*Only study sites where infected hosts were detected are included. Infection intensities were calculated by using eggs per gram of fecal samples for school-aged children and number of adult worms in rodents (M. huberti and A. niloticus). Infection intensity was not quantified for B. pfeifferi snails (intermediate host). NA, not applicable.
†For rodents, values include data previously reported (21).
