What made the Black Death the plague so deadly?

Bacteria that cause the bubonic plague may be more virulent than their close relatives because of a single genetic mutation, according to research published in the May issue of the journal Microbiology. “The plague bacterium Yersinia pestis needs calcium in order to grow at body temperature.

How did the black plague end?

The most popular theory of how the plague ended is through the implementation of quarantines. The uninfected would typically remain in their homes and only leave when it was necessary, while those who could afford to do so would leave the more densely populated areas and live in greater isolation.

In cases of plague since the late 1800s—including an outbreak in Madagascar in 2017—rats and other rodents helped spread the disease.

How lethal was Black Death?

Plague can be a very severe disease in people, with a case-fatality ratio of 30% to 60% for the bubonic type, and is always fatal for the pneumonic kind when left untreated. Antibiotic treatment is effective against plague bacteria, so early diagnosis and early treatment can save lives.

Who found the cure for the Black Plague?

Credit for discovering the bacterial cause of plague is accorded to the French physician Alexandre Yersin (1863–1943), for his bacteriological investigations in June 1894 in Hong Kong during a deadly epidemic [32].

How was the Black Death cured?

Some of the cures they tried included: Rubbing onions, herbs or a chopped up snake (if available) on the boils or cutting up a pigeon and rubbing it over an infected body. Drinking vinegar, eating crushed minerals, arsenic, mercury or even ten-year-old treacle!

Therefore, rather than bubonic plague, which is transmitted to humans through bites from infected rat fleas (and then can be transmitted between humans, according to some research), they concluded that this must have been a pneumonic plague that made its way into the lungs of the infected and spread through coughs and …
