RHODESIAN SLEEPING SICKNESS
Please CLICK on image & underlined links for details:
The parasite of Rhodesian sleeping sickness is Trypanosoma brucci rhodesiense, which produces a more virulent disease than the Gambian type. Death usually occurs after just a few weeks or months. But it is not as widespread, being more restricted to Malawi, Zambia, Tanzania, Zimbabwe and Mozambique and the area around Lake Victoria in Kenya and Uganda (Service 2008).
Important vectors are Glossina morsitans, G. pallidipes and G. fuscipes, which draw blood from a variety of game and domestic animals. The flies occur primarily in wild areas that are not heavily populated by humans. Reservoir hosts are the many wild bovid animals present (e.g., black buffalo, etc.).
