[Objective] To understand the changes of human parasites in Guangdong Province in the last 10 years and the effects of insecticides on intestinal nematodes. [Methods] According to the survey method of human parasite distribution throughout the country. [Results] The infection rate of the second human parasite was 48.1%, which was 33.3% lower than the first 72.1%. Hookworm, roundworm and whipworm decreased by 70.6%, 58.7% and 45.1% respectively. %; while Clonorchis sinensis increased by 12 4.0 %. The infection rate in Kaiping County, where collective drugs were repelled, dropped from 54.0 percent to 27.0 percent, while the unscheduled Dengbai County increased from 70.7% to 84.7%. 38 species of insects were detected this time. Among them, the giant schistosomiasis, the nematode, and the rosary spines were reported for the first time in our province. [Conclusion] In the past 10 years, Guangdong Province has systematically carried out insect repellents and the human parasites have been significantly reduced, especially the soil-infected nematodes such as roundworms, hookworms, and whipworms. The infection of Clonorchis sinensis was on the rise due to the increase in the number of people eating fish.
