A guide to surviving a zombie apocalypse has been published in America.

The nation's Centre for Disease Control and Prevention has helpfully provided hints in a blog on how to cope if the undead start walking the earth.

It states: "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."

Tips include keeping an "emergency kit" including medications, duct tape, a battery-powered radio, clothes, copies of important documents and first-aid supplies.
