There are strong parallels between the COVID-19 pandemic and the 1918 flu pandemic, considered to be the deadliest of the 20th century.

The 1918 flu pandemic killed an estimated 50 million worldwide, including nearly 675,000 Americans, according to the Centers for Disease Control and Prevention.

To date, more than 95.6 million people have been infected with COVID-19 worldwide. More than 2 million have died, including at least 400,000 Americans, according to real-time data compiled by Johns Hopkins University.

Here’s a look at some of the parallels between the two pandemics.

In 1918, the first flu cases were reported in March at an Army base in Kansas. Without testing capabilities, the flu spread widely and easily. The movement of military during World War I aided the spread.

Social distancing and mask wearing

During the flu pandemic, the only hope was social mitigation efforts. The development of flu vaccines didn’t happen until the 1940s. Health officials understood that mask wearing, social distancing and frequent hand-washing helped slow the spread. Cities that embraced efforts such as mask mandates and social distancing, along with the closures of businesses, schools, theaters and houses of worship, saw lower numbers of deaths. A similar pattern has occurred now.

Back then, many masks were made of gauze and cheesecloth and held in place with elastic or tape.

With COVID, people were initially encouraged to make homemade cloth masks because of a shortage of medical masks for hospital workers.

Though medical professionals urged mask wearing in 1918, many people resisted, just as they do now for similar reasons. Mask mandates came and went across the country during the flu pandemic. Officials worked to characterize mask use as a patriotic effort.

San Francisco was the first U.S. city to mandate the wearing of face masks in October 1918. People were fined and imprisoned for failing to comply. The mandate was only in place for four weeks initially, with the spread of the flu curtailed briefly. The ordinance was re-instituted again in January 1919 as cases spiked.

The Anti-Mask League, formed in San Francisco in January 1919, protested the wearing of masks, viewing it as an unconstitutional limit of individual liberty. The refusal to wear masks and socially distance didn’t become as politicized or as organized as it has now, however. The League’s efforts seemed to have been a rare exception. Most people complied with the ordinances.

Reopening too early

The 1918 pandemic occurred in three waves: the first in the spring, the second, far deadlier wave, in the fall, and then the final wave in the winter/spring of 1919.

Cities, such as New York, were hard hit by the coronavirus in the spring of 2020. Then case numbers subsided through the summer and mitigation efforts were eased in many places. Then a resurgence of cases emerged in the fall and winter in both urban and rural settings and worldwide.

As is the case now, various measures to contain the deadly flu were taken inconsistently across the country. In 1918, there was a first wave and then a flattening of the curve. Many places such as California lifted restrictions too early, leading to a second wave of infections. The same situation has occurred with the COVID-19 pandemic. California was initially successful in the battle against COVID-19, but now faces a dire situation this winter.

In late September 1918, Philadelphia’s decision not to cancel its Liberty Loan parade, held to pay for the war effort, took a toll. In October, more than 10,000 people died from the flu in the city. At one point, the city had more than 500 bodies waiting for burial. Cold-storage plants needed to be used as temporary morgues and packing crates were utilized as coffins, according to the CDC.

In parts of the country, hospitals were so overwhelmed with patients that makeshift hospitals were created in schools and other buildings. The 1918 flu took an estimated 195,000 American lives in October 1918 — the deadliest month of the pandemic.

In 2020, many parts of the U.S. never shut down to prevent the spread of the coronavirus. South Dakota welcomed hundreds of thousands of people for a 10-day biker rally in Sturgis. According to The Associated Press, at least 290 people in 12 states who attended the rally tested positive for COVID-19. The Washington Post reported that South and North Dakota, along with Wyoming, Montana and Minnesota, led the country in new infections per capita weeks after the rally. With attendees from all across the country, however, and the lack of contact tracing, documenting the full extent of the spread from the event was difficult.


While many places closed schools in 1918, three cities — New York, Chicago and New Haven, Connecticut — did not. In New York, classroom windows were kept open and children studied on rooftops and other outdoor spaces even through the cold winter months. Schools in the city were deemed to provide better health conditions than crowded and unsanitary tenements.

In late 2020, New York City was the only major U.S. city to reopen public schools for in-person learning. A mask mandate and social distancing measures were put in place. COVID-19 testing protocols were also implemented. Schools have opened and closed in the city based on city-wide infection rates and cases within individual schools. A patchwork response across the country included fully remote learning and a return to school with no mitigation measures such as mask mandates.

End of year holidays

Both pandemics saw spikes in case numbers due to family gatherings and holiday celebrations. In a Dec. 12, 1918, Boston Globe article, Dr. M. Victor Safford of Boston’s Health Department was quoted as stating, “Most of the influenza cases reported in Boston today are traceable to visits to homes of persons who have been or are ill with influenza.”

Despite an explosion in COVID-19 cases across the U.S. and warnings from the CDC, more than three million travelers passed through TSA screening checkpoints in the run-up to Thanksgiving. The American Automobile Association (AAA) predicted almost 48 million Americans would travel by road for the holiday and another 84.5 million would travel between Dec. 23 and Jan. 3. In the four-day period right before Christmas, more than four million people traveled by air. That was the largest period of air travel since the pandemic began last March.

The holiday surge the past two months put coronavirus hospitalizations at their highest levels since early last spring.

On Jan. 19, 2021, it was reported by Philadelphia ABC station WPVI that 18 family members tested positive after a holiday party in Pennsylvania.


In 1918, “there was no leadership or guidance of any kind directly from the White House,” historian John M. Barry, author of “The Great Influenza: The Story of the Deadliest Pandemic in History,” told TIME magazine. President Woodrow Wilson was so focused on the war effort. “Hundreds of thousands of Americans died without President Wilson saying anything or mobilizing nonmilitary components of the U.S. government to help the civilian population,” according to the book “Shall We Wake the President: Two Centuries of Disaster Management from the Oval Office” by Tevi Troy. Wilson suffered from the flu in April 1919 in the middle of peace negotiations to end World War I.

The federal government response to the COVID-19 pandemic has been widely criticized. Former President Donald Trump repeatedly downplayed the severity of the crisis. States have been largely left to manage the crisis on their own. Many in the White House, including the president and vice president, as well as Republican members of Congress, have openly refused to wear masks. Trump contracted COVID-19 in October 2020. One coronavirus outbreak infected 34 White House staffers.

The 1918 flu took a heavy toll. Entire families were wiped out and those who survived were widowed or orphaned. There was a significant economic impact as well. The pandemic finally ebbed after a third wave by the summer of 1919. It is believed the flu strain became so widespread that a level of herd immunity developed. That herd immunity came at a considerable cost in lives.

Medicine and science have come along way since then, but few lessons were learned from 1918. Vaccines for COVID-19 were developed fairly rapidly, but not before a huge loss of life, economic devastation and the suspension of normal life. New virus variants, considered more infectious, have shown up, complicating the ability to contain the pandemic. The challenge now is managing a surging crisis while ramping up production of vaccines and an effective vaccination program.
