Plage of Justinian (541-542)
It was a early bubonic plague outbreak that spread through the Oriental Roman Empire territory during Justinian's government.
Yersinia pestis, the bacteria responsible, lived in the flees that remained on rats. A clear example of zoonotic disease. By the end of 542, this Plague had claimed between 25-50 human lifes. That is one quarter of population then. -

The Quarantine
The Black Death had started in Asia, and it expanded in Europe later. The fault of this belongs to the rats that lived in Venetian sailors´ ships; and to this people too. Italy tried to stop the disease expanding by applying a port blockade to the sailors that lasted 40 days. -
Period: 1347 to 1351
Black Death (the major outbreak)
This was when the Plague of Justinian, as the bubonic illness, returned and took revenge, being stronger than before. Infected people had symptoms such as dark swellings (bulbes) in armpits and groin. In total, by the last days of 1351, one third of worldwide population (Europe and Asia) had passed away: 150 million people approximately. -
Period: 1492 to
XVI century: the conquest and colonisation era
Smallpox, chickenpox and measles had struck European people, but had not extinct human beings in the Old World. When European explorers and conquerors arrived to the Americas, they had prepared a powerful biological weapon: the illnesses they already had endurance to. Indigenous people had nothing to do, in terms of immunity defense, when explorers started the war for the Conquest.
20 million Native American lives were lost: 90 per cent of pre-colombian population. -
Spanish Flu (1918-1920)
Seventy five million people were caught by its deadly presence..., that means 4% of global population then died.
The Spanish Flu appeared during WWI. Perhaps, the toughest hit the Flu gave is that she attacked especially young adults– 99% of her victims were under the age of 65 years old–.
