Abstract
The Human African Trypanosomiasis (HAT) is a disabling and fatal disease caused by a vector-borne parasite still impacting in residual hotbeds. The aim of our study was to update the epidemiological data of HAT in one of Central African Republic foci after the (2012-2014) period of conflict. The survey was carried out in 24 villages in the Bilolo's municipality where 4788 persons were examined by the CATT (Card Agglutination Trypanosomiasis Test) technique. The identified cases were submitted to a serological titration test followed by parasitological testing for confirmation. The cytorachia technique was used for clinical phase determination. The CATT has identified 221 persons, of which 54 were confirmed by serological titration test, giving a seroprevalence of 1.12%. Parasitological confirmation was obtained for 15 patients. Our study showed the abundance of Trypanosoma parasites in the Bilolo municipality. However, since 2007, no case of HAT had been diagnosed in this focus after screening, treatment and vector control.
