Children Protection Against COVID-19 at the Pandemic Outbreak

Abstract

Severe Acute Respiratory Syndrome coronavirus 2 (SARS-CoV-2) is a novel strain of coronavirus that is recently identified as an etiological agent for the current pandemic respiratory illness called coronavirus disease 2019 (COVID-19). The disease might have a zoonotic origin and has infected {\textgreater} 19 million people around the globe with {\textgreater} 700,000 deaths. The published data indicate that children are generally less susceptible to contracting COVID-19. Here, we are providing a review on current hypotheses that have tried to explain the low mortality and morbidity rate among children. We believe that understanding the immunological base of children's protection can prevent further spread of the disease.
