However, the relative contribution of infants and children to community transmission is not known. Data from China suggest that children were infected early in the outbreak [3]. A report published in this journal described the presence of a high nasopharyngeal (NP) viral load of severe acute respiratory coronavirus 2 (SARS-CoV-2) in a well infant [4]. Whether this observation is generalizable to symptomatic infants, and how it compares to NP viral loads in older children and adolescents, is not known. Studies in adults have demonstrated a positive correlation between viral load and COVID-19 severity [5]. While some data have suggested a higher disease severity in infants [2, 6], how NP viral load correlates with severity across the pediatric age spectrum has not been firmly established …
