He is also the great evolutionary biologist Lynn. A follower of Lynn Margulis (1938-2011), who promotes her thoughts on symbiosis and holobionts in many places in the book, makes us realize that we and the virus are actually partners in forming mutual cooperation relation. We already have many viruses on our body, some of which will only enter when your resistance is weakened. For example, the rhinovirus that causes the common cold, they can only survive in the upper respiratory tract. It is also a respiratory infection virus, but SARS-CoV-2 has no limits and boundaries.
The organs they infect may not be capped, leading photo restoration service to various strange symptoms and complications; as mentioned above, there are many zoonotic infectious diseases that can be transmitted across species , Bats are the common natural host of many human viral infectious diseases, but there are also viruses that are very special to humans, such as the polio virus commonly known as polio virus, which only exists in humans. I myself have been ravaged by viruses like flu, noro and dengue, and of course I hate them to the core, but they don't have feelings for us.
They make people sick or die, and they are simply subject to selfish genes - just copying themselves like crazy. Those symptoms of sneezing, coughing, vomiting and diarrhea, bedridden, etc., are just good for their transmission. If they kill the host too quickly, they will also die together, so infectious diseases with too high mortality rarely lead to large-scale outbreaks. Of course, we have to sit still, and if we survive, our immune system will hold a grudge.
