Researchers explore difference in reactions to SARS-CoV-2 infection between children and adults

The COVID-19 pandemic has claimed over 2.67 million lives in less than a year and a half. However, it is uncommon in children, with less than 2% of the cases being in individuals below the age of 19. Most of these are of mild severity, with the clinical features of severe COVID-19 being rare in this age group.
