Want to know which of your dastardly, good-for-nothing friends gave you the flu? There's an app for that. Tool of North America and design-minded OTC healthcare company Help Remedies present "Help, I have the flu," a new Facebook app that analyzes your friends via keywords, posts, and check-ins to find who has the flu -- either so you avoid them completely or so you can track them down and
kill them tell them how disappointed you are that they didn't quarantine themselves. The app also lets you send a message to your guilty friends that advises them that they won't be enjoying your company for a little bit.
