Spanish flu is often overshadowed by its most popular counterparts, such as Ebola and the Black Plague. In many ways, however, it was far more lethal than anything we saw before or after. An estimated one-third of the world's population became ill and at least 50 million people died. The physicians of 1918 did not even know what it was because they did not properly understand viruses and influenza pandemics.
Although Spanish influenza represents such a world-changing event, it is surprisingly underrepresented in popular world history. While we understand that other important things – such as the Russian Revolution and the First World War – were also going on around that time, they still are not comparable to what many historians call the "greatest medical holocaust in human history". [1
Since it is the "Spanish flu", many of us assume that it comes from Spain. His name is the main reason why we still blame Spain for something he had nothing to do with. Although we do not know where the flu came from, we know for sure that it was not Spain. In fact, the number of cases in Spain was lower than in many other countries.
It is referred to as Spanish flu, as Spain was one of the first (possibly the first country to comprehensively report it.) Because they were neutral in the First World War (they had their own cause), theirs was Press freer than other nations, countries such as Britain, the US, and Russia, all involved in the war, kept the news of the flu to a minimum in order to maintain morale Accused of messengers when people started to attribute the flu to Spain, even though it was honest about it. 
9 We somehow ignored it at that time
As mentioned earlier, the Spanish flu was a pandemic like no other that we have ever experienced in our history, and spread in just a few months in almost all parts of the world, for such a great medical fear one might think that s It would be the covers of all the leading newspapers of the time.
In reality, we only cared about the First World War. At the time, it was the biggest and only global conflict that people had seen. It was a more catchy course than dying from the flu, as "people who died of disease" did not bring the latest news in 1918, but "people who died of chlorine gas in combat." 
8 It was not a towering flu
The mere rate of infection and the number of deaths in such a short time really do not sound like something a normal flu virus can do. It is always believed that Spanish flu is a supernutrition disorder for which we simply did not have a cure that came from nowhere and decimated whole sections of our population.
However, recent studies have found that the virus is not "more aggressive or dangerous than any previous influenza epidemic."  The main causes of the fatality were overcrowding and poor hygiene due to warfare, with many people around the world due to the geopolitical conditions at that time in confined spaces such as military barracks and refugee camps, which allowed the virus to spread much more easily than usual.
7 Resurrection Of The Virus
Spanish influenza has been the subject of studies from the beginning, Mostly because of their fast-paced and deadly disease, despite all our efforts to understand it, for a long time we had no idea what it was causing or what type of virus it was all about, back in the 2000s, when some scientists it isolated and found out that the restoration of these conditions in the Laboratory was the best course of action.
In a move that could have been very, very wrong for humanity, some researchers obtained frozen specimens of the infected body and kind of activates it in the lab to see what it does. They were surprised to find that the virus was similar to the H5N1 avian influenza virus, which was responsible for a series of deaths in Asia last year. 
These are messages. Bird fluors generally become more pathogenic with each further outbreak, and if ever humans are really well infected, the resulting pandemic could be worse than the Spanish flu.
6 The flu virus was not the main killer
One of the biggest concerns about Spanish flu is that we do not really know how to tackle it, even with modern medical technology. On the one hand, today various pathogens are rapidly developing immunity to antibiotics and other medicines, mainly due to our overwhelming confidence in such medicines to cure even simple diseases.
More importantly, influenza viruses are not the problem per se. It's the other medical complications we should really worry about. Studies have shown that most deaths during Spanish flu are due to bacterial pneumonia that occurred just after the virus. After the flu had successfully weakened the immune system of those affected, their bodies constituted a fertile breeding ground for the bacteria. 
5 Why Healthy Young Adults Affected
A very special aspect of the whole thing was the fact that Die Spanish flu mainly affected healthy, young adults who participated most actively in the war. (It's probably no coincidence.) It was one of the most confusing parts of anything, since it went against everything we thought we knew about influenza outbreaks or diseases in general. Young adults should be able to ward off illnesses better than other groups such as the elderly, although this was clearly not the case this time. So what is there?
According to recent research, this is quite plausible. People born between 1880 and 1900 – the most affected population – never developed immunity to the right type of flu virus. The most common influenza in childhood was quite different from Spanish flu. Those born in the early 19th century were exposed to influenza viruses more akin to Spanish flu, and therefore had better immunity. 
4 Aspirin might have made it worse
There is no doubt that Spanish flu was one of the deadliest events in human history. It was a humiliating experience, and no one could stop it, though it would be a bit unfair to say that we had no complaints whatsoever.
According to some scientists, many of the early flu deaths were possibly due to aspirin. You see, at that time we had little idea what a normal dosage of aspirin should be. We used it like water and only gave it to patients in the hope that they would feel better because we had no better ideas. The scientists hypothesized that "a significant proportion" of these deaths were due to salicylate poisoning, as we had not yet figured out how much aspirin people can safely consume. 
3 Corpse Exhibitions
Part of Spanish flu stories is the horrors of the whole. Imagine buying groceries and seeing decaying bodies and critically ill people on the side of the road before you even get to the store. Of course that's the case if you were lucky enough not to catch yourself, as the chances were quite high.
One particularly horrible aspect was what to do with all the dead. The number of deaths in the US was so high that it was not always possible to build coffins for all, and the dead were buried directly in the ground. This was called "planting".
If that was not bad enough, many buildings also served as temporary morgues to keep the dead. In a particularly scary case, corpses were displayed at the windows of high school in West Pittston, Pennsylvania, so that relatives could pay their respects from a safe distance.  (The school had already been closed to prevent the spread of corpses to the disease.)
2 It could have originated in China
Besides being an unprecedented medical emergency , the Spanish flu was also quite puzzling. The biggest question was where she came from. (As we have already noted, this is not Spain.) If you know where it comes from, you need to identify the circumstances that led to such a serious outbreak, and make sure it does not happen again. Although this is a question we may never be able to definitively answer due to the lack of medical records from that period, some historians believe that the Spanish flu comes from China.
Mark Humphries of the Memorial University of Newfoundland says the virus was shipped to Europe with some 96,000 Chinese workers employed to work for the British and French forces. While he admits that we need more samples of the virus to truly confirm his lineage, other historians find this hypothesis plausible. China had fewer victims of the flu, suggesting that their population was previously immune to it. 
1 One of the Greatest Threats to Human Life We think of threats to life on Earth, we always think of things like nuclear war or asteroids. This is probably because these events sound much more destructive and deadly than a mere illness, not to mention that today's medical care is much more advanced than before. The spread of the pandemic is still high on the list of things that can wipe out human civilization. Of course, our quarantine methods and medicines are well able to deal with such threats, even though we have not seen anything like the Spanish flu since 1918. The same flu would spread much faster today because the world is much more connected than it was then. The virus could also be much more resistant to our drugs.
It is estimated that a virus with a similar pathogenicity as the Spanish flu would kill more than 100 million people today, and there is little we can do to curb it.  We do not say we should all panic, but world governments are well advised to focus a little more on this threat.
