The Creeping Feather From 19 73

The plot of the creeping flesh from 19 73, which had peter cushing and christopher lee in it. The basic idea here is a curse idea, a contagious curse. Man catches curse from cursed individual and then has to deal with the curse. It's not unlike many werewolf stories, except instead of turning into a wolf, a in killing people. And that ultimately makes it more terrifying because it's these things that we can point to in the real world that he's suffering in.
