Model of human teeth

Even among those who brush and floss every day, the human mouth isn’t exactly clean. It contains about 700 different kinds of microbes, including bacteria and fungi, some of which are helpful — but not so helpful that you’d ever want to be bitten by another person. Human bites are in fact even more dangerous than other animal bites, as they’re more likely to become infected as a result of that bacteria. Maybe all those zombie movies are onto something.

A dog’s mouth is cleaner than a human’s.

Oops, incorrect!

It's a fib

This oft-repeated statement is little more than a popular misconception, most likely stemming from the fact that dogs lick their own wounds.

Health care providers treat roughly 250,000 human bites each year, around 10% of which result in an infection among children, who are more likely to be bitten than adults (usually by another child). Humans account for only 3% of all bites seen in emergency rooms, however. Dog bites are by far the most common, followed by those of cats, while bites from smaller animals such as mice, rabbits, and hamsters are more rare.

If any creature has put its teeth on you and broken the skin, you’re advised to seek medical treatment regardless of how cute the offending animal was — better safe than sorry.

Zombie folklore originated in Haiti.

Though we tend to think of them as cinematic creations, zombies predate motion pictures and can be traced back to Haitian folklore, which is itself rooted in African religious practices. According to the mythos, dead people can be brought back to life by voodoo sorcerers known as bokors.

The zombie (originally spelled “zombi”) was first written about in America in an 1838 article called “The Unknown Painter” published by the Alton Telegraph. In it, a person enslaved by the Spanish artist Bartolome Esteban Murillo claimed that a “zombi” made nightly appearances in Murillo’s studio to work on his apprentices’ paintings, a fantastical notion that was dismissed.
