Situation and trends

Schistosomiasis remains a public health problem in several parts of the world, particularly in Africa where 92% of all the people requiring preventive chemotherapy for schistosomiasis live. Data on treatment are collected to measure the progress being made towards achieving the targets set by World Health Assembly resolutions to reach >75% all school-aged children who are at risk of morbidity from schistosomiasis and soil-transmitted helminthiasis. Of the 78 countries considered endemic for schistosomiasis, only 52 countries have populations requiring preventive chemotherapy. The total number of people in need of preventive chemotherapy globally in 2015 was 218.8 million, of which 118.5 million were school-aged children. Data reported for 2015 show that more than 66 million people received preventive chemotherapy for schistosomiasis which is equivalent to 28.2% global coverage.
