What is human african trypanosomiasis ?
Human African trypanosomiasis (HAT), also known as sleeping sickness, is a parasitic disease transmitted by the bite of the 'Glossina' insect, commonly known as the tsetse fly.
The disease mostly affects poor populations living in remote rural areas of Africa. Untreated, it is usually fatal. Travelers also risk becoming infected if they venture through regions where the insect is common. Generally, the disease is not found in urban areas, although cases have been reported in suburban areas of big cities in some disease endemic countries.
