Chicago would be overrun by a zombie apocalypse in just 60 days, according to a new study.
Researchers at Argonne National Laboratory used a high-powered computer model, normally used to simulate the spread of diseases such a Ebola and MRSA, to figure out how long it would take for a zombie-like virus to take over the Windy City.
The team ran the model hundreds of times, varying the parameters of the disease, including training programs to kill zombies and communications from city officials that tell people how to avoid them.
In the base scenario, two million people were "zombified" by day 60.
Another study also reveals that Chicago is among the cities with the lowest chances of surviving a zombie apocalypse.
Researchers at Emsi, CareerBuilder's labor market analysis firm, conducted a study gauging survival rates against a zombie attack based on concentration of occupational skills and industries in different cities across the nation.
The study used a standard, flesh-eating virus transmitted through bitting or contact with infected blood as the constant disease among 53 different cities.
Cities were scored on eight different factors within four categories: ability to defend against the virus, ability to contain the virus, ability to find a cure and ability to outlast the epidemic with an ample food supply.
Boston had the best odds for survival, followed by Kansas City and Salt Lake City.
Meanwhile, New York City had the greatest risk of becoming infected, along with Tampa, Florida and Los Angeles. Chicago ranked number 45 out of the 53 cities tested.
