On this day in history in 1918 the Deadliest flu pandemic in recorded history began. Hundreds of soldiers at Fort Riley, Kansas, are sick with a virulent form of influenza, prompting the first reporting of the epidemic. The flu will go on to infect some 500 million people and kill between 50 million and 100 million, according to most estimates. Lasting from 1918 to 1920.
