The bubonic plague bacteria are spread by fleas that live on rats, which in turn infect humans. From the trading ships, the plague quickly spread to Europe.

At that time, the relatively backward medical system was not enough to fight this epidemic. In addition, Europe at that time was in constant war, people died everywhere, no one cared and managed, so it created conditions for the disease to spread quickly. The result is Black Death plague spread throughout Europe, spread to Asia, becoming the most terrible pandemic in the world.

With a total of 74-200 million deaths – more than half of Europe’s population, Black Death Plague It is still the deadliest and leading pandemic by far Top 10 scariest pandemics in world history.

Details:

• Time: 1346-1352
  
• The center of the pandemic: Europe, West Asia
  
• Bacteria: Yersinia pestis
• Number of dead: 75-200 million won
  

Spanish flu was a global pandemic, occurred in 1918. The main cause of this terrible pandemic was the A/H1N1 virus, to this day mankind is still terrified of this strain of influenza (AH…N.. .).

In 1918, a new strain of influenza was discovered, derived from avian and seasonal influenza in humans, infecting pigs to create a new strain of influenza. This new strain of flu has the ability to spread as quickly as bird flu and have a high mortality rate like seasonal flu. Quickly, Spanish flu has spread globally, even to the most remote areas such as the islands of the Pacific Ocean or the Arctic. Part of the reason for the rapid spread of the pandemic is considered to be World War I, which sent too many soldiers and refugees from one country to another, leading to an uncontrolled spread. .

It is estimated that up to 5% of the world’s population has been infected with influenza A/H1N1 in Spanish flu. Of those infected, up to 100 million people have died. This is the first time the influenza A/H1N1 strain has been known to humans. To this day, A/H1N1 and viruses of the same family as A/H2N2, A/H5N1… are still scary viruses, even though humans have developed a preventive vaccine.

Asian bird flu The years 1889-1990 caused the most terrible disaster in the world. This is a bird flu, spread from birds to humans, so it is often called “avian flu”.

They only knew that it was influenza A virus, and the study suggested that they could be H2 or H3. It was not until later, when the influenza A/H1N1 pandemic broke out, and studies on influenza A strains developed, that medical scientists found evidence, thereby being able to determine the cause of the disease.

HIV / AIDS Surely the phrase is no longer strange to readers. Many readers may wonder why HIV / AIDS is considered a pandemic. Reality, HIV / AIDS has been called an “epidemic” by the WHO. HIV / AIDS are also caused by viruses, which infect and spread from person to person. The only difference is that HIV / AIDS did not break out in a scary way at a time, but quietly killed people through time, from 1986 to the present.

HIV / AIDS It is a disease caused by the HIV-1 virus. HIV-1 virus parasitizes the human body cells, causing the immunodeficiency syndrome, in the final stage, AIDS, the patient will die because the immune system is too weak, unable to fight common diseases. often.

HIV-1 virus is not spread through the air (such as influenza A virus, SARS) or surface contact (such as ncovid-2019) but is spread mainly through sex, blood and genetics. It is estimated that the highest transmission rate of HIV/AIDS epidemic is through sex, then blood. This explains why drug addicts who use needles are more likely to be infected HIV / AIDS very high.

Discovered in 1986, HIV / AIDS has killed 32 million people and still has no cure. This is considered the disease of the century – the most feared and deadly of all diseases. The reason is because the infected person HIV / AIDS will almost certainly die, in addition to the subjectivity in prevention, as well as the problem of drug and sex crimes that have become a global pain.

To this day, fighting with HIV / AIDS is still a difficult problem because this pandemic shows no sign of stopping. In 2018 alone, 770.000 people died from HIV / AIDS. Although this number has dropped significantly from the peak of the epidemic (in 2010 with 1,2 million deaths), it is still a high number, with a pandemic that has existed for more than 30 years.
