Re: Green card holders and the immediate family of US citizens get a pass.
I find that if you're firm with viruses and speak to them in a firm, slow, clear and (most importantly) loud voice - in english of course (or as close as an American can get to that...) - then they do as they're told.
We can't let johnny-foreigner get all uppity, be he virus or no.
I also suggest we send a gunboat. Someone fetch Raquel Welch, a submarine and a miniaturising ray at once!
