"Preparedness 101: Zombie Apocalypse" is a blog post made in May 2011 by the United States Centers for Disease Control and Prevention (CDC) that uses a zombie apocalypse to raise public awareness of emergency preparedness. In a blog post titled "Preparedness 101: Zombie Apocalypse", the director of the CDC's Office of Public Health Preparedness and Response, Rear Admiral Ali S. Khan writes: "Take a zombie apocalypse for example. That's right, I said z-o-m-b-i-e a-p-o-c-a-l-y-p-s-e. You may laugh now, but when it happens you'll be happy you read this, and hey, maybe you'll even learn a thing or two about how to prepare for a real emergency." Comparing the upcoming hurricane season and possible pandemics to "flesh-eating zombies" from the horror film Night of the Living Dead and the video game series Resident Evil, Khan recommends Americans prepare for natural disasters as they would have prepared for "ravenous monsters". The blog post was part of a larger zombie-themed campaign retired by mid-2022 and replaced with the Prep Your Health CDC website.
