Results The average infection rate of Clonorchis sinensis was 16.30% in Jiangmen urban area, of which the infection rate was the highest in 50 ~ The infection rates of the first and second intermediate hosts were 0.24% (7/2921) and 6.94% (5/72), respectively. The total dose of praziquantel by 80mg / kg, 2d points service, can obtain satisfactory results. Conclusion The urban area of Jiangmen is still a moderate endemic area of Clonorchiasis sinensis.
