A20.2: Pneumonic plague

You have the plague.

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 lungs are inflamed due to the bacteria. Lung inflammation can be accompanied by coughing. This is sometimes accompanied by purulent or bloody sputum. The patient sometimes finds breathing more difficult than usual, or has chest pain.

If you have the plague you can feel run down. You may have a high temperature or headaches and vomiting. Your awareness can also be disrupted.
