Why don't symptoms appear if coronavirus has already entered the body? The portal tells about it. Yellmed.ru with reference to Inverse.
The probable causes of the absence of symptoms were named by Catherine Bowhemin, professor of virophysics at the Ryerson University of Canada.
- The immune system has been reacting for too long. Symptoms will appear, but later.
- Immunity, on the contrary, began to act very early - the virus “defeated” quickly, prevented it from “multiplying”, and the symptoms did not even have time to develop.
- The concentration of the pathogen in the body is very small, insufficient to cause a vigorous immune response and symptoms appear.
“Imagine that a virus is an invasion of enemies,” explains Katherine Bowhemin. - If the invaders enter one at a time and you immediately notice them, then it will not be difficult to push the aggressors out of the house. You will not even suffer. Accordingly, there will be no symptoms. ”

Situation: the virus has multiplied, but there are still no symptoms
This is a dangerous situation. Firstly, such a person will actively infect others without suspecting it. Secondly, sooner or later the immune system will have to give an answer, and immediately to a huge number of “enemies”. And this answer can be very stormy.
Sometimes immune cells are so aggressive that organs suffer more from their activity than from the actions of the virus itself.
As you can see, it is important to distinguish between symptoms as a result of the action of SARS-CoV-2 and symptoms caused by the immune response to the virus.
Coughing and fever are clear indicators that immune cells are fighting the virus. But if you feel great, this does not mean that there is no struggle in the body. It just is not felt.
When immunity nevertheless “loses” to the virus, respiratory failure, pneumonia develop, in severe cases - fibrosis, damage to various organs.
