摘　　要：目的探索家庭聚集性新型冠状病毒肺炎(COVID-19)疫情的影响因素,为防控家庭聚集性疫情提供科学依据。方法分析截至2020年2月18日乌鲁木齐市家庭聚集性确诊COVID-19病例流行病学特征,包括病例特征、时间与地区分布、临床表现、流行病学史及传播因素等。结果乌鲁木齐市发生COVID-19聚集性疫情6起、确诊病例23例,其中家庭聚集性5起、发病17例,其中一代病例5例、占聚集性总病例的29.4%,4例为输入型;二代密切接触续发病例12例、占聚集性总病例的70.6%,平均续发率为7.2%;临床主要表现为发热11例、占64.6%,其次为咳嗽与咳痰6例、占35.3%,腹泻病人最少(1例)、占5.9%;发病高峰在1月31日;高新区病例最多(8例)、占47.1%,沙依巴克区其次(6例)、占35.3%,水磨沟区病例最少(3例)、占17.6%;40岁及以上病人数最多(11例)、占64.6%;以干部职员为主(4例)、占23.5%。结论此次乌鲁木齐市新冠肺炎病例主要呈聚集性发病,且以家庭聚集性为主,主要原因是隔离措施不到位;今后疫区返疆人员应进行集中医学隔离观察,并做到单人单间隔离,隔离期间禁止与他人接触,且按规范做好医学隔离区域的消毒工作。Objective To explore the influence factors of family clustering of novel coronavirus pneumonia(COVID-19),and provide scientific basis for prevention and control of the family clustering epidemic.Methods The epidemiological characteristics of family clustering cases of confirmed COVID-19 were analyzed in Urumqi by the end of February 18,2020,including characteristics of the cases,time and region distribution,clinical manifestations,epidemiological history and factors of transmission,etc.Results There were 6 clustering epidemics of COVID-19 occurred in Urumqi,with 23 confirmed cases,including 5 epidemics of family clustering,with 17 cases involved.Out of the 17 cases,5 cases were first-generation,accounting for 29.4%of the family clustering cases,and 4 cases were imported.There were 12 cases were second generation with close contact history,accounting for 70.6%of the family clustering cases,with the average recurrence rate of 7.2%.The main clinical manifestations were fever(11 cases,accounting for 64.6%),followed by cough and sputum(6 cases,occupying35.3%),only 1 case had diarrhea,holding 5.9%.The peak of onset was on January 31.Most cases located in the high-tech zone(8 cases),accounting for 47.1%,followed by Shayibake district(6 cases,35.3%),and the least distributed in Shuimogou district(3 cases,17.6%).There were 11 cases aged 40 years and elder,accounting for 64.6%,and 4 cases of cadres and staff,holding 23.5%.Conclusions The cases of COVID-19 mainly display clustering onset,especially the family clustering in Urumqi.The main reason is that the isolation measures are not strictly implemented.Afterwards,all people returning Xinjiang from the epidemic area should be gathered for medical isolation and observation.One person must be isolated in one room for centralized medical isolation,and the isolating people are prohibited to contact others,and the disinfection should be carried out according to the regulation in the medical isolation zone.
