The number of snails infected with Schistosoma mansoni (SM), Schistosoma rodhaini (SR), unidentified mammalian schistosomes (US), and total schistosomes (TS) at various sites in the Lake Victoria Basin of Kenya.

The total number of snails collected, prevalence of schistosome infection (P), and prevalence of confirmed S. mansoni (SM P) and S. rodhaini (SR P) infections are given for each site. Prevalence for each species was also adjusted as denoted by an asterisk to accommodate unidentified schistosomes by multiplying the prevalence of schistosomes by the percentage of identified schistosomes for each species.
