The Spanish Flu: 15 Facts You Should Know About the Deadly 1918 Pandemic

The Spanish Flu: 15 Facts You Should Know About the Deadly 1918 Pandemic

The Spanish flu pandemic of 1918 was one of the most devastating public health crises in history, infecting around 500 million people worldwide and killing over 50 million. Young adults aged 20 to 40 were disproportionately affected by the Spanish flu. According to research, this is the result of a “cytokine storm” brought on by their robust immune systems overreacting. The World War I mobilization of soldiers and sailors contributed to the flu’s rapid spread along international trade and transportation routes. Prominent people like author Gertrude Stein and artist Gustav Klimt died from it. In 1918, the pandemic subsided in the summer before resurrecting in the autumn with a deadlier second wave. The high death toll was caused in part by inadequate sanitation, overcrowding, and ineffective treatment. Face masks, isolation, and quarantine were among the public health measures used in an attempt to contain the devastating outbreak. Here are 15 important facts you should know about this tragic episode:

1. It Didn’t Start In Spain

The epidemic most likely did not originate in Spain, hence the term “Spanish flu” is misleading. Although its exact origins are unknown, new research indicates that it might have originated in Kansas and been transported to Europe by American soldiers. Newspapers in neutral Spain were free to report the catastrophic Spanish outbreak because there was no press censorship during the war. Because of this, people mistakenly believed that Spain was the epicenter. During World War I, other nations played down the pandemic so as not to lower spirits. Although the exact origins of the pandemic are still unknown, the majority of the evidence suggests that, contrary to what its misleading name suggests, it did not begin in Spain.

2. The 1918 Influenza Pandemic Unfolded In Three Phases

The 1918 influenza pandemic unfolded in three phases. In spring 1918, the first wave was quite gentle. A devastating second wave struck in the autumn of 1918, killing millions of people within months of its arrival. In urban areas and closely packed military camps, the flu spread quickly. Before waning, a third wave emerged in the beginning of 1919. Although not as destructive as the second wave, the final wave was still very strong. Researchers can now explain the flu virus’s shifting nature by understanding that it mutated quickly. The middle wave of the catastrophic 1918 outbreak was by far the most deadly and virulent, made possible by transportation networks and World War I mobilization.

3 It Killed More People Than WWI

The 1918 influenza pandemic’s catastrophic scope far outweighed the heavy casualties of World War I fighting. 1918 saw the global flu outbreak coincide with national troop mobilizations for the war effort. The crowded environment and widespread movement hastened the spread of the virus. Although the Great War claimed the lives of about 19 million people, estimates of the Spanish flu’s death toll vary from 50 to 100 million worldwide. The 53,000 American combat deaths were dwarfed by the over 670,000 influenza-related deaths in the country. While the war took many lives, the flu pandemic that coincided with it proved even deadlier, killing more people in two years than any other known epidemic in history.

4. Young Adults Were Hit Hard

Unusually for an influenza virus, the 1918 pandemic killed a great deal of young, healthy adults between the ages of 20 and 40. Young adults’ immune systems would occasionally mount a strong defence against the virus, which could lead to a potentially fatal overreaction known as a cytokine storm. This deluge of immune cells has the potential to trigger acute inflammation and swiftly escalate into fatal pneumonia. On the other hand, older adults with weaker immune systems did better. The flu killed people in their prime more brutally than the weak elderly, reversing the normal mortality pattern. The 1918 pandemic was especially terrifying because of its effect on young people who had previously been healthy.

5. Symptoms Could Appear Suddenly

Symptoms might strike out of nowhere. Even those who awoke in good health might pass away by evening. Initially, victims would report experiencing typical flu symptoms such as fever, headaches, and chills. But as their lungs filled with fluid, many would begin to turn blue from a lack of oxygen within hours. Unlike most influenza outbreaks that disproportionately affect the very young and the very old, the Spanish flu was unusual in that it had an exceptionally high mortality rate among healthy adults aged 15 to 34.

Scientists now think that the virus caused the immune system to overreact, attacking the body as a result. This “cytokine storm” produced acute respiratory distress by causing fluid to fill the patients’ lungs. The victims basically became submerged in their own bodily fluids. The public was alarmed and hospitals were overrun by the Spanish flu’s ability to quickly kill even the healthiest individuals.

6. There Were Odd Neurological Effects

Strange neurological effects were observed. A few patients reported having insomnia, depression, and mental disorientation. Some people fell into comas. Brain hemorrhage was discovered during autopsy, which may provide insight into the neurological effects of the flu. It is now thought by scientists that the Spanish flu could enter the brain directly and pass through the blood-brain barrier. For some patients, this led to an inflammation of the brain that resembled encephalitis, hallucinations, and violent behavioral changes.

The virus even caused symptoms similar to Parkinson’s disease and killed nerve cells. It was highly unusual that the neurological symptoms were so wide ranging. The high death rate was most likely caused by inflammation and brain damage. The terrifying aspect of the Spanish flu added to the already devastating pandemic was its ability to affect both the brain and the lungs.

7. There Were No Effective Treatments Or Vaccines

Neither vaccines nor effective treatments were available. Maintaining public morale was under pressure while World War I was still going strong. The public health measures were rudimentary: mass gathering prohibitions, school closures, and quarantines. There wasn’t much that medical science could do to stop the flu. The year 1933 would mark the discovery of the influenza virus. In an attempt to save lives, doctors tried every treatment imaginable, including aspirin, herbal remedies, and bloodletting, but nothing seemed to work. Patients were suffocating from fluid-filled lungs in emergency flu wards, so oxygen tanks were hauled in. Despite working nonstop, doctors and nurses could only watch helplessly as patients passed away. The pandemic’s terror and devastation were exacerbated by the complete lack of an effective treatment. Doctors could only advise rest, clean air, and healthy

8. More US Soldiers Died Of Flu Than In Battle

The flu killed more US soldiers than combat. Due to their crowded and unhygienic conditions, military camps were ideal places for influenza to spread. Ten thousand American soldiers lost their lives in combat, and an estimated 43,000 died from the flu. During the pandemic, flu affected 40% of US Navy personnel. In the trenches of the European battlefields, the flu also spread quickly. Soldiers became sick, rendering entire regiments non-operational. The temporary cessation of battlefield operations by both parties had an impact on the war plan. In an attempt to prevent the flu from destroying their soldiers, the Americans, Germans, and Allies began medical research. But no effective defenses or remedies could be discovered, so soldiers were left utterly exposed to the virus’s destructive power.

9. It Disrupted Daily Life

It made life more difficult. Theatres, shops, and schools were closed. When operators and messengers became unwell, delivery and telephone services were discontinued. High mortality rates overwhelmed funeral directors in certain areas, resulting in a build-up of bodies. There had to be mass graves dug up temporarily. Due to the Spanish flu, there was a great deal of social unrest as public meetings were outlawed, saloons and churches were shut down, and quarantines were enforced. Illness kept a lot of people from working, which had a serious influence on vital services like food distribution, law enforcement, and healthcare. The World War I soldiers’ morale and mobility deteriorated.

Many kids were left orphaned because parents passed away. In certain countries, such as the US and India, life expectancy has decreased by ten to fifteen years. Unusual public health measures, including the requirement for face masks, the division of work hours, and the prohibition on spitting in public, were brought about by the Spanish flu. The pandemic drastically changed many people’s daily schedules and interpersonal relationships.

10. Not Everyone Took It Seriously

It wasn’t taken seriously by everyone. Public health officials tried to caution the public by covering sneezes and coughs. However, sometimes the urgency of war and the need to keep morale high overrode health messaging. Some people wrote the outbreak off as a small annoyance. At first, a lot of officials and media people overestimated the pandemic or downplayed it.

Still, the tone became more urgent as the death toll increased. Some politicians, companies, and religious organizations continued to be skeptical, and they opposed public health orders that closed theatres, schools, and churches. Extremists even went so far as to say that the government was fabricating the pandemic in order to manipulate the public. There were rumors circulating that spies were dispersing infections. Profiting from fear, advertisements promoted folk remedies and ineffective medications. Mask orders varied in terms of compliance and enforcement. Even though some complained about lost wages or liberties, most people were ultimately persuaded to take precautions due to the sheer number of Spanish flu deaths.

11. There Was Stigma And Denial

Both denial and stigma existed. Some people avoided seeking treatment because they believed their illness was a death sentence and there were no cures. Out of embarrassment, some denied having the illness. The use of euphemisms like “the grippe” by public officials replaced an open confrontation with the deadly pandemic. Many were embarrassed to acknowledge they were infected, worried about being rejected or looked down upon. In order to shield families from stigma, doctors frequently misdiagnosed flu cases or entered erroneous causes of death on death certificates. The risk of infection increased as people avoided hospitals and covered up sick family members. Ethnic groups that were blamed for spreading disease gave rise to xenophobia. Companies refused to close due to workplace outbreaks. During times of war, governments hid flu statistics to keep the populace optimistic.

The public health response was hindered and the pandemic was allowed to worsen by this stigma and denial. However, as time went on and people realized that anyone could contract the Spanish flu, stigma decreased as a result of open acknowledgment and public education campaigns. Overcoming the pandemic required more open communication about preventive measures and more accurate reporting of infection rates.

12. It May Have Originated From Birds

It might have come from birds originally. Although the precise origin is still unknown, increasing genetic evidence suggests that it originated in birds. Unusual proteins present in the virus were not discovered in human flu viruses at the time. Bird flu was also killing them. According to recent analyses, the virus most likely underwent a mutation and made the direct leap from birds to humans just prior to the 1918 outbreak. It is unknown where the first animal-to-human transmission occurred, but it most likely happened in North America. Some people believe that the deadly avian flu outbreaks in East Asia are the source of the Spanish flu, while others attribute it to Kansas’s poultry farms.

Asymptomatic carriers of influenza viruses, wild aquatic birds can serve as reservoirs for new strains of the virus. During World War I, there was probably close contact between humans and livestock, which helped a mutated avian virus adapt to human hosts. After the virus started to spread, crowded military camps and more international travel made it easier for it to do so quickly. Because of the early 20th century’s lack of scientific influenza surveillance, determining the source of Spanish flu has proven challenging. Modern genetic techniques applied to preserved tissue samples continue to shed light on the origins and evolution of the deadly 1918 virus.

13. There Was A Connection To Swine

There was a swine connection. According to a different theory, the virus originated in swine and spread to humans because it shared genetic similarities with flu viruses that pigs can contract from birds. Swine flu genes were also present in the virus. It’s possible that pigs acted as “mixing vessels” for the deadly new influenza strain that was transmissible to humans, combining human and avian influenza strains. This animal-human viral assortment was made possible by close hog-human contact on farms. The swine flu can adapt because of the similarities between the human and swine respiratory epithelium.

Furthermore, during World War I, pigs were transported all over the world, which might have spread new strains of the flu. But it’s still unclear exactly when and where swine flu mixed with human transmission occurred. Although the 1918 virus’s genetic heritage suggests swine influence, there isn’t enough concrete proof that a pig-to-human jump caused the pandemic to start. On the other hand, it’s possible that early genetic sequencing missed some avian source strains. Whatever its precise source, the Spanish flu showed that influenza can spread across species from animals to people, underscoring the importance of vaccinating livestock against the disease. In order to prevent future pandemics caused by zoonotic influenza, it is still imperative to conduct ongoing animal surveillance and observe human-animal interactions.

14. Pandemic Prevention Systems Arose From Its Legacy

Systems for preventing pandemics emerged from its legacy. Better monitoring and communications networks, as well as international organizations such as the World Health Organization, emerged in the aftermath to identify emerging pandemics earlier. The 1918 influenza pandemic’s high death toll and devastating socioeconomic effects made clear the need for better international public health infrastructure and coordination. In the decades that followed, global gatherings and accords made cross-border information exchange and disease monitoring possible, thereby enabling the early detection of epidemics. Field epidemiology has received funding in order to facilitate quick action in the event of future pandemics. In order to create vaccinations and treatments, new virology research centers investigated the genetics and transmission of influenza.

In order to identify new flu strains, WHO established a global influenza surveillance network in 1947. This network periodically gathers data from more than 100 countries. Although it is still challenging to anticipate and completely prevent influenza pandemics, the mechanisms put in place following 1918 are designed to ensure that no one is ever caught off guard by the rapid global spread of a pandemic. These very systems—surveillance and response—were put to the test in a big way when COVID-19 struck, providing an additional unique respiratory pandemic.

15. We’re Still Not Immune

We are still not impervious. The 1918 virus gave rise to all subsequent flu strains and pandemics. There are still genetic remnants of the 1918 pandemic present in current seasonal flu strains. The importance of flu shots and public health readiness is increased by our ongoing susceptibility. Over the past century, the 1918 influenza virus has continued to circulate in humans, resulting in new pandemics and yearly seasonal flu outbreaks. This virus also established an enduring viral lineage. Rapid influenza virus mutation allows for viral adaptation and immune system evasion in successive generations.

The 1918 strain of the virus was responsible for later flu pandemics in 1957 and 1968, as well as the 2009 swine flu pandemic. Annual flu shots offer crucial, if sometimes insufficient, defense against this immunologic virus and its potentially fatal pandemic potential. The population still has no stronger defense against influenza viruses that are descended from the 1918 pandemic, even a century later. Experts in virology warn that another significant flu pandemic as deadly as the one that struck in 1918 is overdue. They emphasize the need for ongoing watchfulness and public health preparedness to identify and quickly address the outbreak using resources like vaccines and antivirals that were unavailable a century ago.

 

Deep scars were left by the Spanish flu pandemic of 1918, which also influenced public health for the following century. It is easier to see the severe toll infectious diseases can have when one is aware of their causes, trends, risk factors, and effects on society. Threats still exist, even though medical advancements, international cooperation, and surveillance systems have helped us prepare for pandemics much better.
