Parasitic worms
Developing missing cures for disabling and stigmatizing diseases
Caused by parasitic worms and most common in tropical and subtropical regions, river blindness, lymphatic filariasis, and schistosomiasis affect millions of people worldwide. They take their greatest toll on people affected by poverty, malnutrition, and poor sanitation and housing – and can cause debilitating illness, social exclusion, long-term disability and, in severe cases, death.
There are no cures for neglected parasitic worm diseases. Current strategies to control their spread mostly rely on the mass administration of anthelminthic drugs that must be administered to nearly all people in endemic areas for five to ten consecutive years.
What we’re doing for parasitic worm diseases
We are joining forces with partners to develop new treatments that can cure parasitic worm diseases before they cause lasting harm – and working to make sure they are suitable for all people who need them, including young children and pregnant women.

River blindness
Causes vision loss and eventually permanent blindness if left untreated.

Schistosomiasis
Can cause organ damage and long-term reproductive harm – especially for women and girls.

Lymphatic filariasis
Causes painful and disabling swelling of the limbs requiring continuous medical care.
