Does everyone die in Dawn of the Dead?

No not everyone dies in dawn of the dead! well not really, at the end you see Kenneth,Ana,one of the mall security(not CJ), and the young girl that they save from the truck get off a boat on an island and Chips(the dog) runs off, which attracts Zombies and you see the guy with the cam put it down and then a zombie bites him and falls over, so i guess everyone dies.
