DISEASE
Soil transmitted helminths (STH) infect an estimated 1.45 billion people globally [There are several challenges influencing the effectiveness and sustainability of school-based deworming. For example, some children do not attend school and thus may not have access to deworming [Mathematical models suggest that transitioning from school-based MDA to community-wide MDA (cMDA) could potentially address inequities in MDA treatment coverage and reduce the number of years needed to deliver school-based treatment at scale by treating adult reservoirs of disease in the community, leading to STH transmission interruption [The feasibility of STH transmission interruption by cMDA with a community-based cluster randomized trial, the DeWorm3 study, is ongoing in India (in the state of Tamil Nadu), Benin and Malawi and is in the surveillance phase [
