Coronavirus (COVID-19) Mechanism and Self-Rescue Measures (2)
What is free radical?
Free radicals are a kind of very active chemical that easily reacts with other substances, once reacted, it can denature proteins and damage DNA. It is very destructive but actually it is our own immune cells, such as neutrophils, mast cells, … The function of these cells is to eliminate bacteria and viruses that invaded our body, but these cells have no distinguishing function, when they destroy the virus, they also cause the damage to the cells of our body.
When the virus enters a person’s body, his immune system fights back and he will have a fever. Fever is a defensive response. When a patient has fever, in his body neutrophils and mast cells release a lot of free radicals. There are several kinds of free radicals, peroxide free radicals are more powerful, and some other hydroxide free radicals are very easy to react with proteins and DNA. (Forgive me if the names of the cell is incorrect. I studied cell biology many years ago and returned the knowledge to my teacher. Gina) The reaction will cause cells die. That’s how the patient’s heart, lungs, liver, and kidneys are damaged. Medical research has found that this to be a common phenomenon. No matter what the virus is, its pathology is similar. For example, hepatitis virus infects liver cells, it is not the virus itself that causes liver cell disease but when immune cells fight back, they also killed liver cells and lead to liver necrosis. There are three development stages of Coronavirus.
The first stage is early infection stage. The symptoms include fatigue, soreness, and lack of appetite. At this stage, the virus multiplies in the body. Viruses are not the same as bacteria. Bacterias can produce on their own, the virus must rely on the human cell system to multiply. The virus left on some subjects will die in certain period of time.
At the second stage, the immune system fights back and high fever develops. Some people have a fever for 3-5 days. The immune system produces excess free radicals when it clearing the virus. Free radicals cause severe damage to the heart, lungs, liver and kidneys. After the fever, the amount of virus in the body is already very low. Now the virus is not a problem, the problem is the major organs are severely damaged.
In the third development stage of coronavirus, the damage to the major organs lead to symptoms of respiratory failure, heart failure, liver failure, and renal failure. At this stage, some older and frail are quickly dying. Using a ventilator to sustain life, it is not a cure. People of good constitution may survive.
