目的了解安义县2009年肾综合征出血热(hemorrhagic fever with renal syndrome,HFRS)的流行特征,为防治提供科学依据。方法对安义县2009年HFRS疫情及宿主动物监测资料进行分析。结果 2009年安义县HFRS发病率5.47/10万,无死亡病例。病人以青壮年农民为主。捕获鼠类7种240只,其中居民区鼠密度为7.99%,以小家鼠、黄胸鼠为优势鼠种;野外鼠密度为7.61%,野外鼠以黑线姬鼠、黄毛鼠为优势鼠种。鼠带毒率为0.83%,均检自野外鼠黑线姬鼠,鼠血总抗体阳性率为4.58%。结论安义县HFRS发病上升较快,加强疫情监测,大力开展灭鼠工作,提高人群免疫力,控制HFRS的发病率回升。
Objective To understand the epidemiological characteristics of hemorrhagic fever with renal syndrome (HFRS) in 2009 in Anyi County and provide a scientific basis for prevention and treatment. Methods The epidemic situation of HFRS in 2009 in Anyi County and host animal monitoring data were analyzed. Results In 2009, the incidence of HFRS in Anyi County was 5.47 / 100 000 with no deaths. The patients are mainly young farmers. 240 species of rodents were captured in 7 species, of which 7.99% were rodents inhabited by rodents. The dominant species were Mus musculus and Rattus flavipectus. The density of wild rodents was 7.61%. The dominant species were Apodemus agrarius and Rattus flavipectus Mouse species. The rate of rodent infection was 0.83%. Both were detected from the wild rats Apodemus agrarius, the positive rate of rat blood total antibody was 4.58%. Conclusion The incidence of HFRS increased rapidly in Anyi County. The surveillance of epidemic situation was strengthened. The anti-rodent work was vigorously carried out to enhance the population immunity and control the incidence of HFRS.
