Abstract:
Objective To understand the epidemic status of clonorchiasis and awareness of prevention and control knowledge in Xinfeng County of Jiangxi Province, so as to provide the evidences for control measures. Methods The baseline survey was carried out with a clue in vestigation of raw-fish eating behavior in potential endemic areas in 2016.The residents were examined by stool tests. The metacercariae of Clonorchis sinensis in fish, the rediae and cercariae in freshwater mollusk were detected. The feces samples of cats, dogs and pigs were collected and examined by sedimentation technique. Meanwhile, the epidemic factors, health knowledge and behavior were also surveyed. Results The residents in 26 villages had the habit of eating raw freshwater fish, and 19.51% of the respondents had this habit. The average infection rates of the population, Parafossarulus striatulus, freshwater fishes and reservoir hosts were 21.56%, 0, 8.24% and 2.27%, respectively. The infection rate of the population increased with age. There was a significant positive correlation between the behavior and the infection rate of the population (r = 0.88, P < 0.01). Only 11.46% of the respondents knew that eating raw-fish might cause C. sinensis infection, and 5.28% of them knew that C. sinensis was harmful to health. Conclusions Twenty-six villages in five townships were endemic areas of clonorchiasis in Xinfeng County. The permanent solution of prevention and control of clonorchiasis is to strengthen the health education and change the habit of raw-fish eating gradually.
