There are case reports of it being far longer than 14 days:

> A 70-year-old man in China’s Hubei Province was infected with coronavirus but did not show symptoms until 27 days later, the local government said on Saturday, meaning the virus’ incubation period could be much longer than the presumed 14 days.
- runamok 7y agoI mean is there a chance they were infected later? E.g. they thought source A caused it but in reality Source B ten days later did?
- Seenso 7y agoMaybe, but I just looked the locations in the article, and it looks like his home is in a town in a rural area [1]. Given it's a smaller area, maybe that constrained things enough that they were able to infer that he must have gotten it during his visit to Wuhan. I can imagine several scenarios with an elderly man that might have allowed them to pinpoint his infection to that visit [2]. However, there's just not enough detail in the article to reconstruct how the local Chinese government ruled out everything but his visit as the source of his infection. [1] Shennongjia, Hubei. Looks like it's a "county" with about 75k people: https://en.wikipedia.org/wiki/Shennongjia https://en.wikipedia.org/wiki/Shennongjia [2] For instance: he visited Wuhan, self-quarantined immediately after returning which limited his contact with others, then 27 days later developed infection. Every contact he did have was tracked and confirmed negative. That's total speculation, though.
