Results: A total of 9016 people were examined in 1 city of 9 counties, the infection rate was 6.96% ~ 66.85% with an average of 31.5%. Fifteen kinds of 416 fish were examined and 9 kinds of 255 fish were found infected with Clonorchis sinensis metacercaria, The infection rate of fish was 61.3%, and the infection rate of wild fish was the highest, reaching 100%. In addition to cats, dogs, pigs and other animals, sphingidae could also infect Clonorchis sinensis.
