This year marks the centennial of the start of World War I. To honor it, Popular Science is combing through our archives to bring you the best of our original war coverage–from the emergence of tanks, airplanes, and other military tech, to essays examining the relationship between war and eugenics.
Just as the First World War was winding down, another disaster struck: The so-called “Spanish flu,” an influenza virus with unique mutations that made it unusually virulent and deadly. Anywhere between 20 percent and 40 percent of the world’s population contracted it. An estimated 50 million people died, including about one person out of every 160 in the U.S. War conditions hastened the disease’s spread, as troops moved around the world and the war effort left few healthcare workers to administer to civilians.
The pandemic left a lasting mark on societies and science, so we thought contemporary issues of Popular Science might have some interesting reporting on the phenomenon.
