What starts in Day 5-9 is typical. But it could start in day 2. It could start in day 10. It does not always take the same number of days to reach the day 12 column.“But, onset of symptoms varies from one to the next” Everyone keeps mentioning onset. I know it’s 2 -21 days for the incubation period. That’s not what I’m talking about.....disease progression. Vomiting is around day 10...so that gives you a rough idea of onset. See chart “progression of illness if left untreated”.

That’s an assumption, specific to Mr. Duncan.
