Commonly affected species include ground squirrels, prairie dogs, rabbits and wood rats. While rats and cats were blamed for the plague and killed in the Middle Ages, the disease mainly spread person to person via fleas and lice.
Q. What animals helped spread the Black Plague?
In cases of plague since the late 1800s—including an outbreak in Madagascar in 2017—rats and other rodents helped spread the disease. If Y. pestis infects rats, the bacterium can pass to fleas that drink the rodents’ blood. When a plague-stricken rat dies, its parasites abandon the corpse and may go on to bite humans.

Q. How did the Black Death start?
The plague arrived in Europe in October 1347, when 12 ships from the Black Sea docked at the Sicilian port of Messina. People gathered on the docks were met with a horrifying surprise: Most sailors aboard the ships were dead, and those still alive were gravely ill and covered in black boils that oozed blood and pus.
Q. What are the stages of the bubonic plague?
Bubonic plague symptoms and signs include painful and enlarged or swollen lymph nodes (an enlarged lymph node due to plague is called a bubo), chills, headache, fever, fatigue, and weakness. Septicemic plague (Black Death or black plague) symptoms and signs include fever, weakness, abdominal pain, chills, and shock.
Q. Why was bubonic plague so deadly?
“The plague bacterium Yersinia pestis needs calcium in order to grow at body temperature. “We found that this is because Y. pestis is missing an important enzyme.” Bubonic plague has killed over 200 million people during the course of history and is thus the most devastating acute infectious disease known to man.
Q. Are Buboes painful?
Buboes are a symptom of bubonic plague, and occur as painful swellings in the thighs, neck, groin or armpits. They are caused by Yersinia pestis bacteria spreading from flea bites through the bloodstream to the lymph nodes, where the bacteria replicate, causing the nodes to swell.
Q. What was the last pandemic in the USA?
The 1918 influenza pandemic was the most severe pandemic in recent history. It was caused by an H1N1 virus with genes of avian origin. Although there is not universal consensus regarding where the virus originated, it spread worldwide during 1918-1919.
Q. How long did the 1918 flu last?
The influenza pandemic of 1918–19, also called the Spanish flu, lasted between one and two years. The pandemic occurred in three waves, though not simultaneously around the globe.
Q. What was the cure for the 1918 influenza epidemic?
With no cure for the flu, many doctors prescribed medication that they felt would alleviate symptoms… including aspirin, which had been trademarked by Bayer in 1899—a patent that expired in 1917, meaning new companies were able to produce the drug during the Spanish Flu epidemic.
