2009年安义县肾综合征出血热监测研究

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。

Surveillance of hemorrhagic fever with renal syndrome in Anyi County in 2009

Objective To find out the epidemic characteristic and trend of renal syndrome hemorrhagic fever （HFRS） and provide the scientific basis for prevention and control of this disease. Methods The HFRS surveillance data of human epidemic situation and the host animals in Anyi County in 2009 was collected and analyzed. Results In 2009,cases of HFRS were reported in Anyi County. The human incidence rate of HFRS was 5.47 per 100 thousand,no death case. Most of the patients were young farmers. 240 rats belong to 7 species were caught. The density of rat in residential area was 7.99%; the dominant species were Rattus flavipectus and Mus musculus. And the density of rat in field was 7.61%,the dominant species were Apodemus agrarius and Rattus losea. The rate of rat with virus was 0.83%,which all came from Apodemus agrarius living in field. The positive rate of the total antibody in rat blood was 4.58%. Conclusions The incidence rate of HFRS increased quickly in Anyi County during 2009. It is essential to strengthen the epidemic surveillance,carry out ＂anti-rat＂ movement,and improve public immunity to control the raise of human incidence rate of HFRS.
