[Towards the control of the endemic of sleeping sickness in Nola-Bilolo focus, Central African Republic].

Abstract : Sleeping sickness is more prevalent in three historical regions of Central African Republic. Control measures were organized by the colonial authorities through health services to fight against this disease and other major diseases. Multivariate analysis and the government helped in controlling the disease in the focus of Nola-Bilolo, which was formerly hyperendemic. The authors report the results of the control measures that resulted in the extinction of the disease in this outbreak. This is a retrospective study from 1991 to 2008, and the data were collected from the National Program to fight against human African trypanosomiasis in Bangui and in the diagnostic and treatment center of Nola. It was highly endemic, with more than 300 cases recorded in the year 1991. The average number of cases was 200.8 per year between 1992 and 1998. Less than 50 cases per year were recorded from 2000 to 2006, and no cases have been detected since 2007. 69.35% of the patients were actively screened. 5,000 conical deltamethrin-impregnated traps (Gouteux and Lancien) had been used in 15 districts in the city of Nola and 46 surrounding villages by 20 trappers fully supported by the program. This is an example of regular active mass screening. Systematic treatment of detected cases and well-conducted vector control measures give hope to the affected populations to live peacefully in order to contribute to the development of their country.
