*HAT, human African trypanosomiasis; YLL, years of life lost; YLD, years lived with disability; DALYs, disability-adjusted life years.
†Discount rate = 0.03; age weighting factor = 0.04; age weight modulating factor =1; DALYs with intervention = 16 (YLD) + 721 (YLL) = 737; DALYs without intervention = 40 (YLD) + 2104 (YLL) = 2,144.
