COUNTDOWN on schistosomiasis towards 2020: From global expectations to local realities

Professor J. Russell Stothard 

Liverpool School of Tropical Medicine

Schistosomiasis is a waterborne parasitic disease in sub-Saharan Africa, particularly common in rural populations living in impoverished conditions. With the scale-up of preventive chemotherapy offering praziquantel, national campaigns will transition from morbidity- to transmission-focused interventions. In line with the WHO 2012-2020 Roadmap, there will be forthcoming scale-up of treatment coverage in school-aged children and formal investigation of actual or expected declines in environmental transmission will be required. For the former there is an international WHO preventive chemotherapy database monitoring progress, however, for the latter there are no international or national guidelines to do so in sub-Saharan Africa. In additional, treatment of school-aged children will likely not be sufficient to gain an! d sustain control in certain settings. In this presentation, I provide an introduction to key practicalities and pitfalls in the control of schistosomiasis and set out some key challenges. I also introduce an attempt to develop an appropriate environmental surveillance framework drawing attention to snail-schistosome relationships. With effective preventive chemotherapy, community parasitaemia will decline and as detection of egg-patent infections in people becomes rare, careful sampling of schistosome infections in freshwater snails and in the environment with robust species-specific DNA assays will be needed. To gauge future progress in transmission-focused settings, appropriate metrics, derived from observed prevalence(s) as compared with predetermined infection thresholds in snails, could provide a clearer insight into contamination- and exposure-related dynamics. Its application could be twofold, either to certify areas currently free from schistosomiasis transmission ! or to red-flag recalcitrant locations needing extra intervention effort. To shed light on the latter and highlighting research within COUNTDOWN (a 5-year implementation research consortium funded by DFID, UK), I provide some key examples from recent work undertaken in Uganda and Cameroon on urogenital and intestinal schistosomiasis.
