Not to freak you out, but the bubonic plague was actually spread by insects. Which tiny creatures pass this disease from animals to people?

Believe it or not, the plague - or Black Death - was and continues to be spread by tiny fleas, more specifically the rat flea. An infected rat gets bitten by a flea and then that flea can pass it to people through its bite.
