Plague is a bacterial disease that is infamous for causing millions of deaths in the Middle Ages in Europe. Many historical references describe the illness, which has been referred to as the Black Death. The first reported plague pandemic began in 541 A.D. and lasted for over 200 years, killing an estimated 100 million people or more throughout the Mediterranean basin. The so-called Black Death, or pandemic of the Middle Ages, began in China and made its way to Europe, causing the death of 60% of the entire population. The third, or modern, pandemic started in China in the 19th century and spread to port cities all over the world. Most recently, the World Health Organization reported an outbreak of plague in Madagascar in Nov. 2014. The outbreak affected over 100 patients and caused at least 40 deaths.
Rodents and many other kinds of animals can be infected with plague-causing bacteria. People contract the bacteria through bites of fleas that have fed on infected rodents. Humans can also develop the infection from handling fluids or tissues from infected animals. People with plague pneumonia can also transmit the infection to other humans via coughing infectious droplets into the air.
Bubonic plague affects the lymph nodes (another part of the lymph system). Within 3 to 7 days of exposure to plague bacteria, you will develop flu-like symptoms such as fever, headache, chills, weakness, and swollen, tender lymph glands (called buboes -- hence the name bubonic).
