[Longitudinal observation on the control of intestinal helminthiasis].
OBJECTIVE
To search suitable measure for rapid control intestinal helminthiasis and long-term strengthen efficacy.

The treatment was taken in egg-positive population of intestinal helminthiasis in 1986-1988. The treatment was carried out only in the selected population in 1989-1992. No measure was taken in 1993-2000.


RESULTS
(1) The prevalence rate of hookworm, Ascaris and Trichuris decreased to 3.2%, 37.3% and 3.5% respectively after administration of albendazole twice a year for 3 years. (2) The prevalence rate of hookworm continued to decrease to 0.5% after treatment on selected population.
