摘要
目的通过对一起新型冠状病毒肺炎(简称新冠肺炎)聚集性疫情的流行病学调查分析,探索新冠肺炎的发病原因和传播途径,为制定疫情防控策略和措施提供依据。方法对泸州市一起新冠肺炎聚集性疫情的流行病学调查资料、实验室检测结果以及疫情处理情况进行描述性流行病学分析。结果本起聚集性疫情确诊病例9例,男性6名,女性3名,主要为具有亲戚关系的一个大家庭成员;年龄平均39岁,最大68岁,最小5岁;职业以农民为主(6例,占66.7%),其次为待业及学生(2例,占22.2%)、工人(1例,占11.1%);临床表现以发热、干咳、流涕为主,发热5例,占55.6%,咳嗽5例,占55.6%,以干咳为主,流涕4例,占44.4%。危重症病例1例,重症病例2例,轻症病例6例;病例1-2为指示病例,均为武汉同车返泸人员,其中病例2引起了除1号病例外的病例3-7的发病,病例8-9为病例7引起的三代病例。结论本起疫情为一起以家庭成员或亲友聚集引起的聚集性疫情,早期发现和规范隔离治疗传染源、加强宣传提高公众疫情防控相关认知、减少人群聚集是控制聚集性疫情的重要措施。
