Beware of the re-evolution of Timy Kerong! Multiple new variants spread in the United States. Worldwide, if the virus cannot be "cleared", it means that the mutation of the virus can never be "blocked". Human epidemic prevention and control is always on the road!
It seems that human beings have never experienced such a powerful virus from ancient times to the present; contemporary people are smart, and the virus seems to be smart. Contemporary people are smart because of the development of science and technology, and is the virus also a product of science and technology? I don't think nature will naturally produce such a strange virus.
If such viruses could evolve to be carried and transmitted by birds and animals, it would be really more troublesome. Because even if the global countries work together to prevent the epidemic, it is impossible to control the migration distribution of migratory birds.
The overall picture shows that humanity is experiencing a huge race against the virus, and more difficult scenes are still waiting for us to overcome together.
