In recent years, 7, new cases of West African trypanosomiasis have been reported to the World Health Organization annually. However, many cases are not recognized or reported and the true number of annual cases is likely to be higher. Cases of West African trypanosomiasis imported into the United States are extremely rare.
A person gets West African trypanosomiasis through the bite of an infected tsetse fly. Occasionally a pregnant woman may pass the infection to her baby.
In theory, the infection can be transmitted through a blood transfusion, but such cases rarely have been documented. Is West African trypanosomiasis a serious illness? West African trypanosomiasis is eventually fatal if it is not treated.
Where can I contract West African trypanosomiasis?
Tsetse flies are found only in Africa and they live in rural environments. West African trypanosomiasis can be contracted in parts of central Africa and in a few areas of West Africa.
What are the signs and symptoms of West African trypanosomiasis? Occasionally, within 1 to 3 weeks, the infective bite develops into a red sore, also called a chancre.
Several weeks to months later, other symptoms of sleeping sickness occur. These include fever, rash, swelling of the face and hands, headaches, fatigue, aching muscles and joints, itching skin, and swollen lymph nodes.
Weight loss occurs as the illness progresses. Progressive confusion, personality changes, daytime sleepiness with nighttime sleep disturbances, and other neurologic problems occur after the infection has invaded the central nervous system.
