Abstract:
Objective:To ascertain the endemic status of paragonimiasis in Zhejiang Province.Methods:From 2005 to 2020, 2-3 villages in 1-2 counties (cities, districts, hereinafter refferred to as counties) in historical endemic areas of paragonimiasis in Zhejiang Province were selected for monitoring each year. In each village, 50 to 150 local residents were selected as monitoring subjects, venous blood samples were collected, and serum Paragonimus antibody was detected by enzyme-linked immunosorbent assay (ELISA). Fifty to 100 intermediate hosts crabs or crayfish were collected in each village, and the infection of Paragonimus metacercaria was detected by crushing precipitation. Results:The positive rate of Paragonimus antibody was 2.9% (94/3 297); 3 929 crabs or crayfish were divided into 2 749 groups, 790 of which were found to have Paragonimus metacercaria infection, with a Paragonimus metacercaria infection rate of 28.7%. Conclusions:Paragonimus transmission chain exists in some counties of Zhejiang Province, which still has the potential risk of Paragonimus epidemic. Therefore, it is necessary to strengthen monitoring and carry out extensive health education to improve residents' self-protection awareness.
