Rationale for Gambian HAT

Current low levels of HAT is the opportunity to push for its elimination. • Case detection and treatment does not prevent infection. • Coverage is only 75%. • Low sensitivity of diagnostic tests. • Residual levels of infection remain in communities to sustain transmission. • Animal reservoirs may play a larger role than previously thought. • Traditional vector control seen as too expensive in resource-poor settings. • Availability of “tiny insecticide impregnated targets” is cost-effective. • Riverine tsetse concentrate near lakes or rivers.
