Human beings have never defeated viruses. The most important thing is that human beings have always fought against viruses. In fact, viruses appeared in human life from their ancestors or in caves. However, at that time, all human activities took place in a small area and there was little communication between them, so there was no way to cause a virus. Of course, if the original social virus had become a global epidemic, humans might not be alive today.
For us, the last epidemic was probably Severe Acute Respiratory Syndrome (SARS) in 2003. It took over six months to fight and finally defeat the SARS virus, however, at that time, many many experts. also say similar outbreaks could occur in the future. No, humans will be defeated by a contagious epidemic like coronavirus in 2020. So why is the virus coming backdoes it happen every time it disappears? When will humanity defeat the virus? In fact, we may never defeat viruses, because there may be millions of viruses in nature, but we have only discovered a few hundred. Even though we can't kill them, all we can do is find ways to fight them, just like smallpox. which ravaged the world in the last century. The smallpox virus gradually disappeared from the human world thanks to the discovery of “vaccines”. However, this does not mean complete elimination of the smallpox virus. It is likely to reappear in human society in the future. new viruses will always appear in the human world.
This will be a new type of coronavirus. Many scientists say that in a global warming environment, the frequency of virus outbreaks may be faster in the future because many viruses were otherwise ffrozen birds. accompany the melting of glaciers and the awakening of permafrost. When they mix with humans, animals, oceans, and eventually, after many generations of replication and mutation, they can threaten humans once they spread across species. It must be said that humans know too little about viruses. In the last century, humans first discovered the existence of viruses, as some foreign plants died suddenly on a large scale. Finally, in the laboratory, scientists discovered for the first time. time The shape of viruses and the fact that viruses have been on Earth for at least 4 billion years, it is even possible that they were the first inhabitants of the planet and that they played a role in our evolution.
Now scientists have identified dozens of viruses that can spread between humans. Of course, most of them will not putnot human life in danger. For example, flu viruses are always present every fall and winter. has changed over time, but for some people with particularly strong body resistance, even if they do not take medicine or receive treatment, they will be fine in a few days, but it will be difficult to kill the virus unless to have strong resistance. risk complications in advance. Of course, humans must always be vigilant. After all, many viruses that cause suffering to humans today will not infect humans at first, such as HIV, Severe Acute Respiratory Syndrome (SARS) virus, and Ebola. Viruses mutate during the reproduction process, allowing them to break the limitations between species. Left unchecked, humanity will descend into a major crisis.
