Abstract
A case-control study on risk factors of Trypanosoma brucei gambiense human african trypanosomiasis was carried out in 111 patients diagnosed in the three main foci of Ivory coast. Each case was age and sex matched with one seronegative control living in the same locality. Based upon previous epidemiological surveys conducted in similar areas, the potential risk factors were identified and assessed using a standard questionnaire. The study demonstrates that in the forest area of Ivory coast human trypanosomiasis in a behavioral disease affecting mainly coffee and cocoa farmers. The allogenous populations coming from sudano-sahelian savannah are more exposed to the disease than other ethnic groups. People sleeping at the farm (encampments) are more likely to become infected than those living at the village (ODDS-Ratio = 4.5). People fetching water in natural holes and pools have an increased risk (ODDS-Ratio = 3.6). Cases reported more often than controls that they are foodstuffs dealers from the farms to the villages (ODDS-Ratio = 13.0). These results are consistent with data from previous studies. We identified preventable risk factors, upon which interventions should be carried out to reduce the incidence of the disease. The possibility of using these findings to improve sleeping sickness control programme in the forest areas of Ivory Coast is discussed.
