Has swine flu made you change your ways?

There are fears that a swine flu outbreak that has leapfrogged from Mexico, across North America and into Europe could become a global pandemic,  rekindling memories of the SARS crisis that caused widespread turmoil six years ago.

The flu virus spreads quickly between humans and although it has so far only killed people in Mexico, governments across the world are taking measures to try to reduce its impact.

As the number of cases increases, what have you done to protect yourself? Have you stocked up on hand sanitizer, called in sick, or opted to walk to work instead of taking public transportation? Have you had to cancel travel plans or are you going about your life business as usual?
