Infected world

It's late, your in your caravan alone watching the T.V. The news is showing the weather for the next few days but then, half way through the weather segment, it cuts to the main she hosts. They are taking about a infection that is transmitted by the saliva or blood of a person who has the virus, entering the body of an infected person. The infection makes you rabid, it makes you a bit slower but a lot stronger. People who have the infection are reported to look like their body is just a rotting, protective shell for whatever the virus is.
