Analysis the Epidemiological Characteristics of 43 Family-clustered COVID-19 in Ningxia

目的分析宁夏家庭聚集性新型冠状病毒肺炎(简称新冠肺炎)患者的流行特点,为该地区制定疫情防控工作措施提供参考依据。方法收集2020年1月27日至3月16日宁夏43例家庭聚集性新冠肺炎确诊患者的临床资料,应用三间分布描述其流行特点。结果宁夏43例家庭聚集性新冠肺炎确诊患者,涉及16户家庭(族),占全区患者总数的57.3%。家庭聚集性患者以吴忠市居多,占55.8%。发病高峰出现在2月9—12日,2月10日和12日单日发病数最高。21~59岁年龄组患者31例。患者以农民居多,占27.6%。临床分型以普通型为主,占70.0%。家庭聚集性和非家庭聚集性患者的年龄、临床分型分布差异均无统计学意义(P均>0.05)。结论防止家庭聚集性新冠肺炎患者发生,需完善和规范各类风险等级地区的防控标准和要求,中、高风险地区应严格执行高危人群和密切接触者隔离制度,坚决禁止人群聚集性活动,科学合理地开展社区、乡村防控工作。
