The susceptible group of the new coronavirus is all people, not children who are not susceptible to infection. It is true that there are not many cases of children being infected at present, unlike chicken pox, scarlet fever and measles, which are predominantly infected by children. This is mainly because the community as a whole is more preventive, children are isolated at home and do not go out much, and schools and kindergartens are not in session nowadays, so the means of transmission for children have been cut off. In addition, children generally do not have chronic illnesses or other systemic diseases, so even if they are infected, it is difficult for them to develop serious illnesses. Source: Dr. Yurai
