2020年7-8月新疆乌鲁木齐市沙依巴克区新型冠状病毒肺炎流行病学特征分析

Epidemiological characteristics of COVID-19 in Shayibake district, Urumqi, Xinjiang, July–August 2020

  • 摘要:
      目的  分析2020年7 — 8月新疆乌鲁木齐市沙依巴克区(沙区)新型冠状病毒肺炎(COVID-19)的流行病学特征,为制定疫情防控策略提供科学依据。
      方法  以沙区报告发现的122例COVID-19病例为研究对象,回顾性描述沙区疫情概况、病例的三间分布、聚集性疫情特征及病例发现途径。
      结果  COVID-19病例122例,报告感染率为16.30/10万。 确诊病例106例(86.89%),无症状感染者16例(13.11%),男女性别比为1∶1.35。 其中维吾尔族病例占62.30%,汉族占35.25%。 年龄最小的为3月龄,最大的为92岁,中位年龄为33岁[四分位数间距(IQR):15~49岁]。 各年龄段均有病例,病例主要为<60岁人群(93/106,87.74%),无症状感染者主要集中在<40岁人群(15/16,93.75%),确诊病例平均年龄高于无症状感染者(35岁vs. 18岁,Z=−2.295,P<0.05)。 病例职业以学生为主(17.92%),其余依次为退休、无业、个体经营和服务人员。 聚集性疫情30起,涉及病例88例(72.13%),其中家庭聚集性疫情25起,病例73例(73/88,82.95%);邻里及单位聚集性疫情分别为2起,病例均为4例(4/88,4.55%);同班级聚集性疫情1起,病例7例(7/88,7.95%)。 疫情以家庭聚集性疫情为主。 长江管委会病例最多(26例,21.31%)。 通过集中隔离检测、居民大筛查、居家隔离检测发现113例,占92.62%,以主动检测发现为主。 疫情经过两个最长潜伏期得到有效控制。
      结论  沙区此次疫情传播迅速,以聚集性疫情为主,通过采取防控措施得到有效控制。

     

    Abstract:
      Objective  To analyze the epidemiological characteristics of COVID-19 cases in Shayibake district of Urumqi of Xinjiang and provide scientific evidence for the prevention and control of COVID-19 epidemic.
      Methods  A total of 122 cases of COVID-19 reported in Shayibake were studied. Descriptive investigations were conducted retrospectively to understand the age, gender and spatial/temporal distributions of the cases, the characteristics of clusters and the case detection ways.
      Results  A total of 122 COVID-19 cases were reported in Shayibake. The reported infection rate was 16.30/100 000. The 122 cases included 106 confirmed cases (86.89%) and 16 asymptomatic cases (13.11%). The male to female ratio of the cases was 1∶1.35. The cases in Uyghur population accounted for 62.30% and the cases in Han population accounted for 35.25%. The age of the cases ranged from 3 months to 92 years. The median age was 33 years (the interquartile range: 15–49 years). The cases were found in all age groups. The confirmed cases were mainly aged under 60 years (93/106, 87.74%), and the asymptomatic cases were mainly aged under 40 years (15/16, 93.75%). The average age of the confirmed cases was higher than that of the asymptomatic cases (35 vs. 18 years, Z=−2.295, P<0.05). The majority of the cases were students (17.92%), followed by the elderly retirees, the unemployed, self-employed persons, and service personnel. There were 30 clusters with 88 cases (72.13%). Among them, 25 were family clusters (73 cases, 73/88, 82.95%). There were 2 clusters in neighborhood and work place (4 cases, 4/88, 4.55%) and 1 cluster in the same class (7 cases, 7/88, 7.95%). Family clusters accounted for high proportion. There were 26 cases reported in Changjiang community, accounting for highest proportion (21.31%). A total of 113 cases (92.62%) were detected through centralized isolation, mass screening and self-isolation. Most of the cases were found through active detection. The outbreak was effectively controlled within two weeks, the longest latency periods.
      Conclusion  The epidemic of COVID-19 spread rapidly in Shayibake, mainly causing case clusters. The epidemic has been well controlled by effective prevention and control measures.
