Abstract:

Objective To understand the epidemic dynamics of intestinal nematodiasis in Wujiang City. Method The resi? dents of Yinghu Village of Wujiang City were investigated with Kato?Katz technique for the infections of intestinal nematodes，and the persons with the infections were administered with anthelmintics and they also received the health education. Results Of the 5 757 residents，147 persons were infected with intestinal nematodes，with the average infection rate of 2.55%. The infection rates of hookworm，Ascaris lumbricoides and Tricuris trichiura were 1.96%，0.49% and 0.24%，respectively. The repeated infec? tion rate was 20.30%， that was 10.36 times higher than the new infection rate（1.96%） .
