African Sleeping Sickness, also known as Human African Trypanosomiasis (HAT), is a parasitic infection caused by the protozoan parasites Trypanosoma brucei gambiense and Trypanosoma brucei rhodesiense. Transmitted through the bite of infected tsetse flies, this neglected tropical disease primarily affects sub-Saharan Africa. Two forms of the disease exist, with T. b. gambiense causing the chronic form prevalent in West and Central Africa, and T. b. rhodesiense causing the acute form found in East Africa. The initial stage of the disease is characterized by fever, headaches, joint pain, and itching. As the infection progresses, parasites invade the central nervous system, leading to neurological symptoms such as sleep disturbances, confusion, and eventually, a profound sleep-wake cycle disruption, giving the disease its name. Without proper treatment, African Sleeping Sickness has the potential to result in fatality. Treatment options depend on the stage of the disease and the species of the infecting parasite. Early-stage cases may be treated with medications such as pentamidine or suramin, while advanced cases often require drugs like melarsoprol or eflornithine. Control efforts involve vector control measures, such as tsetse fly eradication, and surveillance programs to identify and treat cases promptly.
