Somethings similar are going around on this side of the pond. Everyone's getting them.
Speaking of covering up when sneezing etc, I was astounded when I was in Japan to see people walking around with "painter's masks"! I was joking to my Japanese friends that "here in Japan you guys have an over abundance of painters", but in all reality they were playing it smart. Imagine a city the size of Tokyo getting hit by a flue or virus and how quickly it'd spread?!
Good recuperations to everyone (me included) from the nasties!
