摘要 目的 分析2020年3月1日—4月7日浙江省境外输入新型冠状病毒肺炎(COVID-19)病例流行特征,为完善COVID-19境外输入疫情防控工作提供依据。方法 通过中国疾病预防控制信息系统收集2020年3月1日—4月7日浙江省境外输入COVID-19病例及境外输入关联本地病例资料,结合现场流行病学调查资料,对境外输入COVID-19病例的时间分布、地区分布、人群分布、临床分型、输入来源及境外输入关联本地病例接触史等流行特征进行分析。结果 3月1日浙江省报告首例境外输入COVID-19病例,截至4月7日累计报告91例,其中确诊病例48例,占52.75%;无症状感染者43例,占47.25%。确诊病例中普通型32例,占66.67%;轻型16例,占33.33%;无重型、危重型病例报告。无死亡病例报告。确诊病例中,入境后发病41例,入境至发病间隔时间中位数为3 d,其中4例间隔时间≥14 d。浙江省11个市均有境外输入病例报告,丽水市和温州市报告较多,分别为24例和21例,占26.37%和23.08%。病例年龄以10~49岁为主,81例占89.01%;职业以留学生、商业服务人员和餐饮食品业人员为主,分别为31例、21例和19例,占34.07%、23.08%和20.88%。69例境外输入病例来自欧洲国家,占75.82%,以意大利、英国和西班牙为主。3月26日报告1例与境外输入COVID-19病例乘同一国内转机航班的境外输入关联本地确诊病例。结论 浙江省境外输入COVID-19病例相对年轻,以无症状感染者及普通型居多;集中于丽水市和温州市,以留学生、商业服务人员和餐饮食品业人员为主;主要来自意大利、英国和西班牙等欧洲国家。对所有入境人员在入境检疫、转运和隔离观察等环节应实行全程严密管控,防止输入疫源引起本地传播。

AbstractObjective To learn the epidemiological characteristics of imported coronavirus disease 2019(COVID-19)cases from abroad to Zhejiang Province reported from March 1 to April 7,2020,so as to provide basis for improving the prevention and control of COVID-19 imported epidemic. Methods The imported COVID-19 cases and related local cases reported in Zhejiang Province from March 1 to April 7 were extracted from the National Diseases Prevention and Control Information System and were checked with the epidemiological investigation reports. A descriptive analysis was adopted for the epidemiological characteristics of imported COVID-19 cases,including time,spatial and population distribution,clinical classification,country of origin and contact history of related local cases. Results The first imported COVID-19 case was reported on March 1. By April 7,totally 91 imported cases were reported,including 48(52.75%)confirmed cases and 43(47.25%)asymptomatic cases. In terms of clinical classification,there were 32(66.67%)ordinary cases and 16(33.33%)mild cases;no severe,critical or dead cases were reported. The symptoms of 41 confirmed cases came out after entry. The median time between entry and onset was 3 days,and the intervals of 4 cases were 14 days or over. All the 11 cities in Zhejiang Province had imported cases,among which Lishui and Wenzhou reported 24(26.37%)and 21(23.08%)cases. Of all the imported cases,81(89.01%)aged from 10 to 49 years;31(34.07%)were overseas students,21(23.08%)were business people and 19(20.88%)were catering staff;69(75.82%) came from European countries such as Italy,UK and Spain. In addition,a local case on the same flight with a imported case was reported on March 26. Conclusions The imported COVID-19 cases of Zhejiang Province were relatively young,most were asymptomatic or ordinary cases. They were mainly overseas students,business people and catering staff,from European countries such as Italy,UK and Spain,to Lishui and Wenzhou. Strict control measures should be done in entry quarantine,transfer and isolation to prevent local transmission caused by imported cases.
