Gambiense human African trypanosomiasis (HAT), or sleeping sickness, is a neglected tropical disease that has been targeted for elimination as a public health problem by 2020.1 Although this goal is challenging, it now seems achievable. Control efforts, sustained mainly by mobile teams who screen populations at risk with the Card Agglutination Test for Trypanosomiasis (CATT) and treat patients if confirmed by microscopic parasitological tests, have led to a rapid decrease in disease prevalence. Incidence passed below the symbolic number of 10 000 newly reported cases in 2009 and reached 7216 in 2012.
