  4. Black Death • Plague is a severe and potentially deadly bacterial infection. • Causes, incidence, and risk factors • Plague is caused by the bacteria Yersinia pestis. Rodents, such as rats, carry the disease. It is spread by their fleas. • People can get the plague when they are bitten by a flea that carries the plague bacteria from an infected rodent.

  5. Black Death • A plague lung infection called pneumonic plague can spread from human to human. When someone with pneumonic plague coughs, tiny droplets carrying the bacteria move through the air. Anyone who breathes in these particles may catch the disease. An epidemic may be started this way.

  6. Black Death • In the Middle Ages in Europe, massive plague epidemics killed millions of people. Plague can still be found in Africa, Asia, and South America. • Today, plague is rare in the United States, but it has been known to occur in parts of California, Arizona, Colorado, and New Mexico.

  7. Black Death • Bubonic plague symptoms appear suddenly, usually after 2 - 5 days of exposure to the bacteria. Symptoms include: • Chills • Fever • General ill feeling (malaise) • Headache • Muscle pain • Seizures • Smooth, painful lymph gland swelling called a bubo • Commonly found in the groin, but may occur in the armpits or neck, most often at the site of the infection (bite or scratch)
