I somewhat recall reading a prophesy from a saint, or it was one of the warnings from Our Lady (but I can't remember which apparition - La Salette, Akita, Lourdes, Fatima, etc.), stating that one of the bad things that will fall on humanity during the apocalypse or chastisement is blackened, dead bodies will be everywhere. The instruction was for the living not to touch the bodies or go near them, lest they fall victim to the same death. This gave me the impression it was some sort of plague (but the prophesy/message might have specified it was a plague - I can't remember...). Also, this might be apropos to the 3 Days of Darkness warning or something of that nature.

Does anyone know the prophesy/warning and where it originated?
