Researchers explore difference in reactions to SARS-CoV-2 infection between children and adults The coronavirus disease 2019 (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. A new and timely study, which was released on the medRxiv* preprint server, explores the differences in the response to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection in adults vs. children to help understand how the disease develops and progresses.
