Abstract : Manson's schistosomiasis in Puerto Rico affects about 20% of the population. The clinical significance of infection among Puerto Ricans in its environment is being studied in cases seen at the University Hospital. A total of 2,546 cases has been analyzed. All of these are well proven cases of the disease. The diagnosis has been proven by the demonstration of ova either by stool examination or by tissue examination, mainly rectal biopsy. Most cases had multiple exposures to infected water. Since in most instances the initial infection as well as the subsequent disease is asymptomatic, in these series the time of infection has been taken as the time of initial exposure to contaminated water. Since the main reason of exposure to infected water in Puerto Rico is for pleasure, it must be said that; as a general rule, the disease is not as severe as in other countries where people are forced to work in contaminated water. In eighty cases of these series the patients consistently denied exposure to streams or stagnant water.
