Children do not - why the risk is low?

Children can also be infected with coronavirus. But their risk is low. Even if they are infected with corona, they do not have to suffer much. In most cases, it is limited to a slight cold-cough-fever or weakness. He recovered in a few days. Experts have a number of studies on why this happens. An analytical article by Apoorva Mandavilli (Apoorva Mandavilli, September 25, 2020) has been published in the New York Times Science Times. Experts believe that when infected with corona, babies use the immune system to kill the virus at birth. So there is not much damage. As soon as they detect the presence of an unknown pathogen, a branch of the child's immune system becomes active and attacks the virus. This reaction occurs within an hour of finding an unknown pathogen in the body. That's why coronavirus can't do much harm. Immune systems in babies work very quickly. Adults cannot take action so quickly. The study was recently published in the journal Science Transnational Medicine.

Children have another advantage. According to a report published on the BBC website (1 April 2020), one of the reasons why children acquire this special skill may be the characteristics of their body cells. They have lower ACE-2 receptors (angiotensin converting enzyme II, ACE-2) in the cells near the lungs at the bottom of the respiratory tract and more at the top of the respiratory tract. Coronavirus infections cannot occur without ACE-2 receptors. This is because coronavirus infection is successful only when its filaments twist the ACE-2 receptor on the outer lining of the body and enter the cell to take control.

The virus then continues to reproduce effortlessly. But without that receptor, the virus cannot enter the body cells and is destroyed. Because babies have some of these receptors in their noses, mouths, and throats, their infections usually spread to the upper respiratory tract, but not to the lungs. Because, there is almost no ACE-2 receptor.

Even so, owning one is still beyond the reach of the average person. So be careful. Rather a little more caution is needed. Because, children are very weak in movement. It is better to keep an eye on them. General hygiene also applies to children.
