The Covid-19 virus, known as the Corona emerging, has become the world's undisputed modern, rapidly spreading and potentially fatal disease, causing millions of people to panic, especially after the World Health Organization (WHO) has escalated its classification from a pandemic to a pandemic.

But, as many doctors assert, this is not the end. Looking at world history, we find that humans have survived and continued after the spread of viral epidemics more fierce than Corona, but they certainly changed the course of history.

Spanish flu
It is not the first epidemic virus and will not be the last. It was preceded and followed by several epidemiological viruses, but it was the most ferocious of them. The Spanish flu spread in the autumn of 1918 in Europe and some parts of America and Asia, and then spread to almost all parts of the globe.

The symptoms of the Spanish flu were very similar to the symptoms of the usual seasonal flu, but they are more fierce and more widespread, so that the number of people affected by it was estimated at 500 million people around the world, equivalent to a third of the globe population at the time, and caused the death of nearly 20 To 50 million people, but the number cannot be confirmed because the statistics were inaccurate, according to Hystery.

It was not known at the time that the cause of this epidemic was ferocious, but it was easily contagious, as it was transmitted through droplets from speaking or sneezing and other usual actions.

Scientists were unable at that time to develop a vaccine to protect and cure the virus, but it ended like all the life cycles of the virus in the world. In the summer of 1919 the epidemic ended without the discovery of a serum, and all who infected it ended up either dead, or their bodies made anti-virus bodies.

Asian flu
The Asian influenza (H2N2) spread to the end of the winter of 1957 in China and East Asia, then it was transferred to America in the middle of summer, and within a few months the flu turned into a pandemic disease that targeted children, pregnant women and the elderly, and by entering the winter the epidemic spread in the southern hemisphere.

Symptoms of the Asian flu are similar to the symptoms of the common flu, such as fever, tremors, and cough, but they are fierce, and deaths from this flu are estimated at about 2 million people in only 18 months when the disease spread around the world.

Survivors of this flu formed antibodies to the virus, and this - in addition to reaching a vaccine against this virus - contributed to limiting its spread and reducing the number of infected and dead people due to infection with it.

Swine flu
There was no epidemic in history. Everyone remembers the H1N1 viral epidemic, which was known as the swine flu, appeared in 2009, and spread throughout the world causing worldwide panic. The virus was causing symptoms similar to the symptoms of traditional seasonal influenza, but it becomes more Ferocity and cause more death.

Prevalence began in the spring of 2009 from Mexico, and moved from it to the United States of America, and within a few weeks it spread to various countries of the world, so that the World Health Organization announced in the summer that people are facing a new global epidemic, and the number of deaths reached more than 18 thousand people in the world.

By scientific observation it was found that this virus does not cause deadly consequences for individuals over the age of 65 years, which means that their body formed a natural immunity from it due to an old infection with a virus similar to the modern axon, and seasonal flu vaccines did not prevent anyone from infection with this virus.

The rate of HIV infection gradually decreased until the World Health Organization announced in the summer of 2010 that infection with the virus is no longer a global pandemic, although the virus still affects so many people and can cause death.
