Every year the flu hits and while it may just seem like a miserable couple of weeks for those who get it, it actually kills 500,000 people worldwide a year.
Google is releasing a new tool called Google Flu Trends which tracks search queries to show where the flu is flaring up.
Of course, the best way to avoid the flu is to get a flu shot. Google provides a Flu Shot locator on the right hand sidebar of Flu Trends. (Of course, you can call your doctor or check with your local pharmacy, too.)
