What was black disease?

Published in Disease History 2 mins read

The "black disease" is another name for the bubonic plague, a severe illness that historically caused widespread death.

Understanding Bubonic Plague

The bubonic plague, commonly known as the Black Death, is an infection caused by bacteria that are primarily spread to humans through infected fleas. These fleas typically live on rodents, such as mice and rats, which act as carriers.

How it Spreads:

  • Infected Fleas: The primary mode of transmission is through the bite of a flea carrying the plague bacteria.
  • Rodents: Rodents, particularly rats, are the main reservoirs for the bacteria.
  • Human Contact: While not the primary route, humans can also transmit the plague through direct contact with infected tissues or fluids.

The Black Death:

The bubonic plague, specifically, was called the Black Death during the Middle Ages because of the dark patches it caused on the skin due to internal bleeding. It ravaged Europe, resulting in the death of millions of people.
