Objective To understand the Clonorchis sinensis infection situation of freshwater fish and shrimp in Shaoguan city, and the public's awareness and prevention awareness of Clonorchiasis , we provide scientific basis for the relevant departments of Shaoguan City to carry out the prevention and treatment of Clonorchiasis . Methods The questionnaire survey about the prevention and control awareness of clonorchiasis was carried out through the network. The samples of freshwater fish / shrimp were collected from four areas in Shaoguan city from May 2018 to November 2018, and metacercaria of Clonorchis sinensis were detected by tissue compression method. SPSS 21.0 software was used to process and analyze the data. Results The total detection rate of metacercariae of Clonorchis sinensis was 29.55%. The detection rate of freshwater fish (1.78%) was lower than that of freshwater shrimp (58.70%) ( P <0.01). There was a significant difference ( P <0.05) in the detection rate of metacercariae of Clonorchis sinensis among the four area in Shanguan. The highest detection rate was Renhua area (37.50%). The detection rate of fresh water fish / shrimp in the market (39.96%) was higher than that in the wild (2.20%). There was a significant difference between market and wild ( P <0.01). The public's awareness rate of Clonorchis sinensis was 67.35%, and there were statistical differences in the awareness rate among different age groups and different education levels, which were ( χ 2 = 19.411, P <0.05) and ( χ 2 =39.624, P <0.05). The history of eating “Sashimi” was 25.77% (101 persons), and the active susceptible group was 30.87%. Conclusion Freshwater fish and shrimp in some areas of Shaoguan City have a certain degree of Clonorchiasis infection.
