1. Bubonic Plague
The bacillus Yersinia pestis is the source of the deadly infectious disease known as the bubonic plague. It has existed for centuries and is sometimes referred to as “The Black Death” and “The Pestilence.” The first recorded case of it was the Plague of Justinian, which occurred between 541 and 549 AD.
Infected fleas or small mammals like rodents can spread the Y. pestis bacteria, which can then infect people when they are bitten or scratched.
Despite being widespread, since the bacteria was identified in 1894, scientists have quickly devised methods of treating it and stopping its spread, and it is now generally treatable with things like antibiotics!
The Black Death (1346–1553) inspired the creation of public health measures like quarantines, the isolation of sick people, and the use of protective clothes for doctors.
