[Investigation of intestinal nematode infections in Hongze County, Jiangsu Province].
OBJECTIVE
To understand the situation of intestinal nematode infections and assess the preventive effects, so as to provide the evidence for formulating the further measures of prevention.


METHODS
Five villages from 5 townships of different geographical locations were selected and 500 residents of each village were surveyed. The eggs of intestinal nematodes were detected by the Kato-Katz technique, and 50 students and 50 residents per village were investigated by questionnaires about health education.


RESULTS
Among 3 011 people detected, 17 persons were infected with intestinal nematodes and the total infection rate was 0.56%. The rates of Ascaris lumbricoides, hookworm, Trichuris trichiura, Enterobius vermicularis, and Trichostrongylus were 0.10%, 0.33%, 0.03%, 0.03% and 0.07%, respectively. The awareness rate of health knowledge was 97.80% and the formation rate of health behavior was 97.00%.


CONCLUSIONS
The infection rates of intestinal nematodes, the awareness rate of health knowledge and the formation rate of health behavior in the population of Hongze County have achieved the criteria of effective control of intestinal parasitic diseases.
