There's so many things wrong with what you just said. It's not just the "sniffles". Even if someone young and healthy gets it, they will survive but there's a chance they'll spread to someone who's at a much higher risk.
This is the stage to NOT give up and just let it spread all over. Being overly cautious is still much better than what could happen if this spills over to an uncontrollable level (which I fear is already the case in some areas).
