A20.7: Septicaemic plague

You have the plague. The illness has caused you to have blood poisoning.

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.

The bacteria have caused you to have blood poisoning. Blood poisoning is the most severe outcome of a disorder that has been caused by pathogens. Blood poisoning is also known as sepsis. With this, pathogens or their toxins may spread throughout the body via the blood. If the body’s immune system does not react properly to this, organs and tissue can become damaged. The damage may be extremely severe. It may be impossible to get it under control. Blood poisoning makes you very ill. You may become confused and sleepy. You may have a fever and a very fast pulse. Your breathing may also be abnormally fast. Blood poisoning can affect many organs in the body. For example, the kidneys may no longer produce enough urine.
