Résumé
Bacterial diseases resulting from exposure to bacteria present in surface water and soil are generally poorly diagnosed, even though they are likely to have a major impact in terms of public health. This is particularly the case for leptospirosis and melioidosis, which are common diseases in the intertropical zone but are rarely reported in most countries. Their epidemiology remains largely linked to the rainy season, but epidemics can also be fostered by extreme climatic events such as flooding.In response to this situation, we are developing tools for predicting the environmental conditions that are conducive to the transmission of these diseases, in order to bring this knowledge to health managers and set up early-warning systems. We use information from Sentinel-1 and Sentinel-2 satellites, obtained timely on a fine scale to produce a routine monitoring of relevant health indicators.This presentation will provide an update on this work, currently underway in South-East Asia, with the development of local satellite data processing capabilities and the implementation of dashboards or health information systems that integrate climatic and environmental data, with a specific focus on leptospirosis and other climate-sensitive diseases.
