Trypanosomiasis: a public health priority in Cameroon.

From a historical standpoint and the present distribution of the disease, human trypanosomiasis, in spite of its comparatively low incidence, still remains a public health priority in Cameroon, requiring both national and international support for control measures. The geographical position of the country within the Glossina belt, certain cultural practices, agro-industrial activities, and an improving transport system are current factors favouring the spread of the disease. Similarly the changing pattern of the disease, ignorance and the lack of valid diagnostic and safe chemotherapeutic tools are some obstacles to current control measures.
