More recently, more details about the Corona virus and the stages that the person has been infected with have begun to unfold, providing some answers about how the virus is transmitted inside the body, and what are the most threatened organs. The German websites, "His Identity" and "Deuchi-Villa", quoted virologist Matthew Freeman as saying that there are three stages that a person with Coronavir virus passes, starting with the spread of the virus in the respiratory system, which affects the cephalative cells producing mucus, which are necessary to maintain Respiratory system and lungs. The virus infects the cilia of the cells, then begins to kill them, and the viruses then collect in the lungs.
In the second stage, according to specialist Freeman, who works at the University of Maryland School of Medicine, it is the body's interaction with these substances and viruses with masses of immune cells, which are supposed to kill the virus. At best, the immune response contributes to containing the virus completely.
On the other hand, the danger lies when the response of the immune system to the injured is exaggerated, as in this case it kills healthy tissues, which causes the immune response to get out of control.
In the third and final stage, the lung is heavily damaged and filled with fluid, which leads to respiratory failure, and in the worst cases this results in the death of the patient with the Corona virus. Moreover, the uncontrolled immune response can damage other parts of the body.
