Jukla jsem do odborné literatury (cizí, impaktovaný, ne pan doktor na idnesu říká), 3-5 jsem nenašla (zejména ty 3 nikde). Zato průměr kolem 5-7 dní zmiňují běžně, s tím že do 11 klidně. A ano, může to být i míň, třeba 2 dny, ale je to stejný extrém jako těch 11.
A novel coronavirus (2019-nCoV) is causing an outbreak of viral pneumonia that started in Wuhan, China. Using the travel history and symptom onset of 88 confirmed cases that were detected outside Wuhan in the early outbreak phase, we estimate the mean incubation period to be 6.4 days (95% credible interval: 5.6–7.7), ranging from 2.1 to 11.1 days (2.5th to 97.5th percentile). These values should help inform 2019-nCoV case definitions and appropriate quarantine durations.
------------
The median incubation period from infection with SARS-CoV-2 to onset of symptoms is approximately 5 days.
97.5% of people infected with SARS-CoV-2 will exhibit symptoms by 11.5 days.
Monitoring people exposed to SARS-CoV-2 for 14 days for development of symptoms should be sufficient to identify 99% of cases or more
-----------
The incubation period distribution may be modelled with a lognormal distribution with pooled mu and sigma parameters (95% CIs) of 1.63 (95% CI 1.51 to 1.75) and 0.50 (95% CI 0.46 to 0.55), respectively. The corresponding mean (95% CIs) was 5.8 (95% CI 5.0 to 6.7) days. It should be noted that uncertainty increases towards the tail of the distribution: the pooled parameter estimates (95% CIs) resulted in a median incubation period of 5.1 (95% CI 4.5 to 5.8) days, whereas the 95th percentile was 11.7 (95% CI 9.7 to 14.2) days.
