Summary

This study compares two drugs, ivermectin and moxidectin, to see which works better at controlling river blindness and other common infections like intestinal worms and scabies in Angola. Over 52,000 people in 20 village groups will receive one of the drugs once a year for four years. The goal is to find the best way to reduce these diseases in the community and help guide global treatment policies.
