摘要

摘要: 目的了解和探究四川省新型冠状病毒肺炎(coronavirus disease 2019, COVID-19)流行现状, 为现阶段防控策略与措施的制定提供参考依据。方法采用描述性流行病学方法深入剖析疫情变化, 明晰现状。结果四川省COVID-19病例主要集中于20~59岁人群, 男性占比略高于女性, 四个时期中有武汉/湖北暴露史病例者占比分别达到52.91%、21.97%、16.67%和0.00%。截至3月16日, 新增确诊病例与现有疑似病例均为0, 累计确诊病例达539例, 累计治愈病例为520例, 累计死亡病例3例。累计确诊病例在全省21个市州均有所分布, 成都居首位(144例, 26.72%)。除成都市武侯区外, 余下182个县(市、区)已无现症病例。结论当前四川省COVID-19疫情形势逐渐趋好, 但输入型感染风险仍然存在, 应持续加强防控力度, 深化分区分类防控, 精准科学施策。

Abstract: Objective To understand and explore the current status of coronavirus disease 2019(COVID-19)epidemic in Sichuan Province, and provide reference for the disease prevention and control at the present stage. Methods Descriptive epidemiological method was used to provide an in-depth analysis of the changes in the epidemic and clarify the status quo. Results The COVID-19 cases in Sichuan Pro-vince were mainly concentrated in the people aged 20-59, and the proportion of males was slightly higher than that of females. The proportion of cases with exposure history of Wuhan/Hubei among four periods were 52.91%, 21.97%, 16.67% and 0.00%, respectively. Up to March 16 th, both new confirmed cases and existing suspected cases were 0, with a total of 539 confirmed cases, 520 cured cases, and 3 fatal cases. All cumulative confirmed cases were distributed in 21 cities and prefectures in the province, with Chengdu ranking first(144 cases, 26.72%). Except for Wuhou district, one of districts in Chengdu, the other remaining 182 counties(cities, districts) have no symptomatic cases. Conclusions The current situation of COVID-19 epidemic makes gradual improvement in Sichuan Province. However, there is still the risk of imported infection. The stricter enforcement of existing strategies, such as region-specific and multi-level measures, and targeted and science-based policy, in the prevention and control of the epidemic is warranted.
