Nope...
Not zombies. Comparing any modern zombie to the ancient Haitian voodoo just doesn't make sense. Zombie has been completely redefined ever since Romero brought us Night of the Living Dead. Redefined as reanimated corpses whose sole motive is to hunt you down and eat you. Any modern zombie movie ever made has had this as the basis of the antagonists. There might be a couple obscure flicks out there that deviate from this path a bit, but otherwise it holds true.
To argue that these are zombies simply because the old voodoo shaman weren't corpses either is weak and lazy, and totally in line with most internet goons of today who like to argue for the sheer sake of it. They are people. They are very much alive. They have contracted a serious virus not unlike what we encounter today with things like HIV, Polio or Smallpox. These infected do not hunt you to eat you. They want to beat you to death as is shown throughout the film. They do bite sometimes early on, but its not because they want to devour your flesh, its a means to inflict pain, kill and spread. They would not starve to death if they were what we acknowledge today as zombies.
Call them what the movie intended, and does call them throughout... The infected.
