Influenza A (H1N1)

So I've been flying...a LOT. I went from the US to Korea (layover) to Malaysia and every country I went to, they made me fill out a Health Information Card due to the widespread fear of Influenza H1N1. HUGE HUGE FEAR! I was temperature checked as I passed through...they put some device near my chin. The US is one of the countries that they consider to be dangerous along with Canada, Mexico,
