摘要

Coastal communities are increasingly vulnerable to waterborne disease, and particularly to pathogens whose range and abundance are sensitive to the effects of a changing climate. Increased precipitation and coastal flooding events are associated with a greater risk of drinking water contamination by enteric pathogens such as hepatitis A and E, as well as multiple Vibrio bacterial species, including the causative agent of cholera, Vibrio cholerae. The greatest incidence of these emerging and re-emerging waterborne threats is in the developing world, primarily among highly populated coastal cities in Southeast Asia and East Africa. Risk of enteric disease outbreaks can be characterized by space-based remote sensing measurements of indicators such as turbidity, biochemical oxygen demand, colored dissolved organic matter (CDOM), total suspended solids (TSS) and water temperature. Recent work has characterized individual waterborne diseases based on these criteria, although most studies have focused on pathogen abundance at a static point in time. Here, we describe efforts to integrate multiple remotely sensed indicators of enteric pathogens with climate models to characterize short to medium-term risk of waterborne disease outbreaks in highly populated urban environments in the developing world. We present a detailed case study of a recent cholera outbreak in Mombasa, Kenya, and present a forecasting method that can be utilized by local ministries of health. We consider the spatial and temporal accuracy needs of public health surveillance systems, and describe methods to integrate multiple space-based indicators into alert-based forecasting systems. We conclude by describing the iterative, community-based design methods space agencies can utilize when working with communities to combat waterborne disease.
