Monitoring the impact of a mebendazole mass drug administration initiative for soil-transmitted helminthiasis (STH) control in the Western Visayas Region of the Philippines from 2007 through 2011

The WOW-V initiative was launched in 2007 to control morbidity from soil-transmitted helminthiasis (STH) in three Western Visayas provinces. From 2009 to 2011, however, cumulative STH and moderate/heavy intensity infections increased overall despite initial improvements from baseline.
