Answer 1

Answer:

1. The Black Death-Invention of Quarantine

Black Death scientific ally know as Bubonic Plague was the most fatal pandemic recorded in human history, resulting in the deaths of up to 75–200 million people in Eurasia and North Africa, peaking in Europe from 1347 to 1351.

2.Three of the deadliest pandemics in recorded history were caused by a single bacterium, Yersinia pestis, a fatal infection otherwise known as the plague.

The Plague of Justinian arrived in Constantinople, the capital of the Byzantine Empire, in 541 CE. It was carried over the Mediterranean Sea from Egypt, a recently conquered land paying tribute to Emperor Justinian in grain. Plague-ridden fleas hitched a ride on the black rats that snacked on the grain.

The plague decimated Constantinople and spread like wildfire across Europe, Asia, North Africa and Arabia killing an estimated 30 to 50 million people, perhaps half of the world’s population.

“People had no real understanding of how to fight it other than trying to avoid sick people,” says Thomas Mockaitis, a history professor at DePaul University. “As to how the plague ended, the best guess is that the majority of people in a pandemic somehow survive, and those who survive have immunity.”

3.Smallpox-Smallpox is a highly contagious and deadly disease caused by the variola virus. It was estimated to have infected 300 million people in the 20th Century before it became the only human infectious disease ever to be completely eradicated

4.Marburg Virus-The genus Marburgvirus is the taxonomic home of Marburg marburgvirus, whose members are the two known marburgviruses, Marburg virus and Ravn virus.The Marburg virus is transmitted to people from fruit bats and spreads among humans through human-to-human transmission. The Marburg virus causes severe viral haemorrhagic fever in humans. The average MVD case fatality rate is around 50%.

5.The Spanish Flu

The Spanish flu was an influenza pandemic that spread around the world between 1918 and 1919, according to the CDC. It was caused by an H1N1 virus, with an avian (bird) origin, though it's unclear exactly where the virus originated. The CDC estimates that about 500 million people (or one-third of the world’s population) became infected with the virus. It ultimately caused least 50 million deaths worldwide with about 675,000 deaths happening in the U.S.
