COVID-19的動態去世率

(2020-03-30 20:50:03) 下一個

去世率Case Fatality Rate (CFR)用來表示COVID-19的嚴重程度,它是這樣計算的:用累計去世人數D除以累計確診人數C,即CFR = D / C ,然後取百分比。可見,CFR其實準確表示的是COVID-19疫情的最終去世率。然而,在盛行階段,CFR會比最終的數據小很多,因為分母C的增加可能遠大於分子D的增加,對實時嚴重程度也就可能低估很多。另一個似乎更接近實時嚴重程度的比率是Closed Case Fatality Rate (CCFR),它用累計結案(Closed Case)的人數F做分母,即累計去世人數D加上累計康複人數R。因為所有確診最終隻有去世或康複兩種可能,CCFR比較大程度上也反映了疫情的可康複性,其計算公式是

CCFR=累計去世數/(累計去世數+累計康複數),或CCFR = D / F = D / (D + R) 取百分比.

實時CCFR(姑且稱為動態去世率)從更嚴重的方麵反映疫情的程度,最終也將等於CFR。上麵的定義及下表的數據世界各國(多於1000確診)取自https://www.worldometers.info/coronavirus/,美國取自https://ncov2019.live/data 這裏加入了CFR和CCFR,並對CFR從大到小排序(世界和美國總數在第一行)。

歐美許多國家隻查重症,所得到的確診人數乘以5是大致的總感染人數,因為感染後約80%為輕度患者。這樣得到的最終去世率似乎是以重症確診為基數,而不是所有感染者為基數的去世率,應該不低於20%。

4月26日

動態去世率:全世界的動態去世率CCFR從3月29日起就在21%左右(之前的數據沒注意),4月26日降為19.%;全美31.8%,各州暫變為未知. 

4月27日

全世界確診超過3米,美國超過1米,紐約過不了2天超過30萬。下麵的兩表為今日數據,將暫時不再更新。
