Transcript of Zombies
Based on the following components:
What Does the Virus Entail?
The Way out
We all know those creepy, flesh chomping, half rotted lurkers America has come to love... but could they actually exist? By reflex, most would say no.
It may not be that far-fetched.
Bacterial Mutation/ Manifestation
The Zombie Virus and Outbreak is plausible.
The first stage of the virus takes out the majority of the population.
It is spread by air, and direct contact with pathogens.
In this first wave, the people are terminated by a very high fever.
...the dead RISE
Or any flesh
are craved by these "zombies," causing them to attack living humans.
The Typical Zombie
Moans and Groans
After the initial infection, survivors that are bit will catch the virus.
Very Rapid Spread
Population Majority Dies
Mortality Rate 100%
Only by obliterating the brain, can a zombie be "killed."
This is the point of origin for the virus.
(Pt. A) Bacterial Spray
(Pt. B) Mass Transmission
(Pt. C) Similar Viruses
(Pt. D) Mutation Possibilities
Pt. A: Bacterial Spray
Poster paper or cardboard
Petroleum jelly (Vaseline)
Purpose & Procedure
Place petroleum gel on paper until coated. Place paper/cardboard on the wall (dry side down). On
floor, mark off with tape the distance, increments of 2.5 ft. Take glitter and blow at paper from each
mark. Record results at each mark with photos. When will the glitter no longer reach the paper?
This will prove whether or not an airborne pathogen is a viable way to spread initial disease to many
Just to Give an Idea
Some glitter stuck to my hands
When the glitter was blown, it went in all directions, but majority went semi straight ahead.
Up until about 7.5 feet, most glitter was reaching the cardboard
Covering up some of the blow caused the glitter to not travel as far
There is evidence that a sneeze can travel up to 3 ft
40% Rhinoviruses last on surfaces for an excess of 7 days (less effective at 24hrs) on hands 1 hr,
*Flu Viruses (i.e. Parainfluenza virus) lasts on hard surfaces for 24 hrs, tissues/clothe/paper 15 min, Hands 5 min, 2-3 hrs airborne droplets,
Stomach Viruses (i.e. E Coli., Salmonella, Clostridium Difficile, Camplyobacter, Norovirus, Rotavirus.) 1-4hrs on hard surfaces, Noro for Days/ weeks on hard surfaces
The zoonotic bacterium Yersinia pestis, that causes plague, can live in humidified soil for in excess of 40 weeks. It can live in the infected flea for the fleas life
Yersinia pestis lasts in the air for an hour (CDC)
The glitter got on the paper most between 2.5 and 5 feet. At 7.5 feet, half the glitter just ended previously. At 10 feet, most glitter did not reach the cardboard. At 12.5 Feet no glitter reached the board.
Though the glitter did not travel far, it did have a wide range and stayed on my hands. Considering that bacteria have the ability to last for large spans of time outside the body, this makes airborne spread a viable way to spread the zombie virus.
Pt. B: Mass Transmission
A Semi-closed room
30 minutes- an hour
Purpose & Procedure
Put glitter on hands before entering the closed room. Touch normal surfaces like, door knobs, desks, keyboards, seats, etc. This should leave glitter on these surfaces. Take note of the number of people in the room, and how long the class/ club will go on for. Allow a normal club or class period to ensue, without alerting people of the experiment. People may intentionally skew results, making the experiment for naught. At the end of the class/ club, ask all personnel in the room if they have glitter on them. Record this number. Did the majority have the glitter? What does this say for the way infection can spread?
This is to determine if the virus could spread in such numbers so rapidly.
Observations & Data
There are currently 13 students and staff in this room.
The club lasts 30 minutes
The glitter is going everywhere.
People seem to be unaware of the glitter.
At the end of the club 11 out of the 13 people had the glitter.
That is 85% infection, 2 to 3 people got infected per minute
Infection by Mass Transmission is extremely effective,due to the time period it takes to catch a virus, the amount of people catching said virus, and the amount of time bacteria can be out of the host for.
The Bubonic Plague
The bubonic plague (pneumonic, septicemic) could be spread from infected flea bites, from rodents. It can also be contracted through the air, in droplets from the lungs of an infected human or animal (pneumonic). The bacteria (Yersinia Pestis) is found worldwide and can survive in many conditions. The incubation period is very brief- 2 to 6 days for bubonic, 1-3 days for pneumonic. This causes rapid deterioration, with a very high fever, chills, headache, weakness, and swollen infected lymph nodes (buboes). This will cause the disease to very rapidly spread throughout the body, and infect other parts. Without very rapid treatment, with antibiotics, the infected die in a matter of days. In days of old, this created a 90% mortality rate- it was extremely rare to survive. In history, the plague holds a remarkable place. It is believed the collapse of the Roman Empire was initiated when soldiers came back from the Persian War of AD 165. It made 3 other appearances in times, as well. The Justinian plague dates back to 541 AD and lasted for another 200 years, killing over 100 million people. Then there was the black death, that originated in China 1334. This traveled along trade routes to Constantinople and then to Europe, killing ⅓ of the entire population. The final run, began in the 1860’s and spread to port cities, lasting 20 years.
Rabies is a preventable viral disease affecting mammals. It infects the central nervous system, leading to the brain and eventually causing death. Symptoms include, high fever, headache, and generalized weakness and discomfort. Later, symptoms develop into insomnia, anxiety, confusion, slight or partial paralysis, excitation, hallucinations, agitation, hypersalivation (increase in saliva), difficulty swallowing, and hydrophobia (fear of water). Death usually occurs within days of the onset of these symptoms. Rabies is an acute encephalomyelitis that almost always progresses to coma or death within 10 days after the first symptom. It is spread through the saliva of the infected, often brought into the bloodstream through a bite
Necrotizing fasciitis. It is caused by group A Streptococcus (group A strep), Klebsiella, Clostridium, E. coli, Staphylococcus aureus, and Aeromonas hydrophila, among others. Group A strep is considered the most common cause of necrotizing fasciitis. It is a bacterial infection that spreads rapidly and destroys the body's soft tissue.
The body can not rid of HIV because “When HIV infects a cell, the virus can hide within the cytoplasm (the jelly-like fluid that fills the cell) or integrate into the cell’s genetic material (chromosomes). Shielded from the immune system, HIV can lie dormant in an infected cell for months or even years. These cells serve as a latent reservoir of the virus. Antiretroviral drugs are capable of suppressing HIV, even to undetectable levels in the blood, but they cannot eliminate the virus hiding in these latent reservoirs. A key NIAID research priority is to learn how HIV establishes these latent reservoirs and to develop strategies to purge the virus from the body”
The hypothesis is correct, proving the zombie virus is
The basic format of a virus is genetic information (such as RNA & DNA) wrapped in proteins and lipids.
These viruses are incapable of survival outside a host for long, and make their way into eukaryotic cells.
From here, the virus utilizes the cells energy to replicate itself with RNA and DNA copies. A mutation occurs when this copying process gets messed up, and an enzyme is improperly replicated.
