Comparison of community-wide, integrated mass drug administration strategies for schistosomiasis and soil-transmitted helminthiasis : a cost-effectiveness modelling study

guidelines. Treatment every 6 months was also highly cost effective in three out of four communities.; Integrated, community-wide MDA programmes for schistosomiasis and soil-transmitted helminthiasis can be highly cost effective, even in communities with low disease burden in any helminth group. These results support an urgent need to re-evaluate current global guidelines for helminthiases control programmes to include community-wide treatment, increased treatment frequency, and consideration for lowered prevalence thresholds for integrated treatment.; Stanford University Medical Scholars Programme, Mount Sinai Hospital-University Health Network AMO Innovation Fund.
