Trypanosomiasis was 1st identified in Angola in 1871, in the Quixama
region (Kwanza River area, south of Luanda).
Increasing disease rates since the early 1980's have been ascribed to
civil unrest and do not reflect a general trend among endemic
countries. See graph at
<http://exhibit.gideononline.com/Trypano-Africa.jpg>.
The disease is endemic to 7 of the country's 18 provinces. Risk areas
include the northern provinces of Bengo, Kwanza Norte and Kwanza
Sul, Luanda, Malange, Uige, and Zaire. Widespread disease in the
southern provinces of Kunene, Huambo, Namibe, and Huila was 1st
reported in 2003. 2.5 to 4 million persons are considered at risk in
6000 villages north of the Kwanza River.
_Trypanosoma brucei gambiense_ predominates (mostly in the
northwestern region: Zaire, Uige, Luanda and Kwanza Norte). Sporadic
disease due to _Trypanosoma brucei rhodesiense_ is also reported.
Tsetse flies are present in 14 of Angola's 18 provinces. The local
vectors are _Glossina palpalis_ (found in Zaire, Bengo, Kwanza Norte,
Kwanza Sul and Cuando Cubango), _G. fuscipes_ ssp. quanzensis and
martinii (found in Uige, Malanje, Lunda Norte and Lunda Sul), and _G.
morsitans_ (found in Malanje, Kwanza Sul, Bia, Moxico and Cuando
Cubango).
