    A cross-sectional study wns undertaken to determine the prevalence of camel trypanosomiasis and to identify factors associated with the disease in the southern nlngdands of Ethiopia. Multistage sampling was employ..:d as sampling method. Wet blood smeJrs, buTy com technique and antibody ELISA were utilized as diagnostic techniques to delennine the prevalence. A herJ health management questionnaire was also used to collect rdevant infor'tion on factors associated with the disease. Furthe rmore, a parallel Slirvey of the helminth status was undertaken in dry season to assess a possible association with low pev readings. A total of 31..J. camels in 81 herds and 285 camds in 74 herds were sampled during wel and dry season, respectively. In rainy season sampJ.es prevaknces of 10.1 % using parasitological methods and of 56.5% using antibody ELISA were found were found whereas parsitological methods revealed an infection 2.8% in dry season Aeg ecological conditionas and season were found to the disease a cumulative incidence of 0.03 and an incidence density of 3 cases per 10.000 animal days points to an extremely low disease dymamic during the dry season Tevansi was most common cause of camel trypanosomiasis ,Tvivax was found in twe camels
