphology of bands, but bandedprecipitation did still form in the absence of these influences in the sensitivity sim-ulations.These three studies and the thesis as a whole highlight the role of frictional anddiabatic processes in modifying various types of precipitation bands within baroclinicwaves, and in generating bands that would otherwise not exist.

Les maladies infectieuses posent un problème majeur de santé publique à travers le monde. En effet, les maladies infectieuses étaient la cause en 2004 de près de 15 millions de décès, que ce soit pour des pathogènes émergents, des pathogènes connus de l’homme depuis de nombreuses années ou encore des pathogènes ré-émergents (Estimation 2004 de l’OMS). Ce nombre a diminué. Cette évolution à la baisse touche la plupart des maladies infectieuses, mais une augmentation reste du domaine du possible comme l’a démontré la récente épidémie d’Ebola. Pour lutter contre ces maladies infectieuses, de nombreux outils de surveillance épidémiologique ont vu le jour à travers le monde. Ces systèmes ont pour but de détecter et d’identifier le plus précocement possible des évènements épidémiques favorisant l’alerte auprès des autorités compétentes et la mise en place de contre-mesures. L’objectif de notre travail a été de construire et de développer un système de surveillance épidémiologique à partir des données de laboratoire de microbiologie de la région Provence-Alpes Côte d’Azur (PACA). Ce système doit nous permettre d’identifier de possibles évènements anormaux de façon hebdomadaire à partir des données des différents laboratoires participants. Le système de surveillance nous a par la suite permis de déclarer plusieurs alertes auprès de l’Agence Régionale de Santé (ARS) PACA, de valoriser notre travail par des publications et enfin de valoriser le travail des laboratoires en leur transmettant une rétro-information contenant les principales alarmes de la semaine.

Infectious diseases are a major public health problem worldwide. Indeed, infectious diseases were the cause in 2004 to nearly 15 million deaths, whether for emerging pathogens, pathogens known to man for many years or even re-emerging pathogens (2004 Estimation of WHO). It has fallen since we moved, for example, 1.27 million cases of malaria in 2004 to 854,600 in 2013. This downward trend affecting most infectious diseases, but an increase is still the realm of possibility as the demonstrated by the recent outbreak of Ebola.To fight against these infectious diseases, many epidemiological surveillance tools have emerged worldwide. These systems are designed to detect and identify as early as possible of possible epidemic events to promote the warning to the competent authorities and the establishment of counter-measures. The objective of our work was to build and develop an epidemiological surveillance system from the microbiology laboratory data of the Provence-Alpes Côte d'Azur (PACA). This system should enable us to identify possible abnormal events weekly data from the different participating laboratories. The monitoring system has enabled us later to declare several warnings from the Regional Health Agency (ARS) PACA, enhance our work through publications and finally to promote the work of laboratories by providing them a feedback containing the main alarms of the week.The development and automation of the system through the creation of an IT platform developed…
