2021年中国狂犬病流行特征分析

Epidemiological characteristics of rabies in China, 2021

  • 摘要:
    目的  分析2021年我国狂犬病流行分布特征,为防控策略的调整和制定提供科学依据。
    方法 收集“中国疾病预防控制信息系统”中2021年狂犬病疫情数据和国家级监测点数据,采用描述性流行病学方法发病率、发病时间、病例年龄等指标进行分析。
    结果  2021年全国有22个省(直辖市、自治区)报告病例157例,死亡150例,报告发病数较2020年(202例)下降22.28%。 狂犬病疫情主要分布在我国中部和南部地区,湖南省(50例)、河南省(22例)、江苏省(14例)和安徽省(12例),合计占全国报告发病总数的62.42%。 4、6、10月为全年发病最高月份,11月为全年发病最低月份。 病例以农民(84.00%)为主,男女性别比为2.74∶1,高于2020年(1.93∶1),各年龄组均有发病,以中老年病例居多(77.71%)。 77例病例个案分析显示,致伤动物以犬为主(91.67%),近70.00%致伤犬为自养犬或邻居家养犬,动物伤人的主要原因为主动袭击,潜伏期中位数为65(35.75, 221.75)d。 我国狂犬病病例实验室诊断率为22.93%。
    结论  2021年狂犬病疫情继续下降,自2007年以来持续保持下降的良好态势。 湖南省、河南省等地疫情相对严重,病例的实验室诊断率有待提高。

     

    Abstract:
    Objective To analyze the epidemiological characteristics of rabies in China in 2021 and provide evidence for the development and improvement of rabies prevention and control strategies.
    Methods The incidence data and national surveillance data of rabies in 2021 were collected from “China Disease Prevention and Control Information System” for a descriptive epidemiological analysis on the incidence rate of rabies, time distribution and age distribution of rabies cases.
    Results In 2021, a total of 157 rabies cases, including 150 deaths, were reported in 22 provinces (municipalities and autonomous regions) in China, a decrease of 22.28% compared with 202 cases in 2020. Rabies mainly occurred in central and southern China, the cases in Hunan (50 cases), Henan (22 cases), Jiangsu (14 cases), and Anhui (12 cases) provinces accounted for 62.42% of the total reported cases nationwide. The incidences of rabies were high in April, June and October, but low in November. The cases were mainly farmers (84.00%). The male to female ratio of the cases was 2.74∶1, higher than that in 2020 (1.93∶1). The cases were distributed in all age groups, but mainly in middle-aged and elderly people (77.71%). The analysis on 77 cases indicated that the animals biting people were mainly dogs (91.67%), but in these dogs, domestic dogs almost accounted for 70%, and active attack was the main way for the dogs in biting people. The median incubation period of the cases was 65 days (35.75, 221.75). The laboratory diagnosis rate of rabies was 22.93%.
    Conclusion The incidence of rabies continued to decline in China in 2021, has shown a downward trend since 2007. The disease situation in Hunan, Henan and other provinces was relatively serious, and the laboratory diagnosis rate of rabies cases needs to be further improved.
