RESUMO
OBJECTIVE: To evaluate the effect of control on soil-transmitted nematode infections in the demonstration plot of integrated control on parasitic diseases, Hainan Province. METHODS: The plot (county) was divided into east, west, north, south and central areas and the villages in these areas were selected with the random sampling method, and then the residents in these villages were investigated with Kato-Katz technique for soil-transmitted nematode infections and with questionnaires for knowledge, attitude and practice (KAP) and so on before and after the implementation of the control measures. All the results were analyzed and compared statistically. RESULTS: Compared with the results of the baseline survey, the overall infection rate of soil-transmitted nematode decreased by 68.66%. The infection rates of soil-transmitted nematode in the male and female decreased by 69.56% and 67.73%, respectively, and the rates in the children and adults decreased by 70.51% and 68.09%, respectively. The infection rates of Ascaris lumbricoides, Trichuris trichiura and hookworm decreased by 95.87%, 90.00% and 65.22%, respectively. The awareness rate of health knowledge increased by 115.23% and the qualified rate of health behavior increased by 51.61%. CONCLUSION: The remarkable results of soil-transmitted nematodiasis control have been achieved in the demonstration plot of integrated control on parasitic diseases, Hainan Province.
