I don't think that is actually the case, I hope you had quite a few you first-hand accounts of people who had it and it was not 'barely a cold'. more like 4 days in bed, still very lethargic for the next 2 or 3 days. it depends on the viral load that is received. small load = milder symptoms. I think this is why it is so dangerous for healthcare workers, they get prolonged exposure and them by the time they become ill they have a lot of virus. if you picked it up off someone on public transport, for example, then your exposure would have been maybe 10 or 15 minutes, so you get a milder case.
