The Spanish Flu

The Spanish flu of 1918-1919 infected one-third of the world’s population and killed between 50 and 100 million people. Its rapid spread and high mortality rate made it one of the deadliest pandemics in modern history.

Covid-19

First identified in December 2019, Covid-19 rapidly became a global pandemic. As of five years later, the estimated death toll ranges from 19 to 36 million people, making it one of the deadliest pandemics in recent history.
