I don’t know the background story about this video, but the visuals are pretty creepy. A man laid naked on a hospital bed has maggots crawling all over the old wounds on his head and inside his eye sockets. The eyelids are closed so it’s hard to tell if the eyeballs are still OK, but the presence of maggots doesn’t suggest anything good.
He gets his hair shaved off, although it looks like it would fall off on its own. The doc also cleans his wounds but at 2:50, when he pulls off a flap of scalp, the underlying maggot infestation shows just how badly this man is infected. The language spoken in the video sounds Chinese, or some other Asian variety.
