A20: Plague

A20.3: Plague meningitis

You have been infected with the plague. The plague is caused by bacteria called Yersinia. The bacteria usually pass from fleas to rodents such as rats. Humans can become infected if they come into contact with these infected animals. If a person is bitten by an infected flea, they can also catch the plague. Humans can also infect one another via the air or the skin.

Your meninges are inflamed due to the bacteria. The meninges lie around the brain and spinal cord. Inflamed meninges may be accompanied by bad headaches or neck pain. You may have a high temperature or vomiting.
