Wear a Mask and Save Your Life: the 1918 Flu Pandemic

This post, by Megan Huang in the National Archives History Office, was originally published in 2018 marking the centenary of the 1918 influenza. It has been updated with additional images.

The 1918 influenza pandemic was a pandemic in the truest sense possible, affecting not just major population centers but also the most remote communities in the Pacific Islands and among Inuits in the far north.

About 500 million people may have been infected at some point, with 675,000 deaths in the United States alone. Globally, more people were killed by the influenza than by World War I, a concurrent, global conflict that lasted twice as long as the pandemic.

The war, however, contributed to the disease’s rapid spread. Crowded wartime conditions and troop movements across the Atlantic and throughout the war zones carried the flu worldwide.

The initial appearance of the disease in the United States was in the spring of 1918, but its effects were mostly benign and not much more severe than the seasonal norm.

It was not until autumn that the sickness made its most fatal strike—most of the estimated 20 to 100 million total deaths took place in a span of just several weeks in October and November.

Although medicine had made great strides since the end of the 19th century with the discovery of germ theory, doctors and scientists seemed to have been powerless against the flu, owing to the rapidly mutating nature of its virus. Responses instead focused on containing its spread. One of the most commonly promoted pieces of advice was to wear a mask.

The scale of the disease created mass panic. Churches and schools were closed, while local businesses and services that remained opened struggled with staff shortages. Too frightened to go out in public, people isolated themselves in their homes, leaving the streets nearly empty.

A medical student in normally bustling Philadelphia recalled, after driving 12 miles without passing a single other car, that “the life of the city had almost stopped.”

Yet the severe isolation was lamented by a strained medical community. The head of Philadelphia’s Emergency Aid turned bitter when desperate pleas for more volunteers went unanswered: “There are families in which the children are actually starving because there is no one to give them food. The death rate is so high and they still hold back.”

Among the people who stayed home were shipbuilders who were essential to the war effort. At L.H. Shattuck Co. in New Hampshire, only 54 percent of its workers showed up, and 41 percent at Connecticut’s Groton Iron Works.

Men on the front and would-be soldiers were also affected. One of the most alarming aspects of the 1918 flu was its penchant for targeting previously healthy young adults. Past flu outbreaks had killed more of the elderly and very young, but the 1918 strain targeted those who were in the prime of their life, who might have been on the battlefield if not for the illness.

The third wave began in early 1919 and ran through spring, which wasn’t as devastating as the fall but still caused significant illness and death. The outbreak finally ended in the summer of 1919. Scientists now know it was caused by an H1N1 virus, which continued as a seasonal virus for the next 38 years.
