摘要
目的分析2007-2013年宁陕县肾综合征出血热(HFRS)流行特征和规律,探讨鼠类汉坦病毒(HV)感染情况,为采取及时有效的预防控制措施提供科学依据。方法对2007-2013年宁陕县法定报告传染病年报表中HFRS疫情资料进行描述性统计分析并调查鼠类种群构成、密度及鼠血HV抗体阳性率。结果2007-2013年全县共报告14例HFRS病例,年均发病率为2.69/10万,死亡1人。发病最高年份为2011年,报告病例6例,发病率为8.07/10万,占5年报告病例总数的42.86%。本县肾综合征出血热发病有明显的季节性,夏季和冬季为高发季节。病例主要集中在210国道及京昆高速G5(西汉段)沿线乡镇。性别及职业特征明显,以农村男性壮年为主,男女性别之比为13∶1。野外优势鼠种为黑线姬鼠,居住区优势鼠种为黄胸鼠和褐家鼠;鼠血汉坦病毒特异性抗体IgG阳性率为25.89%(95/367)。结论针对该病流行环节做好重点人群防控工作,减少HFRS的危害。宁陕县感染HV的鼠类多样,感染率高,因此需进一步加强疫情监测、防治和深入研究工作。
Objective To analyze the epidemic feature and regulation of HFRS in 2013 in Ningshan county and to discuss the infection situation of murine HV,to provide the scientific basis for efficient prevention and control measures.Methods Descriptive analysis was used in official epidemic report of HFRS from 2007 to 2013 in Ningshan county.Rodent species composition,rodent density and HV antibody positive rate of blood were surveyed from 2007 to2013.Results 14 HFRS cases were reported from 2007 to 2013 in this county,average annual morbidity was 2.69 per 100 thousand,and 1 death was found.The highest morbidity occurred in 2011 with 6 cases reported,and the morbidity was 8.07 per 100 thousand,accounting for 42.86% of the total number of reported cases for 5 years.The epidemic of HFRS in the county revealed obvious season-relation,most in summer and winter.Cases mainly occur in the villages and towns along G210 and G5 highway.The epidemic of HFRS also held gender and occupation characteristics.Rural male adults were the main object and the ratio of male to female was 13 ∶ 1.Dominant field rodent was Apodemus agrarius,dominant residential rodent were Rattus tanezumi and Rattus norvegicus; specific antibody IgG positive rate of blood was 25.89%（95/367）.Conclusion Disease prevention and control work should be strengthened according to the popular aspects of the disease for reduceing the damage of HFRS.The monitoring of the epidemic,prevention and research work should be further strengthened because of HV infected rodent species diversity and high infection rate in Ningshan county.
