Just in case you're not worried about the flu, consider this: The Manhattan Soccer Club, a youth soccer organization, is banning handshakes and high-fives at games.

Children are awesome at carrying germs, thanks to school and other places where they are in close quarters and share equipment. CBS 2 obtained the letter the MSC sent to the parents of little Typhoid Madison's and Mark's:
