An analysis of the prevalence of Fasciolopsis buski in central Thailand using catalytic models. Amer J Epidem 93: 354–360, 1971.—Epidemiologic surveys for fasciolopsiasis were conducted in two Provinces in central Thailand and the age-specific prevalence data analyzed for fit to catalytic models, which substitute time for host age and employ separate rate constants for acquisition and nonreversible loss of parasites. Peak prevalence was found in subjects 10–15 years old; prevalence approached zero in old age. Little evidence could be found for a decreasing risk of infection with age, thus suggesting the development of acquired resistance as a more promising hypothesis.
