Of 196 serum samples collected in 1977 in San Juan, Puerto Rico, 27 (13.8%) were positive for antibodies to Schistosoma mansoni eggs by the circumoval precipitin test. No sex differences were observed. The highest positivity (33%) occurred in the 20- to 29-year-old group. 116 of the samples collected came from residents of San Juan and Rio Piedras, of whom 16.4% (19) were positive. Although the sample size was small the results suggest that infection with S. mansoni may be more widespred in Puerto Rico than is generally believed.
