Cold snap to freeze out swine flu?

The temperature in Britain has dropped faster than Tiger Woods' trousers. It's been about 2C today and could drop even lower tomorrow. I'm willing to be corrected but this seems to be good news for the fight against swine flu - the virus preferring warmer weather. The old myth that cold weather gives you colds is true but only to a certain temperature. This cold snap is hopefully cold enough to even freeze out swine flu. Certainly everyone is wearing scarfs now which are probably as effective as face masks ever were!
