Kenya has the fifth largest camel herd in the world kept by different communities mainly in Isiolo and Marsabit counties. Camel trypanosomosis is endemic in these counties and adversely affects camel productivity. A study was carried out to evaluate the distribution of Trypanosome evansi and its vector and the appropriateness of the strategies used for control of camel trypanosomiasis by five camel keeping communities in Marsabit and Isiolo counties. . A total of 828 camels were randomly sampled in 5 sites in Isiolo and 4 sites in Marsabit County.  Blood samples were collected for packed cell and parasitological determinations and appropriate trapping devices for biting flies evaluated and deployed in the study sites. Structured questionnaires were also administered to 184 respondents.

The study revealed that trypanosomiasis in camel caused by T. evansi appears to be more widespread and more prevalent in Marsabit than in Isiolo County.  The various species of biting flies were observed in all study sites in the two counties.  In all the two ASAL counties, there was no significant presence of tsetse and/or biting fly control technologies.  However, there was evidence of inappropriate use of drugs which may lead to infective control of the disease in camels and observed treatment failure. This needs to be addressed through appropriate training of the camel keepers and camel herders following identification of the most appropriate cost effective control strategies.
