Where We Work

A Global Effort

Our Country Partners

In 2022 we partnered with 31 countries (or regions) in Africa, Asia, the Middle East, South America, and the Western Pacific to distribute Mectizan® for the elimination of onchocerciasis (also known as river blindness) and lymphatic filariasis (LF). A total of 377.8 million treatments were approved. This total included 316.1 million treatments in countries where LF and river blindness are co-endemic and 61.6 million treatments in 6 countries implementing “triple therapy,” also known as IDA (which stands for ivermectin [Mectizan], diethylcarbamazine [DEC], and albendazole).

Mectizan has been sent to 58 countries since the donation was announced in 1987.
