Guidelines for the treatment of human African trypanosomiasis. Web Annex A. Commissioned by WHO Cochrane Response
WHO Guidelines for the Treatment of Human African Trypanosomiasis. Web Annex B
HAT diagnosis relies on laboratory techniques because clinical signs and symptoms are unspecific. Serodiagnostic tests exist only for Tbg and are based on the detection of specific antibodies, thus they are not confirmatory of infection. With the current low disease prevalence, the positive predicti

ve value of serological tests is particularly low. Field-applicable tools include the card agglutination test for trypanosomiasis (CATT) used mainly in active screening by specialized mobile teams, and the rapid diagnostic tests that are more suitable for individual testing at point-of-care. Confirmation of Tbg infection requires microscopic examination of body fluids necessitating specific training. The best performing methods are laborious and reach 85–95% diagnostic sensitivity when performed by skilled personnel.

The Atlas database is built by the systematic collection of information around every HAT case detected worldwide, actively or passively, in endemic and non-endemic countries, and also on the surveillance activities carried out per village. The data are aggregated by year, by location and by some other parameters. All cases and activities are georeferenced at the village level to within an average accuracy of about 1.4 km. The Atlas contains complete information since the year 2000 from the 25 countries reporting at least one HAT case
