A new Facebook app uses social networking to try and prevent users from catching the flu.
According to Time, "Help I Have The Flu," scans through your friends posts looking for key words indicating flu activity.
The app looks for friends' comments and statuses relating to flu activity, like "coughing" and "sneezing" and even tracks trends such as late night posts, since lack of sleep is considered a risk factor for getting sick.
Even though the app is for entertainment, it allows users to send sick friends a discount for medicine.
