The show depicts a lawless setting where resources are scarce. There is rarely bloody violence, and one instance of sexual assault that is upsetting but not graphic; the overall tone is dark and the characters are constantly under threat. Victims of the infection go into a frenzy, which can be intense and disturbing.
Throughout the show, victims of the viral infection go into convulsions, vomit, or foam at the mouth before dying. These scenes are usually brief.
