Sleeping sickness, also called "human African trypanosomiasis", is a widespread tropical disease that can be fatal if not treated. It is spread by the bite of an infected tsetse fly (Glossina Genus), a species native to the African continent. Sixty million people who live mainly in rural parts of East, West and Central Africa are at risk of contracting sleeping sickness.

Treatment: Pentamidine injections protect against T. b. gambiense. But not against T. b. rhodesiense . Because this medicine is toxic, using it for prevention is not recommended.Insect control measures can help prevent the spread of sleeping sickness in high-risk areas.
Since 2000 the WHO, assisted by partners, has been working hard to contain African sleeping sickness. Thanks to screening programs and the provision of drugs the number of cases has been declining sharply: the number of new cases reported fell below 10,000 for the first time in 2009; the estimated total number of cases had declined from 300,000 in 1998 to 30,000 in 2009.
