A young man and woman can hear a couple in the next room having sex (sexual moans and noises are heard.) They have a giggle about it. We then see the couple in the next room, a brief sex scene in which a man thrusts slowly on top of a woman, there is no visible nudity besides their shoulders and his back, as the scene takes place beneath a sleeping bag

A young man makes a young woman strip naked to check if she is 'infected', we see her pulling down her pants etc. but we don't see any nudity.

'Fuck' is said many times, also 'shit, hell, damn, ass, dick, piss, bitch.

A man who is about to have his arm cut off is injected with something to help take the edge off the pain.

There are several disturbing scenes featuring the parasites and the victim's different reactions to them. The gory parts are very realistic and can be unsettling.
