Add Patient Zero to Facebook and create a virus that you can use to infect all your Facebook friends. Once you add this Facebook application you can create a virus. Make the virus stronger by answering questions, then send it to your friends and infect them with it.

If you get infected by another person's virus you can cure yourself or you can get vaccinated before you catch the virus by answering some other questions. Use the Patient Zero map to find out how far your virus has spread.

Creating your virus is fun. First you get to choose an image for your virus. I chose something spotty that looks like it could spread easily. Then you can name your virus. I chose something gory. Decide how you want your virus to be spread. I chose food borne because I think that's pretty scary. Then you can create a description for your virus. Mine is easily spread and very contagious with a red bumpy rash and high fever.

Answer 10 questions. The more you get right the stronger your virus will be. Now you can choose who you want to infect. Choose wisely and spread your virus to the Facebook world.
