OBJECTIVE: To understand the status of soil-transmitted nematode infections in Xiding Township, Menghai County, Yunnan Province, so as to provide the reference for formulating the strategy of soil-transmitted nematodosis control.
METHODS: Soil-transmitted nematode eggs in feces were detected by the Kato-Katz method, and the eggs of Enterobius vermicularis were detected by the cellophane tape method in children. The soil samples were collected from vegetable, fruit and other crop fields of 15 residents randomly to detect hookworm.
RESULTS: The stool samples from 1 002 residents were examined and the soil -transmitted nematode infection rate was 20.06% (201/1 002). The infection rates of hookworm, Ascaris lumbricoides and Trichuris trichura were 18.96% (190 cases), 1.70% (17 cases) and 0.90% (9 cases) respectively. The percentages of people with light infection of hookworm, A. lumbricoides and T. trichura were 97.37% (185/190), 88.24% (15/17) and 100% (9/9) respectively. No infection of E. vermicularis was found. Fifteen soil samples were tested, and no hookworm was found in the soil.
CONCLUSIONS: The infection rate of soil-transmitted nematode in Xiding Township, Menghai County is high, but the infectiosity is light. The control and monitoring of soil-transmitted nematodosis should be strengthened in this area.
