2-14 days represents the current official estimated range for the novel coronavirus COVID-19. However, a case with an incubation period of 27 days has been reported by Hubei Province local government on Feb. 22  In addition, a case with an incubation period of 19 days was observed in a JAMA study of 5 cases published on Feb. 21.  An outlier of a 24 days incubation period had been for the first time observed in a Feb. 9 study. WHO said at the time that this could actually reflect a second exposure rather than a long incubation period, and that it wasn't going to change its recommendations. Period can vary greatly among patients. Mean incubation period observed: 3.0 days (0 - 24 days range, study based on 1,324 cases) 5.2 days (4.1 - 7.0 days range, based on 425 cases). Mean incubation period observed in travelers from Wuhan: 6.4 days (range from 2.1 to 11.1 days).
Viruses behave differently between people of different age and sex and general health of them. This is a new mutation that theyre still learning about.Its complicated that some people show little to no sign of infection or symptoms and recover but carry the virus. The only thing that is obvious is its highly contagious and easily spread.
Incubation period of 5.2 days on average A Chinese study published in the New England Journal of Medicine on Jan. 30, has found the incubation period to be 5.2 days on average, but it varies greatly among patients. The Chinese team conducting the study said their findings support a 14-day medical observation period for people exposed to the pathogen.
Below is an extract of the study findings (highlight added by Worldometer):
Among the first 425 patients with confirmed NCIP, the median age was 59 years and 56% were male. The majority of cases (55%) with onset before January 1, 2020, were linked to the Huanan Seafood Wholesale Market, as compared with 8.6% of the subsequent cases.
The mean incubation period was 5.2 days (95% confidence interval [CI], 4.1 to 7.0), with the 95th percentile of the distribution at 12.5 days.
In its early stages, the epidemic doubled in size every 7.4 days. With a mean serial interval of 7.5 days (95% CI, 5.3 to 19), the basic reproductive number was estimated to be 2.2 (95% CI, 1.4 to 3.9).
Conclusions On the basis of this information, there is evidence that human-to-human transmission has occurred among close contacts since the middle of December 2019. Considerable efforts to reduce transmission will be required to control outbreaks if similar dynamics apply elsewhere. Measures to prevent or reduce transmission should be implemented in populations at risk.

Just heard that Italy is on “Lockdown/Shutdown” Etc Because Of a Spurge Of Coronovirus 19 outbreaks !! But dunno if that’s 💯 % right as to what that exactly means as in what areas etc etc as don’t think it’s Whole Of Italy etc ... But it just goes to show that even though the Government is trying to say And shoving forwards that “It’s Getting Better Etc” And Not So Much News Coverage Etc Something Is “Clearly Not Right” !!! But like I say “I could be wrong and misunderstanding “ which is not that hard for me to do hahahaha:)
Well that didn't last long. The BBC online news feed seems to have lost the 'Italian job', it's not showing now on their headlines. From what I saw earlier the Italian government have stopped a number of footy matches but let some major ones go ahead.
Everyone I've spoken to apart from my lad is just showing apathy. My lad has stocked up, his O/H is a nurse so she'd wise him up. Sister is a well-heeled snobby commie doesn't believe there's a problem as aunty hasn't broadcast it.
Am I being over concerned? I don't think so, this bug has all but shut down the worlds biggest producer who's shut shops, factories and instituted near enough martial-law.
Italy sounds like a fck-up, too little too late and likewise quarantined whole towns and when it spreads from there it'll be another China and nothing has been said by our government apart from how to sneeze safely and wash your hands............
I'm doing a top-up shop today for food and fuel and kids food all being well. When it comes here I don't want to be among potential infected fighting for scraps and if we don't get to that situation it will always be used anyway.
The length of the incubation period and flu like symptoms along with the over crowded close contact nature of life nowadays means we will most likely at some point come into contact with the virus.We will survive or not. When cultures persist with deficient intelligence and awareness inevitably they will trip up.The consumption and culturally required torture to death of live animals to improve the meat they claim,does not sound like a society with much intelligence.Global epidemic is inevitable as is our fragile organic mortality.Expect the worst and protect yourself in any way you can.x
