How does Yersinia pestis affect your body?

Bubonic plague is the most common form of plague. This occurs when an infected flea bites a person or when materials contaminated with Y. pestis enter through a break in a person's skin. Patients develop swollen, tender lymph glands (called buboes) and fever, headache, chills, and weakness.

Is Yersinia pestis the same as the bubonic plague?

Bubonic plague is a type of infection caused by the Yersinia pestis (Y. pestis) bacterium which is spread mostly by fleas on rodents and other animals. Humans who are bitten by the fleas then can come down with plague. It's an example of a disease that can spread between animals and people (a zoonotic disease).
