Purpose: The aim of this study is to establish a new tool for schistosomiasis transmissions sites prioritization in a context of remedial interventions. Indeed, this disease causes many drawbacks specially marked in socio-economic term. Its burden is estimated to 70 million Disability Adjusted Life Years.
Methods: Four disease related factors have been identified according to disease transmission cycle that are human water contacts, water fecal pollution, mollusk densities and mollusk infection rates and monitored through sites observation, bacterial culture, mollusk collection and light exposure respectively. For a given criteria, the score 1 is given to the point of lowest value, the other points scores are the quotient of their value by the lowest; the mean score of the 4 criteria is the Schistosomiasis Infection Indice of a given point.
Conclusion: This study produces a unique value parameter that will assist planners and decision makers in their activities and it appears to be very relevant because it takes short time, at most 10 days then less funds, it provides recent and actual data that can be used to map the zones at risk, it also allows disease exposure monitoring in real time and periods and zones of high risk identification; it contributes to identify sex and/or age groups at high risk. This tool is a relevant spatio-temporal guidance of decision makers and health planners. However, it may be improved by including direct data related to the pathogens and human specific fecal pollution indicators that are the ongoing steps of our investigation. On the whole, a tool for a real time disease monitoring is needed and this one contributes very well to make up a shortage.
Key words: Schistosomiasis Infection Indice; water contacts; fecal pollution; mollusks density; mollusks infection rate.
