“The Walking Dead” has recently become one of the most popular television series out there. It is the story of Rick Grimes, a sheriff’s deputy, who wakes up from a coma to find a post-apocalyptic world over run with zombies or “walkers,” as they are referred to in the show. This show much like the movie “Zombieland,” revolves around a group of survivors trying to stay alive and find others who aren’t infected. In both the movie and the show, the zombies seem to be created through a virus like infection that is extremely widespread and devastating. According to a Discovery Channel program, the actuality of something like this actually happening is very unlikely. Associate Professor of Microbiology and Immunization at the Bloomberg School of Public Health, John’s Hopkins University, Andrew Pekosz describes the type of virus that would be able to cause a “zombie apocalypse.” The virus would be one that infects a person, but does not display symptoms for weeks, but is still able to be transmitted from person to person. In a scenario like this, by the time anyone actually knew they were sick from virus; there would be hundreds if not thousands infected. A virus that acted in this manner would make it extremely difficult to enact any public health measures. It would be hard to act preventatively because many people would be infected long before they knew there was even a virus spreading and it would be impossible to head off the virus with vaccines because so many would be infected before they even knew the virus existed. According to Pekosz though this kind of scenario may be more than a virus can handle. Typically a virus causes an illness as soon as it enters the host, so to ask it to remain dormant, symptomless, while still spreading is almost impossible. He says that there could be a possible link between causing a disease and spreading the virus, much like with the flu. It may have to be passed through coughing or sneezing, which are symptoms that would alert the person of an illness. When asked if it was possible for such a virus to infect the whole population, he responds with a no. It would be very hard for one single virus to infect an entire population. Some people would simply not be exposed to the virus. If they live in a separated area with little to no contact with other people, they may not ever come in contact with the virus. Still others will build an immunity from a small does and just not react to it, but will be immune to a later infection. Others will have a natural immunity, like Matt Damon’s character in “Contagion.” Will all of this together, a good percent of this population would be not be affected by the population and most likely a virus that would cause a zombie apocalypse isn’t even likely. So for now, even though zombie shows and movies seem to be catching society’s interest, there isn’t really a way for something like the “Walking Dead” to occur.
