Abstract:
Utilizing medical manuals, medical records, newspapers, and letters, the history of the management of epidemics from 1803-1902 will be explored. This thesis weaves together and explores the political history of the nineteenth century by analyzing the contribution of doctors and reformers in the management of diseases. This thesis explores the intersection between the construction of a public health system and the implementation of these practices by political actors and physicians. The history of the management of disease is analyzed from the introduction of the mass vaccination campaign, in Spain, in 1803. This thesis first analyzes the development of a public health system focused on prevention. It then challenges the system created by examining how effective these measures were against the multiple waves of cholera to hit Spain. It then addresses the important role reformers had in the late nineteenth century. It was through their efforts that doctors and reformers became explicitly linked to new ideas of citizenship and responsibility. This paper emphasizes both continuity in the importance of health care, but also the transformations in the discourse of public health responsibility. Ultimately, it centers liberalism and an emerging middle class within the discussion of a health policy.

Abstract:
The idea of providence was a prominent and pervasive theme in public discourse on subjects of national importance, and upon momentous occasions in nineteenthcentury England. Perceptions of divine involvement and purpose in human affairs embodied in the notion of providence seemed to be at the heart of a religious world view in the Christian tradition, and thus essential elements for study in any historical investigation of religious change. The midcentury years, ostensibly a period of high religious consciousness, provide an opportunity to explore processes which were eventually to lead to the more secular nature of society apparent by the end of the century. The recurring cholera epidemics between 1831 and 1854 were alarming events which provoked reactions throughout society; they provide a means of tracing developments in perceptions of providential involvement in calamitous events during a critical twenty-four year period. Systematic surveys of a broad range of sources, including newspapers, periodicals and sermons were carried out to document the responses of different sections of society, and facilitated investigation of cross-sectional and longitudinal patterns in religious attitudes. It was hypothesised that changing ideas about the nature and extent of providential action in relation to epidemic disease could provide an index of the process of secularization of thought, and thus contribute to the wider debate on secularization. The results vindicated the use of the concept of providence to explore religious consciousness. They have confirmed the mid-nineteenth century to be a critical period for religious change. Analysis of religious perceptions of cholera at three points in time produced a complex picture of changing attitudes, including an unexpected peaking of providential interpretations by some observers during the second epidemic. However, the variation between different sources and social groups did not obscure a significant longer-term trend of decline in providential attitudes, consistent with a secularization of thought during the quarter of a century studied.

Abstract:
The purpose of this essay is to examine the extent to which the cholera epidemics that prevailed in Sweden during the nineteenth century affected Döderhult parish during the period 1834-1866. The study aims first to examine the total number of cholera deaths in Döderhult parish. Additionally, it examines the individuals who died of cholera concerning gender, age and occupation. The essay also aims to examine whether Döderhult parish was more affected by the cholera epidemic than other nearby parishes were and if so, why? In accordance to this, the death rate of Döderhult parish is thus studied in comparison with Mönsterås parish and documented cholera deaths in Fliseryd parish during the period.  The results show that of the 68 people who died in Döderhult parish between 1834 and 1866, 35 were men and 33 were women. The examination of the deceaseds’ age showed that the most vulnerable groups in the parish were the children and the elderly. The results regarding the deceased’s occupation showed that most men, women and children belonged to the working class. Last but not least, the comparative examination between Döderhult parish and the nearby parishes showed that Döderhult parish was worse affected by the cholera epidemic due to factors such as potential trade agreements, overcrowding, lack of public health measures, the industries’ impact on population and the spread of infection through relocation from the town of Döderhultsvik to the parish.

Abstract:
Recent increases in opioid overdose rates have changed the role of first responders on the front lines of this national crisis. The present study used a semi-structured qualitative interview to investigate how the increase in opioids, opioid-related harm, and opioid-related death within Tennessee has affected the first responder population. Law enforcement officers, firefighters, and paramedics (N = 30) from rural-serving counties in Tennessee completed a semi-structured interview. Eight themes emerged from the interviews: (1) mental health symptoms, including posttraumatic stress disorder and secondary traumatic stress symptoms; (2) coping behaviors; (3) available resources; (4) barriers to accessing resources; (5) recommendations for what is needed; (6) hardest circumstances; (7) discrepant thoughts and feelings; (8) perception of role in reducing the impact of the epidemic. This study provides novel insights into the impact of the opioid epidemic on Tennessee first responders, and can inform future efforts to reduce adverse outcomes in these care providers.

Full text
Abstract:
Bloodstream infection (BSI) caused by nontyphoidal serotypes of Salmonella is one of the most important causes of morbidity and mortality in sub-Saharan Africa (SSA). Invasive nontyphoidal Salmonella disease (iNTS) is especially associated with HIV in adults and HIV, malaria and malnutrition in children in this setting. HIV-infected subjects are at particular risk of recurrent disease, both from recrudescence from a sanctuary site and re-infection. Whole- genome sequencing has revealed a novel sequence type (ST) of S. Typhimurium, ST313, is particularly associated with iNTS in SSA and that ST313 display the genomic signature of differential host adaptation. Little is known about African strains of S. Enteritidis. The Malawi Liverpool Wellcome Trust Clinical Research Programme (MLW) has conducted BSI surveillance in adult and paediatric medical patients in Blantyre, Malawi since 1998, enabling long term trends in iNTS to be described. Paediatric iNTS disease has been placed in the context of malaria, malnutrition and seasonality using structural equation modelling. An observational cohort was recruited to describe changes in adult BSI cases following the roll-out of ART in Blantyre. A longitudinal cohort study with enhanced microbiological surveillance was undertaken to investigate the site of persistence of NTS in HIV infected adults and the effect of recurrence upon the emergence of antimicrobial resistance. Lastly whole-genome sequencing was undertaken to compare invasive, African strains of S. Enteritidis with a reference isolate and to construct a global phylogeny of this serotype. There have been three epidemics of invasive Salmonella disease in Blantyre, all of which were preceded by the emergence of a multidrug resistant (MDR) strain. These were caused initially by S. Enteritidis which was then followed by S. Typhimurium, but most recently an epidemic of MDR S. Typhi has started. NTS has declined from epidemic levels, but remains an important cause of BSI in Blantyre and has been demonstrated to acquire cephalosporin iv and fluoroquinolone resistance just once through an IncHI2 plasmid. The decline in paediatric malaria is complex and multi-factorial. It cannot be attributed solely to malaria control interventions as has been the case in other settings. All causes of BSI are falling in adults and this is likely to be attributable in part to the hugely successful HIV treatment programme in Blantyre. The rapid initiation of ART appears to rapidly confer protection against recurrence of iNTS and even though more adult patients are surviving into convalescence, in this cohort, no further emergence of extended resistance was seen. Just as there is a distinct African clade of S. Typhimurium, a distinct clade of S. Enteritidis has emerged in SSA, which also possess the genomic signature of differential host adaptation, a novel prophage repertoire and a novel, MDR plasmid. In Blantyre, iNTS disease has declined from its epidemic peaks, but remains an important cause of BSI. The epidemiology of iNTS is more complex in Blantyre than other settings, but it seems likely that improved in-patient care and measures to control the HIV-pandemic impact on survival and recurrence. Two clades of NTS have emerged from host promiscuous serotypes, both of which have genomic degradation in genes governing potential host range and there is a critical need to understand the environmental niches and transmission pathways of these differentially adapted, invasive clades.

Full text
Abstract:
This comparative case study examining epidemiological practices in Vietnam and the US revealed three pandemic influenza paradoxes: The paradox of attribution which asserts that pandemic influenza comes exclusively from Asia even though historical evidence points to the contrary; the paradox of prevention which encourages industrial methods (i.e., factory farming) for combating influenza even though there is conflicting evidence for any superiority of this method in terms of means of production or disease prevention; and the paradox of action where epidemiologists act in ways not consistent with prevailing epidemiological recommendations.  The existence of these paradoxes may, in fact, impede efforts at stopping and preventing pandemic influenza.  In order to find the root causes of these paradoxes, this study examined indigenous media and historical and contemporary research reports on pandemic influenza.  This archival information was juxtaposed to viewpoints garnered from ethnographic interviews with epidemiologists who have worked in Vietnam, the United States, or in both countries.  This study found that these paradoxes endure because of the dual nature of science " the known and the unknown elements of current knowledge " and assumptions made between the two.  The dual nature of science describes both the information that has been codified and information that has not been codified and the implications between the two. In other words, in between the spaces of known information, there are attempts to fill in the gaps in knowledge, which results in paradoxes. Of particular importance in this gap-filling process are the three "C's" of collaboration, conflict, and competition.  Collaboration is integral to the successful prevention of influenza pandemics; however, it is this same collaboration wherein which epidemiologists are trained to be so highly specialized that they often depend on unvetted external expert information.  Conflict and competition occur from the geopolitical level all they way down to the level of the individual epidemiologist and are influenced by the political and scientific economy along with social and cultural factors.

Abstract:
The present study was conducted to determine the readiness of management at selected manufacturing organisation in the Buffalo City area to manage the HIV/AIDS epidemic. The study was conducted in the Buffalo City area on manufacturing organisations with a workforce greater than 250. The main aims of the present study were: · To provide an overview of relevant literature concerning theoretical key issues related to the management of HIV/AIDS in the workplace. · To assess the readiness of Buffalo City organisations in managing HIV/AIDS in the workplace, and to identify areas of improvement. · In the light of the findings, make further recommendations to manufacturing organisations to further improve their workplace policy, education and awareness programmes; and the accommodation of HIV-infected employees in the workplace. Another objective of the study was to provide additional research as a tool to assist organisations in managing HIV/AIDS in the workplace and to assist in fighting the HIV/AIDS epidemic in the Buffalo City area. The research process entailed: the selection of a test sample of manufacturing organisations in the Buffalo City area, and selecting an appropriate Human Resource manager or representative from these organisations to complete a structured questionnaire. The research tool used in the study was a questionnaire, which was used to extract relevant information on the demographics, policies, education and the accommodation of HIV/AIDS affected and infected employees in the workplace. The results revealed the following: · 73 percent of the selected manufacturing organisations in the Buffalo City have an HIV/AIDS policy in place; · 87 percent of the organisation indicated that their management are committed to the development and implementation of a HIV/AIDS policy; · management and supervisors in these organisations have not been adequately trained to manage the impact of HIV/AIDS in the workplace; · organisations in the Buffalo City area need to collaborate and share information; and · that very few organisations benchmark against best practices. Future research on HIV/AIDS policy can explore the effective implementation of HIV/AIDS policies in these organisations as well as the effective management of HIV/AIDS in the workplace.

Abstract:
The aim of this work is to explore the printed Hawaii shirt through material investigations in search of new print meetings. A vital step for this investigation was to develop the classic Hawaii- prints and motives in mixed media. Followed by exploring alternative printing techniques such as transfer printing, laser cutting and knitting in different materials to reach new expressions yet keeping a clear reference to the Hawaii shirt. The intention of this work was to investigate how the Hawaii shirt with its classic print could interact with the mind and body of the wearer. Furthermore, to question the informal rules of wearing a Hawaii shirt with a starting point in Umberto Eco’s theories about epidemic self-awareness. The motive of this work is to critically look at the society today, with a focus on consumerism, foreign travel and tourism and the expression of it, with the Hawaii shirt as a symbol of these things. Based on the assumption of the Hawaii shirt being a tacky souvenir that tourists bring back home from their holidays. This work show new expressions of the printed Hawaii shirt through innovative print meetings. This work also proposes alternative ways of wearing a Hawaii Shirt.

Abstract:
This study aims to describe the living and informal care circumstances of older people in an area of rural South Africa severely affected by HIV, and examine how those circumstances may influence the physical health, emotional well-being and survival of older people. Using longitudinal surveillance and cross-sectional survey data this thesis is built around four separate but related papers. Specific study objectives were to: 1) investigate household living arrangements and informal care (financial, physical or emotional assistance) by or towards older people in rural South Africa; 2) describe the self-reported health and emotional well-being status of older people by HIV status; and 3) examine the association between self-reported health, emotional well-being and informal care and mortality in older people. Surveillance data for 2005-2010 showed living arrangements remained stable, with over 85% of older people aged 60 years and above living in multi-generational households; over this period employment rates in both older and young people declined, but government grants receipt increased. Being co-resident with own children, household structure and size were important determinants of whether financial support flowed downward (from older to younger) or upward (from young to older person); while peer support (from one older person to another) was rare. Adjusting for age, marital status, education, place of residency and household socio-economic status, exchanges of financial resources in the study population are most likely to be downward or at best reciprocal (bidirectional with young people). Of the cross-sectional study participants (n=422) aged 50+, over 60% were care-givers (provided help with activities of daily living) to at least one adult (18-49 years) or child (below 18 years); around 84% (n=356) of older people were care-receivers; of whom over 92% (n=329) were receiving assistance with fetching water. Spouse, adult child, and grandchildren were the main sources of physical or emotional care for care-recipients. As expected health deteriorated with advancing age and women were less likely to be in good health. Further, care-giving was associated with improved functional ability but decreased emotional well-being. HIV-infected older participants reported better functional ability, quality of life and overall health state than HIV-affected (had an HIV-infected or HIV-related death of adult child) study participants. These differentials in health and well-being were also evident in mortality patterns over three years of follow-up. Mortality was higher among non-care-givers than in care-givers, in older people with poor self-rated health and in participants who had experienced a major depressive episode. Findings suggest there is an intricate relationship between living arrangements, informal care and health, emotional well-being and survival of older people in severely HIV-affected settings. More crucially, with the considerable resources devoted to HIV Care and Treatment programmes, uninfected older persons may be highly vulnerable to poor health. A multifaceted intervention to improving older people’s health and well-being is urgently required.

Abstract:
Background: The cholera epidemic experienced in the province of KwaZulu-¬Natal between August 2000 and July 2001 resulted in 105, 000 reported cases of cholera and 220 human deaths. Objectives: The primary objective of this study was to make comparison between districts with cholera and districts with no cholera in rural KwaZulu-Natal on the basis of known risk factors for cholera and diarrhoeal diseases. Comparison was made with regards to key factors such as the prevalence of diarrhoeal diseases, the provision of safe water supply, ownership and effective utilization of sanitary facilities, knowledge and practice on water purification and prevention of cholera. Methods and materials: This was a descriptive, cross- sectional, ecological and comparative study among households of KwaZulu-Natal. The communities were stratified into two groups. One group had cholera (Group 1) and the other group (Group 2) had no cholera. Thirty communities were selected by systematic random selection from each of the two groups. From each community, eligible households were selected using simple random sampling technique. Trained field workers used a pre-tested questionnaire to collect data during the months of November and December 2001. Statistical procedures such as two-sample tests on means and proportions, Pearson's chi-square tests of association, odds ratios, binary logistic regression analysis, sensitivity tests, specificity tests and ROC (receiver of characteristics) analysis were used for data analysis. Results: A total of 1420 households from both groups were included in the study. The response rate for Group 1 and Group 2 was 84%,92%. Female respondents (70%) predominated male respondents (30%). Tap water supply was less common in Group 1 (54%) than in Group 2 (72%), (p< 0.05). A higher percentage of households in Group 1 (27%) used dam or river water compared to Group 2 (20%) (p<0.05). Household knowledge on water purification by boiling was (71%) in Group 1 and (87%) (p<0.05) in Group 2.38% of households in Group 1 practiced water purification by using disinfectant JIK. The corresponding figure for Group 2 was 50% (p<0.05). Groups 1 and 2 were similar with respect to ownership of toilets (84% and 85% respectively). Groups 1 and 2 showed a marked difference with respect to utilization of toilet facilities by all family members (70% and 89% respectively). The prevalence of diarrhoeal diseases for Group 1 was higher (14.3%) (p<0.05) than the Group 2 was (11.1%). Factors found to be helpful for protection against diarrhoeal diseases were the boiling of water (OR=0.41, 95% CI, 0.19-0.90) and the use of disinfectant JIK (OR=0.45, 95% CI, 0.19-0.94). The study also showed that the use of dam or river water was significantly associated with diarrhoeal diseases (OR=2.92, 95% CI, 1.06-7.80). Conclusion: The results showed that there was significant difference between the two groups of households in regards to basic provision of safe water, knowledge and practice of good hygiene, ownership and effective utilization of sanitary facilities. Findings from this study could be useful as baseline information for future planning, monitoring and evaluation of ongoing programmes.

Abstract:
Cholera in Haiti has persisted since its introduction after the 2010 earthquake. The outbreak demonstrates how a combination of socioeconomic factors, mainly a lack of infrastructure, can cause an outbreak to become a much more serious epidemic and the current enduring endemic. Because cholera came to a previously unexposed nation through United Nations peacekeepers, the outbreak in Haiti offers a unique perspective on the impact of globalization on public health. In addition, it provides a deeper look into the disproportionate impact of diarrheal diseases on low-income countries. Several biological and socioeconomic factors have facilitated the outbreak. Biological risk factors include immunologically naïve populations, low gastric acidity, and blood type. In addition, socioeconomic factors include a lack of clean drinking water and sanitation as well as a fragile and over-taxed healthcare system. The persisting struggle surrounding water and sanitation combined with a lack of knowledge on cholera prevention have precipitated the outbreak into an epidemic and further into its current endemic status. Current efforts to battle cholera include water and sanitation improvements, a national vaccination campaign, as well as the mobilization of community health workers. However, without the construction of sustainable water and sanitation infrastructure, it is unlikely that cholera in Haiti can be eliminated.

Abstract:
In the fall of 1892, fear of cholera was pervasive in North America. Ten years into the fifth international cholera epidemic -- that lasted from 1881 to 1896 -- cholera had been raging in the Middle East, India, and Europe, but the disease had yet to cross the Atlantic Ocean. The maritime traffic of immigrants from Europe was continuous, and each migrant ship potentially carried the disease. Doctors, government officials, and politicians were not asking 'will cholera come?', but rather when. While no one got sick or died of cholera in the city of Toronto in 1892, the crisis and fear of imminent cholera was very real. Drawing on archival research, this dissertation maps how a cholera crisis was shaped by urgency, immediacy, and speculation on the future. My argument will show how the geography of an epidemic is not limited to the presence of a disease. If crises are times of profound activity, how does this event need to be substantiated in order to produce change? This dissertation follows how cholera was integral to producing an object called proliferating life that held together: migrating populations, growing cities, and degeneration; marshland as the source of disease; the medical theory of zymosis that explained how disease outbreaks got out of control; and Malthusian 'laws' of population. Health experts used correlation and synecdoche to visualize these relations. However, these experts needed a stable institutional base to articulate both their fears and their recommendations, which included: professionalized expanding health boards, as social infrastructures; reclaiming Toronto’s marshland of Ashbridge's Bay; and a health ideology built upon the fear of future epidemics, immigration, and a growing economic rationale for health. By the early 20th century, state health became instrumental to a "national vitality", a practice of government intervention that I frame as bureaucratic bio-economy.

Globally, Cholera has been a major infectious disease due to its intercontinental, environmental and cultural factors. This study focused on evaluating the climatic and fresh water proximity factors influencing Cholera epidemic in Cameroon. To this effect, Cholera and climatic datasets in 2004, 2010, 2011 and 2012 to June 2013 were collected and mapped. Both high and low rainfall and temperature extremes were designated as promoters of V. Cholerae development and the highest cases were identified in the Littoral, Extreme North and Centre regions. Spatial autocorrelation using Local (Anselin) Moran I on Cholera cases revealed a cluster of Low-Low positive autocorrelation in Adamawa region in 2004, a High-High cluster of positive autocorrelation in the Littoral region and a Low-High negative autocorrelation in the South region in 2012, a Low-High negative autocorrelation in the South West region and a High-Low negative autocorrelation in the North West in 2013. Furthermore, using population numbers to count Cholera cases (prevalence) from 2010 to June 2013, Local Moran I results show a Low-Low cluster of positive autocorrelation in the South region, a Low-High negative autocorrelation in the North region and a High-Low negative autocorrelation in the Adamawa region in 2010, a High-Low negative spatial autocorrelation in the North region in 2011, a High-Low negative spatial autocorrelation in the South region in 2012 and a High-Low negative spatial autocorrelation in the North region in 2013. Spatial Poisson Regression analysis allowed concluding that Average Temperature, Distance to Streams, Population Distribution and Latitude are statistically significant predictors of increased Cholera cases, whereas Average Rainfall and Longitude are significant predictors of lower Cholera cases.

Rotaviruses (RVs) infection are zoonosis disease that cause acute viral gastroenteritis in young animals and children worldwide. RVs are classified into ten groups (A-J) based on serological assays and nucleotides sequencing of the viral protein 6 (VP6). RVA is considered the most important pathogen in RVs due to the high prevalence and pathogenicity in both humans and a variety of domestic and wild animals. The porcine epidemic diarrhea virus (PEDV) and RVs cause similar clinical sign in piglets, so the pathogens can't be clearly distinguished from gross or histological lesions. As a result, the samples was collected from all ages with clinical sign of diarrhea from Jan 2015 to Dec 2016 to identified the prevalence and co-infections status between RVA, RVB and RVC. The real-time PCR will be used to estimate the percentage of RVA, RVB and RVC, then compare with PEDV at the same time. The results shows that the positive rates of PEDV and RVs (RVA/ RVB/ RVC) are 46.9% and 36.5% (23.2%/ 12%/ 14.9%). RVA, RVB and RVC are 83 (7.7%), 56 (5.2%) and 58 (5.4%) co-infection with PEDV in 1084 samples. There are 23.7% (15.5%/ 6.8%/ 9.5%) that are RVs (RVA/ RVB/ RVC) infection without PEDV. RVs and PEDV have highest prevalence in summer and in spring, respectively. Recent study always focused on RVA and PEDV infections, but RVB and RVC shows high infections in swine population from this study in Taiwan.

This study is firstly discussing education and training for the knowledge on preventing infectious disease and the effectiveness for attitude of cognition. Secondly, to survey the before and after of education and training, we use the questionnaire made by ourselves as a main investigation tool. The subjects are persons in charge with preventing infectious diseases from public and private primary and secondary schools with convenience sampling and screen out 737 effective questionnaires to research. This study shows that after the education and training, achievement rate of students is up to 96.6%. Besides that, campus officers for preventing diseases hold positive attitude about tuberculosis prevention such as caring and managing cases and compatibility of schools, no matter before or after the training. The conclusions of this research proved that the knowledge of campus officers for preventing infectious diseases on diseases prevention can be enhanced through educating and training.
