This is a bitch of a virus.

http://en.wikipedia.org/wiki/Norovirus

It gets into your system, incubates for 2 days. Then it reveals itself in a torrent of nonstop vomiting for a period of 24-60 hours.

Immediately following that, diarrhea until your system recovers.

Contagious, to the extent that it's the goddamn T-virus. The first time you puke, it goes airborne, then it survives on hard surfaces for 12 hours, cloth surfaces for 12 days, still water indefinitely.

Want to disinfect it? It resists alcohol (those little hand sanitizer bottles) and aerosols (febreeze, anyone?). Nothing other than good old fashioned chlorine kills it outright.

And it's inside me.
