In COVID-19, the severe effects of pneumonia will not spread evenly among people of all ages. Young people-except those with basic health problems-seem to be escaping the worst effects of this epidemic. An early study showed that only 65,438+00 of more than 700 children who were known to have close contact with confirmed cases or whose family members were recently diagnosed with infection were positive.

All the children in 10 are under 15 years old, and none of them need respiratory support or intensive care. An early study published in the journal Pediatrics (which may be revised) pointed out that there was only one death among more than 2,000 confirmed and suspected cases in COVID-19. In order to infect animals or humans, viruses must hijack the cellular mechanism in order to start replication. This means that the virus first needs to find an entrance into the cell. There is an important similarity between the two coronaviruses causing SARS and COVID-19: they use the same keyhole to enter cells, which are called ACE2 receptors. Kalum semple, a professor of child health and disease outbreak medicine at the University of Liverpool, speculated that the ACE2 receptor in children's lungs could not match the key of the virus well.
