Human African trypanosomiasis (HAT) in the Republic of Congo: why the Congolese population is reluctant to screening?

INTRODUCTION: human African trypanosomiasis (HAT) is a neglected tropical infection, and surveillance of the disease relies on community participation in screening. This study aimed to identify the main factors associated with low community uptake of the HAT screening in endemic districts in the Republic of Congo. METHODS: a cross-sectional survey was carried out during a sensitisation campaign about HAT in the districts of Mpouya, Ngabé and Loudima, which are endemic for the disease. After signing the informed consent form, participants were organized into groups of 10 for focus group discussions (FGDs). A list of questions was used for guiding the discussion, addressing understanding of the disease and reasons for refusing screening. RESULTS: out of 220 recruited individuals (corresponding to 22 FGDs), 58.6% were men. The majority of the respondents described HAT as a rural disease (48.2%) or as a witchcraft (22.3%). Among the clinical signs cited by the participants, sleep disorder (40%) was the most common answer, followed by prolonged fever (19.5%) and madness (14.1%). The main reasons for non-adherence to HAT screening was the fear of lumbar puncture (45.9%) and stigmatisation (22.3%). CONCLUSION: the findings of this study suggest that more effort should be put into raising awareness of HAT and the benefits of screening amongst the Congolese population, in order to strengthen the national disease control program.
