Schools aren't closing any more-there's no point. But we're sending home our sore throats and headaches fairly smartly. None of the usual "Have a drink of water, dear, and tell me how you feel after playtime."
We did that for a couple of weeks until everyone came to terms with the fact that it was also allergy season and you just can't keep an entire office home for an extended period of time out of sheer paranoia. "Pretending that you already know the answer when you don't is not actually very helpful." ~Migeru.
I think at least one parent at my son's school has had it, though.
(Normally you need a note either right away or after 3 days of illness, depending on your employment contract.) You have a normal feeling for a moment, then it passes. --More--
