Thesis (MPH.) --University of Limpopo, 2016 / Background: Malaria is one of the important communicable diseases transmitted by Anopheline mosquitos to humans and is endemic in 108 countries around the world. Most malaria epidemics in African highland countries are caused by Plasmodium Falciparum (P Falciparum) and people residing in highlands are said to be having low immunity to malaria and both children and adults are affected by the disease, whereas vivax malaria is common in lowlands African countries. The current study was undertaken with an aim to determine the spatial distribution of malarial cases during the period 2006 to 2015 in Mopani District of Limpopo Province, South Africa. Methods: Quantitative retrospective descriptive methodology was employed to review the malaria distribution in Mopani district. A total of 12 037 malaria cases were identified for the period of the study and the data was kept anonymously by not using the names of the patients. Ethical clearance was received from the Turfloop Research Committee of University of Limpopo in consideration of section 14, 15, 16, and 17 of National Health Act 61 of 2004. The data was exported to excel spreadsheet and cleaned before exported into SPSS 23.0 software which was used for data analysis. Results: The findings revealed that most malaria cases were found in 2006 and again in 2014 and 2015 respectively. Malaria cases were also seen to be seasonal and were very high during January, February, March and April. Malaria cases also hiked during the month of October. The results also show that most malaria cases were reported between the patients aged of 16 to 25 and 26 to 40 years. There were more males than females who were infected by malaria in Mopani district and the sub district which was found to be having high malaria cases is Greater Giyani with more than 50% of the population (51.1%); followed by Ba Phalaborwa (23.1%); then Greater Tzaneen 13.1%. Conclusion: Mopani district has halved its malaria transmission for the comparison years, however the slow reduction in numbers of deaths is still a cause for concern. Key words: Malaria prevalence, spatial distribution, case fatality rate, elimination.

Background Malaria remains a serious epidemic threat in the Lowveld region of Mpumalanga Province. In order to appropriately target interventions to achieve substantial reductions in malaria morbidity and mortality, there is a need to assess the impact of current control interventions such as indoor residual spraying (IRS) for vector control. This study aimed to assess long-term changes in the burden of malaria in Mpumalanga Province during the past eight years (2001-2009) and whether IRS and climate variability had an effect on these changes. Methods All malaria cases and deaths notified to the Malaria Control Programme, Department of Health was reviewed for the period 2001 to 2009. Data were retrieved from the provincial Integrated Malaria Information System (IMIS) database. Climate and population data were obtained from the South Africa Weather Service and Statistics South Africa, respectively. Descriptive statistics were computed to determine any temporal changes in malaria morbidity and mortality. Autoregressive integrated moving average (ARIMA) models were developed to assess the effect of climatic factors on malaria. Results Within the eight-year period of the study, a total of 35,191 cases and 164 deaths-attributed to malaria were notified in Mpumalanga Province. There was a significant decrease in the incidence of malaria in Mpumalanga Province from 385 in 2001/02 to 50 cases per 100,000 population in 2008/09 (P < 0.005). The overall incidence and case fatality rates were 134 cases per 100,000 and 0.54%, respectively. Malaria incidence and case fatality rate by gender showed significant differences, higher in males than in L.M. Ngomane University of Pretoria, 2012 iv females (166.9 versus 106.4; P < 0.001; CFR 0.41% versus 0.55%). The incidence of malaria increased from age 5-14 years (70), reaching a peak at age 25-34 years (190), declining thereafter (50 in those >65 years). Mortality due to malaria was higher in those >65 years, the mean CFR reaching a 2.1% peak. Almost half (47.8%) of the notified cases originated from Mozambique and Mpumalanga Province itself constituted 50.1%. The distribution of malaria varied across the districts, highest in Ehlanzeni district (96.5%), lowest in Nkangala (<1%) and Gert Sibande (<1%). A notable decline in malaria case notification was observed following the increased IRS coverage from 2006/07 to 2008/09 malaria seasons. A distinct seasonal transmission pattern was found to be significantly related to changes in rainfall patterns (P = 0.007). Conclusion Decades of continuous IRS with insecticides have proved to be successful in reducing the burden of malaria morbidity and mortality in Mpumalanga Province between 2001 and 2009. A decline of above 50% in malaria morbidity and mortality was observed following expanded IRS coverage. These results highlight the need to continue with IRS together with other control strategies until interruption in local malaria transmission is completely achieved and alternative vector control strategies implemented. Efforts need to be directed towards the control of imported cases, interruption of local transmission and focus on research into sustainable and cost-effective combination of control interventions. / Dissertation (MSc)--University of Pretoria, 2012. / School of Health Systems and Public Health (SHSPH) / Unrestricted

Objetivos: Descrever o comportamento da Doença Meningocócica (DM) focalizando aspectos clínicos e seus desfechos, analisar o possível impacto da descentralização da assistência hospitalar, investigando também fatores associados à sua gravidade no município de São Paulo (SP), de 1986 a 2004. Metodologia: Trata-se de um estudo de corte transversal com componente descritivo e analítico, abrangendo o período de 1986 a 2004. A população de estudo abrange pacientes de DM, residentes no município de SP, notificados à vigilância. Os dados foram obtidos junto à vigilância passiva da DM e ao Instituto Adolfo Lutz de São Paulo. A descrição da doença foi efetuada segundo aspectos relativos ao tempo, espaço e pessoa. Para a investigação dos fatores associados à gravidade da DM tomou-se como variável dependente o óbito por DM e como variável independente, as exposições de interesse. Elas foram investigadas por meio das estimativas das odds ratio não ajustadas e ajustadas pela regressão logística não condicional, com os respectivos intervalos de confiança de 95 por cento. Resultados: Foram confirmados 10.087 casos de DM no município de São Paulo, durante o período de interesse. No pico epidêmico de 1995, a taxa de incidência média da DM foi de 8,1 casos/100.000 habitantes (hab), a mortalidade de 1,8 casos/hab/ano e letalidade média de 22 por cento. Crianças menores de quatro anos foram as mais atingidas, constituindo 54 por cento dos casos, principalmente entre os menores de um ano, com taxa de incidência média de 60,1/100000 casos/hab. Em 1986, o Hospital Especializado atendia 83 por cento dos casos e os Assistenciais apenas 12 por cento. No final do período estudado (2004), com a descentralização do serviço, o Hospital Especializado passou a atendeu 22 por cento dos casos e 71 por cento dos casos os Assistenciais. O Hospital Especializado manteve a letalidade anual dos casos de DM constante durante todo período, em torno de 11 por cento. A letalidade 15 dos Hospitais Assistenciais foi diminuindo gradativamente ao longo do período, inicialmente com 60 por cento e terminando com 16 por cento. Conclusão: A identificação de fatores associados à gravidade da DM e a repercussão da assistência hospital podem contribuir na melhoria das condutas clínicas, e subsidiar políticas públicas e intervenções de saúde pública / Objectives: To describe the behavior of meningococcal disease (MD) focusing on clinical features and outcomes, analyze the potential impacts of decentralization of hospital care, also investigating factors associated with the severity of MD in São Paulo (SP) city, from 1986 to 2004. Methods: This is a cross-sectional study with descriptive and analytical component covering the period 1986 to 2004. The population of the study was inhabitants in SP city, registered in the surveillance system. The data were obtained from the surveillance system of the DM MD and the Adolfo Lutz Institute of São Paulo. The descriptive analysis was presented by aspects of the time, space and person. The investigation of factors associated with the severity of the MD, it was considered as dependent variable death, and as independent variable, the exposure of interest. They were investigated by unadjusted and adjusted odds ratios by unconditional logistic regression, with their confidence intervals of 95 per cent. Results: There were 10,087 confirmed cases of MD in SP city, from 1986 to 2004. In epidemic peak (1995), the average rate of incidence of MD was 8.1 cases/100000 inhabitants (inhabit), the mortality rate was 1.8 cases/inhab/year and average case fatality rate (CFR) was of 22 per cent. Children under four years were the highest risk, representing 54 per cent of cases, especially among children under one year with average incidence rate of 60.1/100000 cases/inhab. In 1986, the specialized hospital cared 83 per cent of cases and non-specialized hospital only 12 per cent. At the end of the period studied (2004), with the decentralization of service, the specialized hospital has attended 22 per cent and 71 per cent of cases by the non-specialized. The referential hospital represented an annual CFR of MD constant in over time, around 11 per cent. The CFR of non-specialized hospital has been decreasing gradually 17 over the period, initially with 60 per cent and ending with 16 per cent. Conclusion: The identification of factors associated with the severity of DM and the impact of decentralization of the hospitals care can help in improving the clinical procedures, and support public policies and public health interventions

Abortion and severe pre-eclampsia/eclampsia remain the major causes of maternal mortality in Zimbabwe. Based on this problem, factors associated with maternal mortality due to abortion and severe pre-eclampsia/eclampsia were investigated to improve pregnancy outcomes. Cases and controls were selected from 4895 abortion and 318 severe preeclampsia/ eclampsia obstetric records to conduct a retrospective case-control study. Significant risk factors identified for reducing maternal mortality due to postabortion complications included the administration of oxytocic drugs and evacuations of the uterus whilst anaemia and sepsis apparently reduced these women's chances of survival. No significant factors could be identified which influenced maternal deaths among women suffering from severe pre-eclampsia/eclampsia. Magnesium sulphate was not routinely administered, as recommended internationally. In both groups, cases apparently received better reported quantitative care than controls. Recommendations based on this research report include improved midwifery education and in-service training, regular audits of patients' records and changed policies for managing these conditions more effectively in Zimbabwe. / Health Studies / D.

Tesis por compendio / [ES] El brote de Coronavirus SARS-CoV-2 representó un reto para la economía, la vida social y los servicios sanitarios. Justo cuando más se necesitaba la información para la planificación económica, los servicios de vigilancia y notificación no fueron capaces de ofrecer, a pesar de esfuerzos extraordinarios, datos consistentes, como así reconocieron los propios orga-nismos gubernamentales. Esta tesis incluye tres artículos publicados durante los brotes de COVID-19 y una investi-gación adicional fuera del conjunto de publicaciones. La investigación tiene como objetivo general proporcionar información a través de estimaciones alternativas. Para ello se han utilizado varias metodologías, entre ellas los modelos matemáticos de predicción epidemio-lógica, el Mejor Ajuste de Valores Relacionados (BARV), los análisis de diferentes encues-tas y la metodología bibliométrica, aprovechando u ofreciendo alternativas a los métodos bayesianos más complejos, las simulaciones de Monte Carlo o las cadenas de Markov, aun-que algunos datos obtenidos se apoyan parcialmente en estas metodologías. Cada artículo aborda un tema esencial relacionado con la pandemia COVID-19. La primera publicación se centra en los datos epidemiológicos básicos. Se refiere al primer brote de COVID-19, estimando su duración, incidencia, prevalencia, tasa de fallecimientos sobre infectados (IFR) y tasa de fallecimientos sobre casos (confirmados) (CFR). Como dato destacado de este trabajo, se previó que la seroprevalencia era demasiado baja para que la inmunidad de rebaño desempeñara algún papel. Aunque el valor obtenido fue aproxima-damente un 2% inferior al que demostró posteriormente un estudio poblacional (Instituto Carlos III), la conclusión sobre la inmunidad de rebaño no cambió, y los resultados confir-maron la idoneidad del enfoque. La segunda publicación se centró en las cuestiones legales y las noticias falsas, analizando la reticencia de la población a vacunarse, el impacto de las falsas noticas en estos comporta-mientos, las posibilidades legales de hacer obligatoria la vacuna y las posibles acciones contra los profesionales de la salud que publican noticias falsas. La principal conclusión fue que, aunque se podría encontrar una vía legal para la obligatoriedad de la vacunación, y para la persecución gubernamental de las noticias falsas, la opinión ciudadana parece prefe-rir que la administración no tome la iniciativa, por lo que se recomienda promover y fomen-tar la concienciación ciudadana. La tercera publicación presentó un modelo matemático simplificado para la estimación del coste-efectividad de la vacuna contra la COVID-19. Se actualizan los datos de dos fechas para la estimación de los costes directos para el sistema sanitario debidos a la COVID-19, computando el coste por ciudadano y por Producto Interior Bruto (PIB), así como el coste-efectividad de la vacuna. La estimó razón de coste-efectividad incremental (RCEI) para dos dosis por persona a un coste de 30 euros cada dosis (incluida la administración). Asumien-do al 70% de efectividad y con el 70% de la población vacunada resultó ser de 5.132 euros (4.926 - 5.276) por año de vida ajustado a calidad (AVAC) ganado (a 17 de febrero de 2021). Una cifra que desciende cada día de pandemia activa. Se incluyó una investigación adicional, no incorporada en el conjunto de artículos, centrada en los recursos humanos y la educación. Se analizaron los temas preocupan al personal de primera línea, es decir, a la enfermería, y cómo la pandemia ha afectado a sus publicaciones científicas, como índice de los cambios en el clima laboral que sufre este colectivo. Median-te un estudio bibliométrico comparativo entre las publicaciones de 2019 y 2020, se analizó el cambio de temas y ámbitos como reflejo del impacto del COVID-19 en el personal de enfermería. Así se comprobó que, en los ámbitos de enfermería de atención especializada, y sobre todo e / [CA] El brot de Coronavirus SARS-CoV-2 va representar un repte per a l'economia, la vida soci-al i els serveis sanitaris. Quan més es necessitava la informació per a la planificació econò-mica, malgrat esforços extraordinaris, els serveis de vigilància i notificació no van ser capa-ços d'oferir dades consistents, com així van reconèixer els mateixos organismes governa-mentals. Aquesta tesi inclou tres articles publicats durant els brots de COVID-19 i una investigació addicional fora del conjunt de publicacions. La investigació té com a objectiu general pro-porcionar informació a través d'estimacions alternatives. Per a això s'han utilitzat diverses metodologies, entre elles els models matemàtics de predicció epidemiològica, el Millor Ajust de Valors Relacionats (BARV), les anàlisis de diferents enquestes i la metodologia bibliomètrica, aprofitant o oferint opcions alternatives als mètodes bayesians més comple-xos, les simulacions de Montecarlo o les cadenes de Markov, tot i que algunes dades obtin-gudes es recolzen parcialment en aquestes metodologies. Cada article aborda un tema essen-cial relacionat amb la pandèmia COVID-19. La primera publicació se centra en les dades epidemiològiques bàsiques. Es refereix al pri-mer brot de COVID-19, calculant la seua durada, incidència, prevalença, taxa de defuncions sobre infectats (IFR) i taxa de defuncions sobre casos (confirmats) (CFR). Com a dada des-tacada d'aquest treball, es va preveure que la seroprevalença era massa baixa perquè la im-munitat de ramat exercirà algun paper. Tot i que el valor obtingut va ser aproximadament un 2% inferior al demostrat posteriorment en un estudi poblacional (Institut Carles III), la conclusió sobre la immunitat de ramat no va canviar, i els resultats van confirmar la idoneï-tat de l'enfocament. La segona publicació es va centrar en les qüestions legals i les notícies falses, analitzant la reticència de la població a vacunar-se, l'impacte de les falses notícies en aquests comporta-ments, les possibilitats legals de fer obligatòria la vacuna i les possibles accions contra els professionals de la salut que publiquen notícies falses. La principal conclusió va ser que, tot i que es podria trobar una via legal per l'obligatorietat de la vacunació, i per la persecució governamental de les notícies falses, l'opinió ciutadana sembla preferir que l'administració no prenga la iniciativa, per la qual cosa es recomana promoure i fomentar la conscienciació ciutadana. La tercera publicació va presentar un model matemàtic simplificat per a l'estimació del cost-efectivitat de la vacuna contra la COVID-19. S'actualitzen les dades de dues dates per a l'estimació dels costos directes per al sistema sanitari deguts a la COVID-19, computant el cost per ciutadà i per Producte Interior Brut (PIB), així com el cost-efectivitat de la vacuna. La va estimar raó de cost-efectivitat incremental (RCEI) per dues dosis per persona a un cost de 30 euros cada dosi (inclosa l'administració). Assumint al 70% d'efectivitat i amb el 70% de la població vacunada va resultar ser de 5.132 euros (4.926 - 5.276) per any de vida ajustat a qualitat (AVAQ) (a 17 de febrer de 2021). Una xifra que descendeix cada dia de pandèmia activa. Es va afegir una investigació addicional, no inclosa en el conjunt d'articles, centrada en els recursos humans i l'educació. Es van analitzar els temes que preocupen al personal de pri-mera línia, és a dir, a la infermeria, i com la pandèmia ha afectat les seues publicacions cien-tífiques, com a índex dels canvis en el clima laboral que pateix aquest col·lectiu. Mitjançant un estudi bibliomètric comparatiu entre les publicacions de 2019 i 2020, es va analitzar el canvi de temes i camps com a reflex de l'impacte del COVID-19 en el personal d'infermeria. Així es va comprovar que en els àmbits d'infermeria d'atenció especialitzada, i sobretot en atenció primària, els principals problemes detectat / [EN] The SARS-CoV-2 Coronavirus outbreak has posed a challenge to the economy, social life, and health services. Just when information was most needed for economic planning, moni-toring, and reporting services were unable, despite extraordinary efforts to provide con-sistent data, as government agencies themselves acknowledged. This thesis includes three articles published during the COVID-19 outbreaks and additional research outside the publication set. The overall aim of the research is to provide infor-mation through alternative estimates. Several methodologies have been used, including mathematical models for epidemiological prediction, Best Adjustment of Related Values (BARV), analyses of different surveys and bibliometric methodology, taking advantage of or offering an alternative to, more complex options such as Bayesian methods, Monte Carlo simulations or Markov chains, although some data obtained are partially supported by these methodologies. Each article addresses a key issue related to the COVID-19 pandemic. The first publication focuses on basic epidemiological data. It refers to the first outbreak of COVID-19, estimating its duration, incidence, prevalence, Infection Fatality Rate (IFR) and Case Fatality Rate (CFR). As a highlight of this work, the seroprevalence was anticipated to be too low for herd immunity to play a role. Although the value obtained was approximate-ly 2% lower than that subsequently demonstrated by a population-based study (Instituto Carlos III), the conclusion on herd immunity remained unchanged, and the results con-firmed the appropriateness of the approach. The second publication focuses on legal issues and fake news, analysing reluctance to be vaccinated in the population, the impact of fake news on these behaviours, the legal possi-bilities of making vaccination mandatory, and possible actions against health professionals who publish fake news. The main conclusion was that, although a legal avenue could be found for mandatory vaccination and for governmental prosecution of fake news, public opinion seems to prefer that the authorities do not take the initiative, therefore it recom-mends promoting and encouraging public awareness. The third publication presented a simplified mathematical model for estimating the cost-effectiveness of the COVID-19 vaccine. Data from two dates were obtained for the estimation of the direct costs to the health system due to COVID-19, computing the cost per citizen and per Gross Domestic Product (GDP), as well as the cost-effectiveness of the vaccine. The estimated incremental cost-effectiveness ratio (ICER) was calculated for two doses per person at a cost of 30 euros per dose (including administration). Assuming 70% effectiveness and with 70% of the population vaccinated, it was found to be 5,132 euros (4,926 - 5,276) per quality-adjusted life year (QALY) gained (as of 17 February 2021). The figure decreases with each day of the active pandemic. Additional research not included in the set of articles focuses on human resources and education. It analyses the concerns of frontline staff, i.e., nurses, and how the pandemic has affected their scientific publications, as an index of the changes in the work climate experienced by this group. Through a comparative bibliometric study of publications in 2019 and 2020, the change in topics and fields was analysed, as a reflection of the impact of COVID-19 on nursing staff. It was found that in the fields of specialised care nursing and above all in primary care, the main problems detected are those related to protective measures and psychological factors, while the publications of nursing staff in nursing homes showed an increase in topics related to management and organisation. Finally, some aspects of the implementation of telecommuting and distance learning have been reviewed. Some of the boosts in this field resulting from the pandemic could be very useful and remain in the future, such as the incorporation of telewo / Marco Franco, JE. (2021).
