Zombie outbreak could wipe out humanity in 100 DAYS, experts reveal

A ZOMBIE outbreak could wipe out the human race in 100 days, according to a new university study.

 

The new research suggests that nearly everyone on Earth will be wiped out 100 days after a zombie invasion.
With the few survivors outnumbered a million to one by zombies, the human race would be driven to extinction by the undead.
Scientists predict just 100 days after a zombie outbreak, just 273 humans would be left on the planet.

Left scattered across the world, the future looks bleak with the study suggesting the survivors will be killed off within 12 months by the undead hordes.
The study – titled A Zombie Epidemic – was published in the Journal of Physics by the team from the Department of Physics and Astronomy at Leicester.
Researchers came to the alarming conclusion based on the assumption that a zombie would find at least one victim a day with a 90 per cent chance of infecting the doomed humans.

But all is not lost, with a second study claiming the world’s population would eventually be able to recover if humans decided to fight back and kill the zombies.
If survivors continue to have children coupled with zombies having a lifetime of just 20 days before they die from thirst and starvation in the post-apocalyptic world, then the human race could eventually beat the zombies.
The team also factored in how, over time, survivors may also be less likely to become infected after having experience of avoiding or fending off zombies.

They found that it would be possible for the world’s human population to survive the zombie epidemic under these conditions – and that eventually the zombie population would be wiped out and the human race would survive.
Using the SIR model – an epidemiological model that describes the spread of a disease throughout a population - the student team investigated the spread of a hypothetical zombie virus.
The model splits the population into three categories - those susceptible to the infection, those that are infected and those that have either died or recovered. The SIR model then considers the rates at which infections spread and die off as individuals in the population come into contact with each other.
 

As part of the formula, the students looked at S (the susceptible population), Z (the zombie population) and D (the dead population), suggesting that the average life-cycle of a zombie would be S to Z to D.
Course tutor, Dr Mervyn Roy, a lecturer in the University of Leicester’s Department of Physics and Astronomy, said: “Every year we ask students to write short papers for the Journal of Physics Special Topics. It lets the students show off their creative side and apply some of physics they know to the weird, the wonderful, or the everyday.”
It is not the first time Leicester has been forced to confront the possibilities of a zombie invasion.
In June 2011, Leicester City Council admitted it was unprepared for the walking dead, after reviewing a Freedom of Information request from a worried member of the public.
