Individual locations are shown on Fig. 1. Samples from Nouakchott were from three different health facilities, and proportions of species at each of these are shown in Table 2
aRelative proportions of each species at each site are estimated by counting numbers of infections with each species, with each being counted separately from mixed species infections
