The main danger of coronavirus in the human body is the uncontrolled activation of immune cells in the focus of inflammation.
Scientists have found that coronavirus is dangerous due to an overreaction of the immune system to an infection that has entered the body, according to a study in the journal Frontiers in Public Health.
According to the assumption of Chinese experts, during the disease, one of the proteins penetrates the cells of the alveolar epithelium, causing a cytokine storm – uncontrolled activation of immune cells in the focus of inflammation.
In severe cases, such a reaction can lead to lung damage and septic shock, which causes organ damage.
As an example, the authors of the publication cited statistics according to which 67.3 percent of severe patients with COVID-19 develop acute respiratory distress syndrome, almost 29 percent report acute damage to the kidneys or liver, and 23.1 percent have heart damage.
It was reported that Italian scientists from Harvard University calculated the actual mortality from coronavirus.
Recall, scientists have established why older people are more often sick and die from coronavirus.
