That's a good idea, and I dont think we've seen any die off. Like they did in 28 Day Later. They would eventually just run out of people, and die off.
We haven't seen any die off but Micheal and Peggs saw one almost completely withered away and still moving. Maybe some of the just regular zombies and not mutations are dying off. Like their bodies are just rotting away until their is nothing left to rot.
