This year's flu outbreak is expected to be really bad. So when you catch it, there's a new free Facebook app that can help you figure out which one of your friends infected you.
The app is called "Help, I Have the Flu" and it analyzes your friends' profiles for signs that they're sick.
It looks for words in status updates like "sneezing" and "coughing." It also looks at people who've been making lots of late-night posts, because it figures people who are sleep deprived are at a higher risk of getting sick.
Then the app reports back to you on who most likely got you sick.
You can install the app at facebook.com/HelpRemedies.
