https://www.medrxiv.org/content/10.1101/2020.03.15.20036707v2.full.pdf+htmlwe inferred that
infectiousness started from 2.5 days before symptom onset and reached its peak at 0.6 days
before symptom onset (Figure 1b). The proportion of transmission before symptom onset
(area under the curve) was 44%. Infectiousness was estimated to decline relatively quickly
within 7 days of illness onset.
患者的具有传染性平均开始于症状出现2.5天之前,而症状出现之前0.6天时传染性最强。
44%的传播发生在症状出现前。
症状出现7天后传染性迅速下降。
看完只能说这病毒真牛逼~
理解了英国专家为什么说只需要隔离七天
部份解释了为什么最早期会有专家被骗认为不会人传人或有限人传人。
(这不是为专家洗地,而且我觉得他们作为专家在发言前理应更谨慎一些,不能以此理由来逃避责任。)
