摘要
目的了解浙江省并殖吸虫病流行现状。方法2005-2020年,在浙江省并殖吸虫病历史疫区每年选择1~2个县(市、区,以下简称县)的2~3个村开展监测,每个村选择当地居民50~150名作为监测对象,采集静脉血,使用酶联免疫吸附试验(ELISA)检测血清并殖吸虫抗体;每个村捕捉50~100只中间宿主溪蟹或蝲蛄,使用捣碎沉淀法检测并殖吸虫囊蚴感染情况。结果共对3297人进行血清学检测,并殖吸虫抗体阳性率为2.9%(94/3297);共检测溪蟹或蝲蛄3929只,分为2749组,其中790组检出囊蚴,囊蚴感染率为28.7%。结论浙江省部分县存在并殖吸虫传播链,仍具有并殖吸虫病流行的潜在风险。因此,需加大监测力度,广泛开展相关健康教育工作,以提高居民的自我防护意识。
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%(94/3297);3929 crabs or crayfish were divided into 2749 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.
