Transmission is occurring in seven provinces in the north Angola reported cases 1995-2005 and the 10 years tendency curve east, namely Bengo, Kuanza-Norte, Kuanza-Sud, Luanda, Malanje, Uige and Zaire. The Instituto de Combate e 9000 Controlo das Tripanossomiases (ICCT) is leading and 8000 coordinating all control activities in collaboration with 7000 MSF, Caritas, Instituto Portugues de Medicina Preventiva, 6000 Fundanga and projects of the Belgian and French bilateral 5000 co-operation. The ICCT receives an important financial support from 4000 New Cases New the Angolan Government and has managed to establish 3000 13 mobile teams. This, however, remains insufficient in 2000 the light of the geographical extent and population size 1000 of the endemic areas.

However, trypanosomiasis cases have not been reported from that area for decades and it is believed that transmission no longer occurs. A large tsetse fly control programme has been implemented for many years in this area. The country has excellent health structures but no specific HAT surveillance system, for which there is apparently no need.

Interruption of 16 local of transmission is supported by the fact that last survey in 14 the area, carried out in February 2005, did not diagnose any 12 autochthonous case.
