摘要
目的了解浙江省并殖吸虫病流行现状,为制订切实可行的防治策略提供依据。方法采用问卷调查方式调查村民有无半生吃或生吃溪蟹史等；采集4县部分村的淡水蟹类检查并殖吸虫囊蚴感染情况；对9个村的部分人群作并殖吸虫成虫抗原皮内试验,采血ELISA法检测并殖吸虫抗体。结果问卷调查发现村民生吃蟹率为37．66%；解剖的溪蟹中,囊蚴感染率为7．93%；庆元及景宁县并殖吸虫皮试阳性率为15．94%和2．27%,人群抗体阳性率为0,80%和2．27%,天台和绍兴县人群抗体阳性率为0和14．29%。结论浙江省并殖吸虫病老疫区流行情况变化较大,需定期进行流行病学调查及监测。
Objective To provide scientific basis for planning of prevention and control through the understanding of the prevalence of paragonimiasis in Zhejiang Province.Methods The crab eating habits of the inhabitants were studied by in- vestigation table.We dissected the crab to determine the situation of the crab infected by metacercaria.Intradermal test and ELISA were used to examine part of the population in nine villages.Result Eating raw crab rate was 37.66% according to the investigation table,metacercaria infection rate was 7,93% in dissected crabs.Positive rates of intradermal test were 15.94% and 2.27%,and antibody(Ab)positive rates of the population were 0.80% and 2.27% respectively in the counties of Qingyuan and Jingning.Ab positive rates of the population were 0 and 14.29% in the counties of Tiantai and Shaoxing. Conclusion The prevalence situation has changed in the old prevailing area of Zhejiang Province.Regular check-up and surveillance of epidemiology should be warranted.
