[Surveillance of intestinal nematode infections in Nanjing City from 2008 to 2012].

OBJECTIVE: To understand the intestinal nematode infection status of Nanjing City, so as to provide the evidence for formulating the preventive strategy and measures. METHODS: The eggs of intestinal nematodes were detected by Kato-Katz technique in population and eggs of Enterobius vermicularis were detected in children and low-grade primary school students by the transparent adhesive tape anal swab method. RESULTS: The fecal specimens from 45,645 individuals were tested, and of those, 167 were found to be infected with intestinal nematodes. The total infection rate was 0.36%, and the infection rates of Ascaris lumbricoides, hookworm, and Trichuris trichiura were 0.18%, 0.03%, and 0.15%, respectively. Totally 43,356 children and low-grade primary school students were surveyed for Enterobius vermicularis infection, and the infection rate was 0.31%. CONCLUSION: The prevalence of intestinal nematodes of population is low in Nanjing City. However, we still need to strengthen health education and regular monitoring.
