Abstract:
Objective To evaluate the methods in early warning of schistosomiasis and elimination of snails in an ecological public forest in Yexie Town of Songjiang District, and provide the basis for monitoring and controlling snails in forest land in the future. Methods The monitoring data of snails, schistosomiasis and snail elimination in the public forest were collected to evaluate the effect of controlling snails. Results The area with existence of snails was found to be 10.47 hm2, and it was decreased by 98.28% after three times of snail elimination.A total of 1 904 serological tests was performed (test rate of 88.76%) with the positive rate of 0.16%.Pathogenic test result was negative in 3 subjects examined.Serological samples of 11 dogs and 1 sheep were all negative for the test.None of the 1 480 live snails tested was found to be positive in infection.The awareness rate of schistosomiasis control knowledge and behavior formation in 275 students were 98.2% and 95.3%, respectively. Conclusion The snails in the public forest in Yexie Town have been effectively controlled, but there are still scattered living snails.The measures in eliminating and monitoring of snails should be continued and strengthened.
