Epidemiological studies on Ascaris lumbricoides reinfection in rural communities in Korea II. Age-specific reinfection rates and familial aggregation of the reinfected cases

摘要

Epidemiological studies on the reinfection pattern of Ascaris lumbricoides were undertaken by means of blanket mass chemotherapy and worm collection in a rural village in Korea, during 1977~1980. The study objectives were to determine the age(sex)-specific reinfection rate during 2, 4, 6 and 12 months through repeated mass chemotherapy with pyrantel pamoate, and to observe the familial aggregation tendency of the reinfected cases.
