The Spanish flu pandemic of 1918-1919 was the deadliest pandemic in world history, infecting some 500 million people across the globe—roughly one-third of the population—and causing up to 50 million deaths, including some 675,000 deaths in the United States alone. The disease, caused by a new variant of the influenza virus, was spread in part by tr...
Influenza, or flu, is a virus that attacks the respiratory system. The flu virus is highly contagious: When an infected person coughs, sneezes or talks, respiratory droplets are generated and transmitted into the air, and can then can be inhaled by anyone nearby.
Additionally, a person who touches something with the virus on it and then touches his or her mouth, eyes or nose can become infected.
Did you know? During the flu pandemic of 1918, the New York City health commissioner tried to slow the transmission of the flu by ordering businesses to open and close on staggered shifts to avoid overcrowding on the subways.
Flu outbreaks happen every year and vary in severity, depending in part on what type of virus is spreading. (Flu viruses can rapidly mutate.)
In the United States, “flu season” generally runs from late fall into spring. In a typical year, more than 200,000 Americans are hospitalized for flu-related complications, and over the past three decades, there have been some 3,000 to 49,000 flu-related U.S. deaths annually, according to the Centers for Disease Control and Prevention.
Young children, people over age 65, pregnant women and people with certain medical conditions, such as asthma, diabetes or heart disease, face a higher risk of flu-related complications, including pneumonia, ear and sinus infections and bronchitis.
The first wave of the 1918 pandemic occurred in the spring and was generally mild. The sick, who experienced such typical flu symptoms as chills, fever and fatigue, usually recovered after several days, and the number of reported deaths was low.
However, a second, highly contagious wave of influenza appeared with a vengeance in the fall of that same year. Victims died within hours or days of developing symptoms, their skin turning blue and their lungs filling with fluid that caused them to suffocate. In just one year, 1918, the average life expectancy in America plummeted by a dozen years.
It’s unknown exactly where the particular strain of influenza that caused the pandemic came from; however, the 1918 flu was first observed in Europe, America and areas of Asia before spreading to almost every other part of the planet within a matter of months.
Despite the fact that the 1918 flu wasn’t isolated to one place, it became known around the world as the Spanish flu, as Spain was hit hard by the disease and was not subject to the wartime news blackouts that affected other European countries. (Even Spain's king, Alfonso XIII, reportedly contracted the flu.)
One unusual aspect of the 1918 flu was that it struck down many previously healthy, young people—a group normally resistant to this type of infectious illness—including a number of World War I servicemen.
In fact, more U.S. soldiers died from the 1918 flu than were killed in battle during the war. Forty percent of the U.S. Navy was hit with the flu, while 36 percent of the Army became ill, and troops moving around the world in crowded ships and trains helped to spread the killer virus.
Although the death toll attributed to the Spanish flu is often estimated at 20 million to 50 million victims worldwide, other estimates run as high as 100 million victims—around 3 percent of the world’s population. The exact numbers are impossible to know due to a lack of medical record-keeping in many places.
What is known, however, is that few locations were immune to the 1918 flu—in America, victims ranged from residents of major cities to those of remote Alaskan communities. Even President Woodrow Wilson reportedly contracted the flu in early 1919 while negotiating the Treaty of Versailles, which ended World War I.
The Spanish Flu did not originate in Spain, though news coverage of it did. During World War I, Spain was a neutral country with free media that covered the outbreak from the start, first reporting on it in Madrid in late May of 1918. Meanwhile, Allied countries and the Central Powers had wartime censors who covered up news of the flu to keep moral...

Scientists still do not know for sure where the Spanish Flu originated, though theories point to France, China, Britain, or the United States, where the first known case was reported at Camp Funston in Fort Riley, Kansas, on March 11, 1918.
When the 1918 flu hit, doctors and scientists were unsure what caused it or how to treat it. Unlike today, there were no effective vaccines or antivirals, drugs that treat the flu. (The first licensed flu vaccine appeared in America in the 1940s. By the following decade, vaccine manufacturers could routinely produce vaccines that would help control and prevent future pandemics.)
Complicating matters was the fact that World War I had left parts of America with a shortage of physicians and other health workers. And of the available medical personnel in the U.S., many came down with the flu themselves.
Additionally, hospitals in some areas were so overloaded with flu patients that schools, private homes and other buildings had to be converted into makeshift hospitals, some of which were staffed by medical students.
Officials in some communities imposed quarantines, ordered citizens to wear masks and shut down public places, including schools, churches and theaters. People were advised to avoid shaking hands and to stay indoors, libraries put a halt on lending books and regulations were passed banning spitting.

With no cure for the flu, many doctors prescribed medication that they felt would alleviate symptoms… including aspirin, which had been trademarked by Bayer in 1899—a patent that expired in 1917, meaning new companies were able to produce the drug during the Spanish Flu epidemic.
The flu took a heavy human toll, wiping out entire families and leaving countless widows and orphans in its wake. Funeral parlors were overwhelmed and bodies piled up. Many people had to dig graves for their own family members.
The flu was also detrimental to the economy. In the United States, businesses were forced to shut down because so many employees were sick. Basic services such as mail delivery and garbage collection were hindered due to flu-stricken workers.
The 1918–1920 flu pandemic, also known as the Great Influenza epidemic or by the common misnomer Spanish flu, was an exceptionally deadly global influenza pandemic caused by the H1N1 subtype of the influenza A virus.
- It struck in three waves across the world. The first wave of the 1918 pandemic took place in the spring of that year, and was generally mild. Those infected experienced typical flu symptoms – chills, fever, fatigue – and usually recovered after several days.
- Its origins are unknown to this day. The 1918 flu was first observed in Europe, America and parts of Asia, before rapidly spreading across every part of the world within a matter of months.
- It did not come from Spain (despite the nickname) Despite its colloquial name, the 1918 flu did not originate from Spain. The British Medical Journal referred to the virus as “Spanish flu” because Spain was hit hard by the disease.
- There were no drugs or vaccines to treat it. When the flu hit, doctors and scientists were unsure what caused it or how to treat it. At the time, there were no effective vaccines or antivirals to treat the deadly strain.
Mar 18, 2020 · The most damaging pandemic of influenza — for Canada and the world — was an H1N1 virus that appeared during the First World War. Despite its unknown geographic origins, it is commonly called the Spanish flu. In 1918–19, it killed between 20 and 100 million people, including some 50,000 Canadians.
The 2018–2019 period marks the centennial of the “Spanish” influenza pandemic, which caused at least 50 million deaths worldwide. The unprecedented nature of the pandemic’s sudden appearance and high fatality rate serve as a stark reminder of the threat influenza poses.
The influenza pandemic of 1918 killed more than 50 million people worldwide. In addition, its socioeconomic consequences were huge. “Spanish flu”, as the infection was dubbed, hit different age-groups, displaying a so-called “W-trend”, typically with two spikes in children and the elderly.
