People are so ready to get back to life, forgetting that in 1918 the second wave of the Spanish Flu reportedly killed 20-50 million. The first wave only killed 3-5 million. History does indeed repeat.

The horrific scale of the 1918 influenza pandemic—known as the “Spanish flu”—is hard to fathom. The virus infected 500 million people worldwide and killed an estimated 20 million to 50 million victims—that’s more than all of the soldiers and civilians died during World War I consolidated. 

While the global pandemic lasted for twenty-four months, a significant amount of deaths were packed into three exceptionally rough months in the autumn of 1918. Annalists now accept that the deadly sharpness of the Spanish Flu’s “second wave” was caused by a mutated virus dispersed by wartime company actions.

When the Spanish Flu first appeared in early March 1918, it had all the hallmarks of the seasonal Flu, albeit a profoundly transmissible, infectious contagious, dangerous, and destructive strain. One of the first recorded cases was Albert Gitchell, a U.S. Army cook at Camp Funston in Kansas, who was hospitalized with a 104-degree fever. The virus expanded swiftly through the Army base, home to 54,000 troops. By the end of the month, 1,100 soldiers had been hospitalized, and 38 had fallen after contracting pneumonia.

As U.S. troops stationed en masse for the war effort in Europe, they carried the Spanish Flu with them. Throughout April and May of 1918, the virus flowed like wildfire through England, France, Spain, and Italy. A predicted three-quarter of the French military was tainted in the spring of 1918 and as many as half of British troops. Yet the first wave of the virus didn’t appear to be particularly deadly, with symptoms like high fever and malaise usually lasting only three days. According to restricted public health data from the time, fatality rates were related to annual Flu.

Historians believe that the fast spread of Spanish Flu in the fall of 1918 was somewhat to impute on public health officials opposed to imposing quarantines during wartime. In Britain, for example, a government official named Arthur Newsholme understood full well that a strict private lockdown was the most reliable way to fight the scope of the profoundly infectious virus. But he wouldn’t jeopardize damaging the battle manufacturers by keeping munitions industry artisans and other noncombatants homely.

According to many researchers, “the constant needs of warfare proved to incur [the] risk of spreading disease” and encouraged Britons to “carry on” during the pandemic.

A severe nursing shortage further thwarted the public health answer to the crisis in the United States as thousands of nurses had been deployed to military camps and the front lines. The deficit was worsened by the American Red Cross’s refusal to use trained African American nurses until the worst of the pandemic had already passed.

1918 Flu Pandemic Commemoration

The 1918 influenza pandemic was the most severe pandemic in recent history. It was caused by an H1N1 virus with genes of avian origin. Although there is no universal consensus regarding where the virus originated, it spread worldwide from 1918-1919.  In the United States, it was first identified in military personnel in spring 1918. It is estimated that about 500 million people or one-third of the world’s population became infected with this virus. The number of deaths was estimated to be at least 50 million worldwide with about 675,000 occurring in the United States.

Mortality was high in people younger than 5 years old, 20-40 years old, and 65 years and older. The high mortality in healthy people, including those in the 20-40 year age group, was a unique feature of this pandemic. While the 1918 H1N1 virus has been synthesized and evaluated, the properties that made it so devastating are not well understood. With no vaccine to protect against influenza infection and no antibiotics to treat secondary bacterial infections that can be associated with influenza infections, control efforts worldwide were limited to non-pharmaceutical interventions such as isolation, quarantine, good personal hygiene, use of disinfectants, and limitations of public gatherings, which were applied unevenly.
