We already have many viruses on our body, some of which will only enter when your resistance is weakened, such as the rhinovirus that causes the common cold, and 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 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 for 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 plagued by viruses like flu, noro, and old picture restoration 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 perish 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. Smart people use this to develop various vaccines. Some infectious diseases, such as smallpox, that have plagued mankind for centuries, can be said to be completely extinct under the condition of widespread vaccination of mankind. Polio, which was common in the past, has also become a rare infectious disease. 1 2 » Read the full text Don't want to paginate?
