Our ragtag group of survivors aren’t doing well so far in The Walking Dead Season 4. A flu-type virus is wreaking havoc on the prison community, killing off people in droves. Talk about bad luck. Survive over a year into the zombie apocalypse only to die from a bad flu virus. Actually, this is an unfortunate but realistic outcome. In a world without vaccines, a complete absence of health care, poor hygiene and malnutrition, people would be dropping like flies from all types of previously treatable illnesses. Diseases like cholera would once again plague a post apocalyptic North America. At this point, judging purely from the condition and morale of the remaining humans, survival into a fifth season appears doubtful. Those that do survive will be existing merely on animal level. If you are looking for a spark of hope you will need to look elsewhere. The zombies aren’t the only walking dead in the best apocalyptic television series ever made.
