This figure was appropriated from a PBS website detailing the great flu pandemic of 1918.
675,000 Americans died

• The 1918 influenza virus killed more than 20 million people worldwide.

• Although the disease that caused the worldwide epidemic was called the “Spanish flu,” the virus apparently is a mutation that evolved in American pigs and was spread around the globe by U.S. troops mobilized for World War I.

• In the two years that the epidemic ravaged the earth, one-fifth of the world’s population was infected. The flu was most deadly for people ages 20 to 40.

• An estimated 675,000 Americans died of influenza during the pandemic, 10 times as many as in the world war.

• Of the U.S. soldiers who died in Europe, one-half of them fell to the influenza virus and not the enemy.
