目的持续观察肾综合征出血热(HFRS)高发疫区的控制情况。方法收集金华市婺城区沙畈乡5个村HFRS疫情数据,对开展灭鼠防鼠、免疫接种等综合防控工作的效果进行分析评价。结果灭鼠前后进行鼠密度测定,室外鼠密度从6.00%(18/300)下降到1.70%(5/300);室内鼠密度从7.00%(7/100)下降到4.81%(5/104);1997年沙畈乡5个村发病率490.23/10万。对从事野外劳动的16~60岁农民实施疫苗接种,免疫覆盖率达51.86%,免疫阳转率为97.60%,1999—2013年仅1例未接种者发病。结论以疫苗接种为主,辅以灭鼠等防制措施,对HFRS高发疫区的控制效果满意。
Objective To observe continuously the control of HFRS epidemic area. Methods The data of HFRS epidemic in 5 villages in Shacheng Township, Wucheng District, Jinhua City were collected and the effects of rodent prevention and rodent control and immunization were analyzed and evaluated. Results Rat densities were measured before and after decontamination. The density of outdoor rats decreased from 6.00% (18/300) to 1.70% (5/300). The density of indoor rats decreased from 7.00% (7/100) to 4.81% (5/104) In 1997, the incidence rate of 5 villages in Shajiao Township was 490.23 / 100,000. Vaccination of 16 to 60-year-old peasants working in the field was conducted with an immunization coverage of 51.86% and an immunopositive rate of 97.60%. Only 1 case of unvaccinated individuals was infected in 1999-2013. Conclusions Vaccination is the main method, supplemented by deratting and other control measures, the control effect of high incidence area of HFRS is satisfactory.
