Sleeping sickness is a disease caused by infection with trypanosoma parasite. Humans get this disease from bites from tsetse fly which has been infected from other infected humans or animals. This disease is caused by two subspecies of Trypanosoma brucei namely; Trypanosoma brucei gambiense in West and Central Africa, and Trypanosoma brucei rhodesiense in East Africa.
Sleeping sickness poses threat to life and mostly affects poor rural populations, causing significant harm. People who travel to endemic regions may also be at risk of getting infected.
This disease affects the brain and if proper care is not given could result in lethal conditions and eventually death.
