[Investigation on Clonorchis sinensis infection and its risk factors in Futian District, Shenzhen City].

OBJECTIVE: To understand the status of Clonorchis sinensis infection and its risk factors in Futian District, Shenzhen City, so as to provide the evidence for formulating the strategy of prevention and control. METHODS: Two monitoring points were randomly selected, and the permanent population aged ≥ 3 years were investigated and their stool samples were detected for the eggs of C. sinensis by using Kato-Katz technique. Meanwhile, the risk factors of infection were also investigated. RESULTS: A total of 743 subjects were examined, and 7 persons were infected with C. sinensis and the infection rate was 0.94%. Most of the infected cases were focused on 20-40 and 40-60 age groups. The risk factors were eating raw or semi-cooked fish, and the protective factor was the use of separated cutting board for cooked or uncooked food. CONCLUSION: The infection rate of C. sinensis is low in the population of Futian District. However, the health education, especially for diet health education, still should be strengthened.
