中疾控新冠病例分析：八成患者为轻症 男性病死率高于女性

2月17日，中国疾病预防控制中心新型冠状病毒肺炎应急响应机制流行病学组在《中华流行病学杂志》上发表新冠肺炎最新研究《新型冠状病毒肺炎流行病学特征分析（the epidemiological characteristics of an outbreak of 2019 novel coronavirus diseases）》。

该研究根据传染病信息系统中报告的截至2月11日中国内地所有新冠肺炎共计72314例病例数据，对新冠肺炎流行病学特征进行了描述和分析。

It finds that 80.9% of infections are classified as mild, 13.8% as severe and 4.7% as critical. The number of deaths among those infected, known as the fatality rate, remains low but rises among those over 80 years old.
研究发现，80.9%的新冠病毒感染者为轻症，13.8%为重症，4.7%为危重。病死率保持在低位，不过在80岁以上人群中病死率有所上升。

Looking at the sex ratio, men are more likely to die (2.8%) than women (1.7%).
性别比例方面，男性患者的病死率为2.8%，高于女性（1.7%）。

The study also identifies which existing illnesses put patients at risk. It puts cardiovascular disease at number one, followed by diabetes, chronic respiratory disease and hypertension.
该研究还发现一些现有疾病会对感染者病情产生影响，影响最大的是心血管疾病，其次为糖尿病，慢性呼吸系统疾病以及高血压。

The paper says that a total of 3,019 health workers have been infected, 1,716 of which were confirmed cases. Five had died by February 11.
研究指出，共有3019名医护人员感染，其中1716名为确诊病例。截至2月11日，已有5名医护人员殉职。

据国家卫健委官方网站数据显示，2月18日0—24时，全国除湖北以外地区新增确诊病例56例，连续15日呈现下降态势。

The study suggests that the downward trend in the overall epidemic curve could mean that "isolation of whole cities, broadcast of critical information (e.g., promoting hand washing, mask wearing) with high frequency through multiple channels, and mobilization of a multi-sector rapid response teams is helping to curb the epidemic".
该研究指出，疫情总体曲线呈下降态势说明“城市封闭管理，多渠道高频率的关键信息传播（比如，宣传洗手、戴口罩等），以及多部门快速响应团队的发动在抑制疫情方面发挥了作用”。
