The following background information on Trypanosomiasis in Angola is abstracted from GIDEON:

Trypanosomiasis was first identified in Angola in 1871, in the Quixama region (Kwanza River area, south of Luanda).

A resurgence of disease rates during the 1980’s does not represent a general phenomenon for Africa, and appears to be related to civil unrest in the country. See graph

Trypanosomiasis is endemic to 7 of the country’s 18 provinces.
- Risk areas include the northern provinces of Bengo, Kwanza north and Kwanza south, Luanda, Malange, Uige, and Zaire.
- Widespread disease in the southern provinces of Kunene, Huambo, Namibe, and Huila was first reported in 2003.
- 2.5 to 4 million persons are considered at risk in 6,000 villages north of the Kuanza River.

Trypanosoma brucei gambiense predominates (mostly in the northwestern region – Zaire, Uige, Luanda and Cuenza 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).
