Spanish Flu Pandemic (jan 1, 1918 – dec 31, 1920)

Description:

The 1918 flu pandemic (January 1918 – December 1920) was an unusually deadly influenza pandemic, the first of the two pandemics involving H1N1 influenza virus. It infected 500 million people around the world, including remote Pacific islands and the Arctic, and resulted in the deaths of 3-5% of the world's population, making it one of the deadliest natural disasters in human history. Most influenza outbreaks disproportionately kill juvenile, elderly, or already weakened patients. In contrast, the 1918 pandemic predominantly killed previously healthy young adults. There are several possible explanations for the high mortality rate of the 1918 influenza pandemic.

Estimated Deaths: 75,000,000
