Children have very few ACE2 receptors on their cells. The SAR-Cov2 (COVID-19) virus requires ACE2 receptors to attach and infect cells. This is why children rarely get infected, have a low risk of becoming ill, a low risk of spreading the virus to other children or adults, and an almost zero risk of dying from it.
Close to 80% of patients have prolonged illness after COVID-19 infection – the long haulers. These complications are generally seen in those who had mild to moderate infections and in young adults who did not need respiratory support. And some who receive the vaccine have similar complications. Learn how to protect yourself.
