30日三亚市某酒店方舱医院收治的新型冠状病毒感染者的流行病学资料,进行描述性流行病学分析。结果:截至2022年 8月 30日,该酒店方舱医院共收治新型冠状病毒肺炎感染者 703例,其流行病学特征分析结果显示:男性 328 例,占 46.7%,女性 375 例,占 53.3%,男女比例 0.87 1,年龄跨度为 8 个月85 岁,M(P25,P75)为 37(20,49)岁,以 3159岁人群为主,占 51.4%;无症状感染者占 39.8%,轻型感染者占 60.2%,主要临床症状为咳嗽 24.8%(105/423)、发热 18.7%(79/423);8.8%的感染者有慢性基础疾病史,高血压和糖尿病最常见;累计出院 416例感染者,总体住院时间的 M(P25,P75)为 14(10,15)d;未接种 COVID-19疫苗者占 10.1%,完成 1次疫苗接种者占 5.0%,完成 2次疫苗接种者占 36.3%,完成 3次疫苗接种者占 48.6%,60岁感染者中完成2次和 3次疫苗接种的仅占 10.1%和 8.8%。结论:此次毒株为新型冠状病毒奥密克戎变异株 BA5.1.3,国内首次报道,传染性和隐匿性更强,各年龄段人群普遍易感。因此需要加强个人防控,做好外防输入和内防扩散;加强核酸检测,做到及时发现和早期处理;加强 COVID-19 疫苗接种工作,提高疫苗接种率,减少感染率。关键词 新型冠状病毒;新型冠状病毒肺炎;流行病学特征;方舱医院;海南中图分类号 R181.3;R563.1 文献标识码 A 文章编号 1007-1237(2023)03-0161-07Epidemiological characteristics of COVID19 cases in a hotel Fangcang shelter hospital

1日,海南三亚发现 1名新冠肺炎确诊病例,随后新增病例不断出现,经流行病学调查和病毒基因测序分析发现,引起三亚“08 01”疫情的是新冠病毒奥密克戎变异株 BA.5.1.3,系我国首次检出,是目前已知的传播力最强的病毒,为外源性引入,感染者多与渔港、渔船、渔民和渔市相关。由于三亚新增感染者快速上升,三亚市的方舱医院大多处于在建状态,出现了“人等床”的情况,在当地医疗资源十分紧张的关键时刻,激活三亚市已有的酒店资源,将酒店改造成方舱医院是一个快捷有效的应对方案。海南医学院第一附属医院(简称海医一附院)医疗队和国家紧急医学救援队(海南)连续 3天改造出了 3座酒店方舱医院,并快速开舱收治患者,共约 2 100张床位,大大缓解了当地床位紧张的问题,显著减轻了疫情防控压力。本研究对 2022 年 8 月 10 日8 月 30 日期间海医一附院医疗队负责的某酒店方舱医院收治的新型冠状病毒感染者的流行病学资料进行统计分析,为优化疫情防控策略提供依据。1 资料与方法 1.1一般资料以 2022 年 8 月 10 日8 月 30 日期间海南省三亚市某酒店方舱医院收治的 703例新型冠状病毒感染者为研究对象。1.2方法收集该酒店方舱医院收治的新型冠状病毒感染者的流行病学资料,进行描述性流行病学分析,包括性别、年龄、分型、主要临床症状、基础病情况、新冠疫苗接种情况等。所有病
