Can anyone give me a list of movies with quarantines?

I'm trying to write a zombie book and I need to take a look at quarantine procedures of the government in movies. But I mean really horror/sci-fi movie quarantine, not like H1N1 quarantine. I mean like biohazard, Resident Evil, containment-or-nuke quarantine. For movies, I've already gotten The Crazies, Resident Evil, Quarantine, and 28 Days/Weeks Later. Can anyone suggest any others like those?
