The estimations of the COVID-19 incubation period: a systematic review of the literature	2020-05-23		.txt	text/plain	5969	280	50	One reason for this is that generally we can only discover the times when the patient was in contact with persons carrying the virus, and then assume that the incubation period runs from the earliest date of exposure to the appearance of clinical symptoms or medical diagnosis. et al [15] researched the early data regarding transmission dynamics for the virus in Wuhan, estimating the mean incubation period at 5.2 days (95% CI: 4.1-7.0), with the distribution's 95 th percentile being 12.5 days. They took individual patient histories from COVID-19 subjects in China (not from Hubei Province) for estimating the distribution of the time for generation, incubation, and the time span between onset of symptoms and isolation/diagnosis. The researchers undertook analysis of clinical data for 34 subjects submitting to elective surgery during the COVID-19 incubation period at four Chinese hospitals (Renmin, Tongji, Zhongnan, and Central) in Wuhan between January 1 and February 5, 2020.	./cache/cord-339506-pkusvf82.txt	./txt/cord-339506-pkusvf82.txt
