How the Zombie Apocalypse Can Explain the Spread of Diseases

When the zombie apocalypse is upon us and the undead begin their global domination, we will all be left to fight for our lives or run for the hills. But did you know the scenario of a zombie apocalypse can help to explain just how diseases can spread in society?

In modeling a fictional zombie apocalypse, researchers are able to get a more in depth real world look at disease outbreaks worldwide. The techniques used to study a zombie apocalypse prove to be useful when researching real life diseases. Researchers at Cornell University have explained that a worldwide outbreak of a zombie apocalypse are similar to what a large scale outbreak of a virus like Ebola may look like. In the zombie apocalypse, there are four different stages to the virus.

First stage is the human stage, second is the infected, third is the zombie, and last is a dead zombie stage. These stages interact and combine with each other in a similar way to chemical reactions in the body.

In Depth Look into the Zombie Virus

If there was a zombie apocalypse, we usually assume that all areas are affected at the same time, and months after the initial outbreak occurs, there are pockets of survivors here and there. But realistically this isn’t the way that a disease outbreak will actually go down.

Don’t be too shocked that the zombie apocalypse we know of from our favorite movies and television shows isn’t entirely true. Researchers are able to provide you with a more inside look as to how an actual virus outbreak such as the zombie apocalypse would occur. They predict that dense populated cities will be the first to fall to the virus, and typically they’d likely fall quickly due to overcrowding and the spread of disease.

It would take time however for the zombies to penetrate through to more remote rural regions like that of the Rocky Mountains. The best place you would want to be during an outbreak is a place as far away as possible from people. This way you will be more unlikely to be near any places with an outbreak. Of course this model includes the assumption that people wouldn’t be on the move, so if in fact more people flocked to the mountains, well it wouldn’t be a safe option anymore.

Spread of Diseases

Take for example this image from Cornell University. This image shows a heat map, which depicts a 28 day stretch of the zombie outbreak. The lighter areas are those in which will be hit the hardest and fastest when a zombie outbreak does occur. Again this is all speculation from the research team at Cornell. More remote locations will have a huge advantage with less people, on the other hand supplies and resources will be limited.How Disease Spreads

How Disease Spreads

So do you remember that time a dog on your street came down with rabies, then later in the day, every other dog on the block ended up having rabies too? No? That’s because biting is a terrible way of spreading disease. So when looking at a zombie virus, to a traditional virus, biting may not spread the disease as fast as our movies have taught us.

Successful diseases have a clever way of spreading to their victims. The flu has killed over 10 million people because it hits through the air, the plague was spread by fleas, and sexually transmitted diseases work through sharing intimate contact with the infected. I don’t think anyone really will be in the mood to have sex with a zombie, so it looks like we’re safe there.

Traditional diseases have been able to mutate in order to infect more unsuspecting victims in a quick period of time. If biting is the method of infection with a zombie virus, we may just have time to run off to the middle of nowhere before the infection gets to us. And just like traditional diseases and viruses, the zombie virus shows a transition. If the overall total of the disease is below a certain level or point, well it’s more than likely that humans will come out on top, otherwise, look out.

If Hollywood has taught us anything, it’s that larger cities always fall first, even with a large amount of supplies. Perhaps the best route would be to plan ahead by gathering supplies and stocking up, while locating to a more remote location. And they always said living out in the middle of nowhere had its disadvantages. Seems to me that this is quite the opposite when we are dealing with an army of undead moving on us, wanting to devour our brains for breakfast, lunch and dinner.

Preparedness 101: Zombie Apocalypse From the CDC

A Brief History of Zombies
We’ve all seen at least one movie about flesh-eating zombies taking over (my personal favorite is Resident EvilExternal Web Site Icon.), but where do zombies come from and why do they love eating brains so much? The word zombie comes from Haitian and New Orleans voodoo origins. Although its meaning has changed slightly over the years, it refers to a human corpse mysteriously reanimated to serve the undead. Through ancient voodoo and folk-lore traditions, shows like the Walking Dead were born.

In movies, shows, and literature, zombies are often depicted as being created by an infectious virus, which is passed on via bites and contact with bodily fluids. Harvard psychiatrist Steven Schlozman wrote a (fictional) medical paper on the zombies presented in Night of the Living DeadExternal Web Site Icon. and refers to the condition as Ataxic Neurodegenerative Satiety Deficiency Syndrome caused by an infectious agent. The Zombie Survival GuideExternal Web Site Icon. identifies the cause of zombies as a virus called solanum. Other zombie origins shown in films include radiation from a destroyed NASAExternal Web Site Icon. VenusExternal Web Site Icon. probe (as in Night of the Living DeadExternal Web Site Icon.), as well as mutations of existing conditions such as prionsExternal Web Site Icon.mad-cow diseaseExternal Web Site Icon.,measlesExternal Web Site Icon. and rabiesExternal Web Site Icon..

The rise of zombies in pop culture has given credence to the idea that a zombie apocalypse could happen. In such a scenario zombies would take over entire countries, roaming city streets eating anything living that got in their way. The proliferation of this idea has led many people to wonder “How do I prepare for a zombie apocalypse?”

Well, we’re here to answer that question for you, and hopefully share a few tips about preparing for real emergencies too!

Disaster or Blackout Emergency SuppliesSome of the supplies for your emergency kit

Better Safe than Sorry

So what do you need to do before zombies…or hurricanes or pandemics for example, actually happen? First of all, you should have an emergency kit in your house. This includes things like water, food, and other supplies to get you through the first couple of days before you can locate a zombie-free refugee camp (or in the event of a natural disaster, it will buy you some time until you are able to make your way to an evacuation shelter or utility lines are restored). Below are a few items you should include in your kit, for a full list visit the CDC Emergency page.

  • Water (1 gallon per person per day)
  • Food (stock up on non-perishable items that you eat regularly)
  • Medications (this includes prescription and non-prescription meds)
  • Tools and Supplies (utility knife, duct tape, battery powered radio, etc.)
  • Sanitation and Hygiene (household bleach, soap, towels, etc.)
  • Clothing and Bedding (a change of clothes for each family member and blankets)
  • Important documents (copies of your driver’s license, passport, and birth certificate to name a few)
  • First Aid supplies (although you’re a goner if a zombie bites you, you can use these supplies to treat basic cuts and lacerations that you might get during a tornado orhurricane)

Once you’ve made your emergency kit, you should sit down with your family and come up with an emergency plan. This includes where you would go and who you would call if zombies started appearing outside your door step. You can also implement this plan if there is a flood, earthquake, or other emergency.

  1. Identify the types of emergencies that are possible in your area. Besides a zombie apocalypse, this may include floods, tornadoes, or earthquakes. If you are unsure contact your local Red Cross chapter for more information.
  2. Pick a meeting place for your family to regroup in case zombies invade your home…or your town evacuates because of a hurricane. Pick one place right outside your home for sudden emergencies and one place outside of your neighborhood in case you are unable to return home right away.
  3. Identify your emergency contacts. Make a list of local contacts like the police, fire department, and your local zombie response team. Also identify an out-of-state contact that you can call during an emergency to let the rest of your family know you are ok.
  4. Plan your evacuation route. When zombies are hungry they won’t stop until they get food (i.e., brains), which means you need to get out of town fast! Plan where you would go and multiple routes you would take ahead of time so that the flesh eaters don’t have a chance! This is also helpful when natural disasters strike and you have to take shelter fast.

Never Fear – CDC is Ready

If zombies did start roaming the streets, CDC would conduct an investigation much like any other disease outbreak. CDC would provide technical assistance to cities, states, or international partners dealing with a zombie infestation. This assistance might include consultation, lab testing and analysis, patient management and care, tracking of contacts, and infection control (includingisolation and quarantine). It’s likely that an investigation of this scenario would seek to accomplish several goals: determine the cause of the illness, the source of the infection/virus/toxin, learn how it is transmitted and how readily it is spread, how to break the cycle of transmission and thus prevent further cases, and how patients can best be treated. Not only would scientists be working to identify the cause and cure of the zombie outbreak, but CDC and other federal agencies would send medical teams and first responders to help those in affected areas (I will be volunteering the young nameless disease detectives for the field work).
