【知識點】
病死率（case fatality rate，CFR）指一段時間內患有某個病症的所有患者中，因該病死亡人數所佔的比例。病死率的計算方式就是，用該病患者死亡人數除以該病所有患者人數。
與之相關的還有一個概念就是，發病率（incidence rate），指特定人群在一定時間內發生某個病症新病例的頻率。
The CFR in Hubei province was 3.1 percent, as the majority of the deaths occurred in the province, which saw a death toll of 414, over 97 percent of the total.死亡患者主要集中在湖北省，累計414人，佔全國97%，湖北省確診病例的病死率為3.1%。
In Wuhan, the capital city of Hubei, the CFR stood at 4.9 percent and the death toll was 313, accounting for 74 percent of the national total.武漢市的死亡人數是313人，佔全國死亡的74%，武漢確診病例病死率是4.9%。

The fatality rate outside Hubei was only 0.16 percent.如果除掉湖北省，其他省份的病死率是0.16%。
More than 80 percent of the deaths were elderly people over 60 years old, and over 75 percent had at least one underlying disease such as cardiovascular diseases, diabetes and tumors.死亡患者以高齡為主，80%以上都是60歲以上的老年人，75%以上有一種以上的基礎疾病，如心血管病、糖尿病以及腫瘤等。
