發病13天內都還可能養得出病毒
CT35以上也有部分可以養得出病毒
herlee 的5天論實在是自相矛盾

Relationship between ‘symptom to test’ interval and virus isolation
There were 246 samples from 176 symptomatic cases where the date of symptom onset was known, of which 103 (42%) samples from 81 cases were culture-positive. Detection of cultivable virus peaked around the time of symptom onset (Figure 3). Median duration of virus shedding as measured by culture was 4 days (IQR: 1–8; range: −13 to 12, with symptom onset dates based on symptom recall). The culture positivity rate was significantly higher during week 1 than week 2 (74% vs 20%; p=0.002). Ten days after symptom onset, the probability of culturing virus declined to 6.0% (95% CI: 0.9–31.2%) (Table 1). Where cases were followed up within outbreak investigations, 13 individuals who were asymptomatic at the time of sampling developed symptoms within 14 days of sampling and were classified as presymptomatic, of whom seven were culture-positive. Regression analysis indicates that presymptomatic samples were at least as likely to be culture-positive as samples taken during symptomatic phases.
拿特例當成通例?? 實驗數據是這樣判讀的嗎 ??
總共81例陽性當中,只有一例是13天造成 CPE 現象 ,這根本達不到統計學上顯著性差異
您確定這是由採樣的 SARS CoV2病毒所造成的 CPE???
可信的virus shedding 病毒藉由分泌及/或排出而散播的時間是 4天 ←白紙黑字
這個 13天造成CPE的培養皿有再次培養 ? 確定仍然能再侵入下一個細胞嗎?
而且, 這中間 有13例採樣時無症狀 , 在14天內發展為有症狀 , 這裏面有7例培養出病毒
那一天開始算起 ?
