David Cronenberg's 1970s sexual transmission horror centres on the residents of a suburban high-rise apartment building who are being infected by a strain of parasites that turn them into mindless, sex-crazed fiends out to infect others by the slightest sexual contact.

Citizens of a small town are infected by a biological weapon that causes its victims to become violently insane, in this classic from George A Romero (Night of the Living Dead).
