Where We Work

A Global Effort

Our Country Partners

In 2020 we partnered with 45 countries (or regions) in Africa, Asia, the Middle East, and South America to distribute Mectizan® for the elimination of river blindness (also known as onchocerciasis) and lymphatic filariasis (LF). A total of 416.8 million treatments were approved, a significant increase from 2019. This total included 355.3 million treatments in countries where LF and river blindness are co-endemic and 61.5 million treatments in 13 countries implementing “triple therapy,” also known as IDA (which stands for ivermectin [Mectizan], diethylcarbamazine [DEC], and albendazole).
