Full textCholera is an epidemic acute watery diarrhea caused by toxigenic bacteria Vibrio cholerae O1. Its environment determinants have been at the source of a popular paradigm. Many recent control strategies have shown little efficiency in Africa or in Haiti, but they could be improved by a better comprehension of the epidemics dynamic. The bibliographic synthesis of environment influences on cholera in Africa highlights the limits of the environmental paradigm on this continent. A multidisciplinary study of the origin of cholera epidemic in Guinea in 2012 strongly suggests it was humanly imported from nearby Sierra Leone. A space-time description of cholera in Mozambique demonstrates heterogeneous transmission patterns and challenges the concept of cholera endemicity. Since its importation in Haiti in October 2010, cholera transmission also exhibits a marked spatio-temporal heterogeneity. Cholera important retraction during the dry season and its absence of significant establishment in the Haitian environment suggest it may be possible to rapidly eliminate cholera in the country, provided that every outbreak focus receives a targeted response. An elimination strategy based on our recommendations is currently implemented by Haitian Ministry of Health, UNICEF and their partners. After spectacular results in 2013 and during the first half of 2014, the situation has slowly deteriorated during the rainy season. However, cholera elimination during the coming dry season remains realistic provided that we succeed in persuading and remobilizing the partners present on the field

Full textCholera is a severe acute diarrhoeal disease caused by Vibrio cholerae, a gram-negative bacterium that colonises warm, saline, alkaline surface waters, often in association with phytoplankton or zooplankton. After 50 years of introduction of cholera in Africa, the disease is affecting African countries in a very strong way. The objective of the PhD work was to try to elucidate the causes of cholera endemicity in Africa and on the scale of a rift sector, Lake Kivu and the Katana health zone, located in the Democratic Republic of Congo.A map of geographical areas at risk was drawn up for the African continent, showing a greater number in the Rift Valley and around the Lake Chad basin. This first study highlighted the relationship between the existence of salt water bodies (lagoons, lakes, rivers) and the endemicity of the disease. Under these environmental conditions, the cholera risk is exacerbated in economically weak and unstable countries. In continental Africa, the study showed a good overlap between areas of high volcano-tectonic activity (African Rift Valley, Lake Chad basin) and cholera endemicity. The study of cholera dynamics in a Rift Valley health zone (Katana province in DRC) demonstrated that volcanic activity plays a major role in the occurrence and maintenance of cholera epidemics in the African Rift Valley. The work showed that volcano-tectonic activity (measured by the SO2 concentration in the smoke plume of the Nyiragongo volcano) governed the temperature and salinity of the waters of Lake Kivu, and the presence of the bacillus in the lake water and fish. The study was able to show that the environmental presence of the bacillus in the lake was very strongly linked to the epidemiological data of the Katana area. A study of the practices of the inhabitants of Bukavu showed that individual contamination with cholera is linked to the handling and consumption of lake products (water or fish).This doctoral work has made it possible to target areas at risk of cholera in Africa, and the impact of volcanic activity in the dynamics of cholera in continental Africa. This information is necessary to build effective and targeted strategies to fight cholera in the African continent in accordance with the global roadmap developed by the Global Task Force on Cholera Control in 2017

Full textIn the context of communicable diseases (e.g. malaria, cholera, etc.), proximity to environments favoring transmission (e.g. breeding sites or sources of contagion, etc.) influences the infection risk, thus causing a spatial heterogeneity of this risk. However, in randomized trials, these environmental aspects are not fully observable (e.g. breeding sites).The aim of this thesis was to model this spatial heterogeneity of environmental risk not observed in a prevention trial.In the first section, using a simulation study, we showed that randomization alone did not eliminate the bias due to the spatial heterogeneity of environmental risk. We showned that the SPDE (Stochastic Partial Differential Equations) approach estimated with the INLA (Integrated Nested Laplace approximations) method and modeling this spatial heterogeneity through the localization of individuals by a Gaussian field defined by the Matèrn covariance, allowed to correct this bias.The second section focused on modeling the spatial heterogeneity of environmental risk in the context of recurrent events. We re-analyzed the data from two malaria prevention trials in Mali: One evaluating the effect of adding azithromycin to Seasonal Malaria Chemoprevention (SMC) against malaria in children under 5 years of age in Bougouni, and the other evaluating the efficacy of malaria protection measures in Bandiagara.In the last section, we have elaborated a user guide for the Bayesian SPDE model with the INLA estimation method
