Neglected tropical diseases

We help to treat and prevent five debilitating diseases that affect more than a billion people. These parasitic and bacterial infections are known as neglected tropical diseases (NTDs).

Read the statement

Neglected tropical diseases are a major cause of preventable blindness. They are most prevalent in rural regions, poor urban areas and conflict zones.

The diseases affect more than a billion people worldwide, and can cause severe and lifelong impairment.

Yet these diseases can be prevented, treated and eliminated.

Sightsavers works with thousands of local volunteers to distribute millions of donated treatments to protect people against NTDs, and teach them about the importance of good hygiene to prevent infection.

Here you can find out more about the five neglected tropical diseases that Sightsavers works to treat and prevent (two of which are blinding, and three that are non-blinding), as well as the progress being made to combat them and, in some cases, eliminate them completely.
