[討論] 無症狀比例

事實根據基礎來源:
https://science.sciencemag.org/content/early/2020/03/13/science.abb3221
作者用了一個數學模型
資料來源是375個中國城市
得到的結論是在限制旅遊前:
在1/23限制旅遊前,有82~90%的感染者沒被追蹤到,這些大多是輕症
大約有79%的被追蹤到的確診者,是被無症狀者感染(感謝antonis)
這段比較難搞懂:
Per person, the transmission rate of undocumented infections was 55%
of documented infections ([46%–62%]), yet, due to their greater numbers,
undocumented infections were the infection source for 79%
of documented cases.
模型從感染到確診大約是9天(用線性資料估算則是6.6天)
如果真的要在沒有疫苗/或特效藥前終止疫情
看來手段要很嚴厲?
