== African trypanosomiasis ==

Sleeping sickness or [[African trypanosomiasis]] is a [[parasitic]] disease in humans. Caused by [[protozoa]] of genus ''[[Trypanosoma]]'' and transmitted by the tsetse fly, the disease is endemic in regions of [[sub-Saharan Africa]], covering about 36 countries and 60 million people. An estimated 50,000 – 70,000 people are infected and about 40,000 die every year. The three most recent [[epidemic]]s occurred in 1896 -1906, 1920, and 1970.

Studies of the tsetse fly show that females generally mate only once (occasionally twice). Studies found this process to be effective in preventing the scourge.
