We’ve mostly figured it out now, but it means the incubation period would’ve been about 7 days for my wife (who caught it first). Long story short, it was literally impossible for any of us to have picked it up in the 3-4 day incubation period that’s claimed as the average now. None of us had left the house or interacted with anyone lol
I don’t know what the research shows on incubation periods now, or how long it can theoretically take. I know the original strain had a longer incubation period like that.
