If there is one disease that anyone has been scared of by such tragedy when studying about it in history class, it is, without a doubt, the Black Death.

This is because this plague, which ravaged Europe in the 14th century, killed between 75 and 200 million people.

There were more than 50 million victims in just 10 years (1343-1353).

For this reason, it could not be left out of our list of the biggest pandemics in the world.

caused by bacteria Yersinia pestis, the Black Death spread through contact with infected fleas and rodents, as did typhus.

Among its symptoms, fever, chills, headache, fatigue, muscle aches, vomiting and, mainly, enormous swelling of the lymph nodes, in addition to black spots around the skin.

One of the main factors for its high spread was the lack of hygiene and basic sanitation, making it difficult to contain the Black Death.

In addition to Europe, the disease has reached all of China, the Middle East and Russia.
