Lower nasopharyngeal viral loads in pediatric population. The missing piece to understand SARS-CoV-2 infection in children?

SARS-CoV-2 virus infects children but, contrary to other respiratory viruses, children tend to be asymptomatic or to have less symptoms than adults and are rarely the index case in household transmission chains.

Description
Summary:SARS-CoV-2 virus infects children but, contrary to other respiratory viruses, children tend to be asymptomatic or to have less symptoms than adults and are rarely the index case in household transmission chains. The aim of this study was to compare the relative viral loads in nasopharyngeal samples from children aged 0 to 17 years with those of an adult population. We selected 126 positive nasopharyngeal samples from children. Relative viral loads were measured by RT-PCR and the comparative ∆Ct method using primers and probes targeting the viral gene E and the human RNAseP. Relative viral loads were significantly lower in the children population than in the adult one.
