2013-2017年青海省玉树藏族自治州牧区狂犬病流行特征分析

Epidemiological characteristics of rabies in pastoral areas in Yushu, Qinghai, 2013−2017

  • 摘要: 目的调查2013 — 2017年青海省玉树藏族自治州(玉树州)牧区狂犬病流行特征,为牧区狂犬病的防控提供依据。方法收集玉树州2013 — 2017年狂犬病疫情监测资料及一犬(动物)伤多人事件调查表并进行统计分析。结果共报告犬伤人事件252起,确诊狂犬病死亡病例5例。 年均犬伤人事件63起,发病率为1.98/10万,死亡率为100%。 发病死亡时间较短(平均3 ~ 4 d),而伤及下肢距心脏较远的部位发病潜伏较长。 人脑组织、狼脑组织和牛脊髓狂犬病病毒检出率均为100%。 一犬伤多人事件5起,波及16人,其中流浪犬伤人死亡4例。家犬伤人死亡1例。 Ⅱ级暴露人员处置11例。经及时处理过的Ⅱ级暴露人员均未发病,犬伤人主要以11月至次年4月发生最为频繁。结论2013 — 2017年玉树州牧区狂犬病疫情呈上升趋势,狂犬病野生宿主与家畜、人类生产生活密切接触频率大大增加,犬的管理不到位和暴露后规范处置率低是狂犬病发病的主要原因。

     

    Abstract: ObjectiveTo analyze the monitoring data of rabies in the pastoral areas of Yushu prefecture, Qinghai province, from 2013 to 2017, discuss the epidemiological characteristics of rabies and provide evidence for the rabies prevention and control in pastoral areas.MethodsThe surveillance data of the rabies in Yushu from 2013 to 2017 were collected and analyzed and the information about dog biting were collected by using questionnaire.ResultsFrom 2013 to 2017, a total of 252 cases of dog biting were reported in Yushu, and 5 confirmed rabies cases occurred in 2 males and 3 females. Averagely, 63 dog biting cases occurred each year. The incidence was 1.98/100 000, and case fatality rate was 100%. The interval between onset and death was short (averagely 3–4 days). The incubation period was longer in cases with biting on lower limbs. The detection rates of rabies virus in human and wolf brain samples and cattle spinal marrow samples were all 100%. Of 5 rabies cases, 4 died within 1–7 days after exposure, and 1 died after 7 days of exposure. In addition, 5 cases of one dog biting multi people were reported, involving 16 persons and causing 5 deaths (4 deaths after street dog bite, 1 death after domestic dog bite). All the 11 persons who had grade Ⅱ exposure survived due to timely post exposure treatment. Dog biting mainly occurred during November–April.ConclusionFrom 2013 to 2017, the incidence of rabies in the pastoral areas of Yushu was in increase. The frequency of close contact between the wild host of rabies and livestock and human greatly increased. The poor management of dogs and low standard post exposure treatment rate were the main reasons for the increased incidence of rabies.
