Distribution of the snails Bulinus globosus and Bulinus nasutus productus across 73 sites south-east of Lake Albert in Uganda sampled in October and November 2020. The maroon-coloured circles indicate locations where B. globosus was found, the green-filled circles represent the location of the Tuhumwire site where B. nasutus productus was found. The size of the circle represents the total number of snails collected. The locations where Schistosoma haematobium was previously reported [21] are indicated by green rectangles with dashed outlines. Schistosoma haematobium has also been reported in neighbouring countries, including the Democratic Republic of Congo, South Sudan, Kenya and Tanzania
