Abstract

In symptomatic children tested for COVID-19 by PCR during both Delta and Omicron surges, Cycle threshold value medians and distributions in anterior nares (AN) and nasopharyngeal (NP) samples were very similar, suggesting similar yield of NP and AN sampling for SARS-CoV-2 PCR testing in symptomatic children.

Keywords: Ct value; SARS-CoV-2; anterior nares; nasopharyngeal; pediatrics.
