Abstract

The “Stamp Out Sleeping Sickness” programme, which was launched in 2006, aimed to halt northward spread of T. b. rhodesiense sleeping sickness by mass trypanocidal treatment of the cattle reservoir. Phase 1 targeted the most northerly of the districts newly affected by T .b. rhodesiense sleeping sickness in Uganda. Post treatment monitoring revealed a cluster of villages in which T. b. rhodesiense remained present in the cattle reservoir. They were located close to one another and within parishes that continued to report human sleeping sickness cases, indicating the transmission cycle may not have been properly interrupted in these areas. As a result, re-treatment of these high risk areas was proposed.

This study aims to assess the impact of the SOS re-treatment intervention on the prevalence of T. vivax, T. b. brucei and T. b. rhodesiense by analyzing cattle blood samples from 20 randomly selected villages within the re-treatment area, 10 of which are to be human sleeping sickness case villages and 10 of which have no reported human sleeping sickness cases. Samples have been taken immediately before and 6 months post re-treatment, and will be subjected to PCR based methods for the detection of parasite DNA.

This poster will review the results of the SOS re-treatment surveillance samples, and their implications both for the SOS programme and for the Epidemiology of trypanosomiasis in Uganda as a whole. The case control aspect of the follow up study allows for the comparison of trypanosome prevalence in villages known to have reported human sleeping sickness cases between January and July 2007 and those that did not.
