Module 5

The current pandemic is affecting the whole world. Not only affecting health, killing and making many people sick but also affecting the economy and other aspects of our world. Doing some research on previous virus’ outbreaks, quickly we find the most famous and notorious pandemics. These outbreaks cost the lives of millions of people all across the world. The most notorious ones are the Black Death and also the Spanish Flu. 

The Spanish flu, was an unusually deadly influenza pandemic. Lasting from January 1918 to December 1920, infecting 500 million people, about a quarter of the world's population at the time. The death toll is estimated to have been anywhere from 17 million to 50 million, and possibly as high as 100 million, making it one of the deadliest pandemics in human history. 

Most influenza outbreaks disproportionately kill the very young and the very old, with a higher survival rate for those in between, but the Spanish flu pandemic resulted in a higher than expected mortality rate for young adults. Scientists offer several possible explanations for the high mortality rate of the 1918 influenza pandemic. The Spanish flu was the first of two pandemics caused by the H1N1 influenza virus; the second was the swine flu in 2009

The Black Death, 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, from 1347 to 1351. The plague created religious, social, and economic upheavals, with profound effects on the course of European history.

The Black Death probably originated in Central Asia or East Asia, and is estimated to have killed 30% to 60% of Europe's population. It took 200 years for Europe's population to recover to its previous level. Outbreaks of the plague recurred at various locations around the world until the early 20th century.
