Is Nasopharyngeal Swab Comparable With Nasopharyngeal Aspirate to Detect SARS-CoV-2 in Children?

To the Editors:

In December 2019 appeared in China a novel coronavirus, designated as SARS-CoV-2, responsible for a pandemic respiratory disease, known as coronavirus disease, with the Italian outbreak from February 2020. Children appear to have milder symptoms and less severe disease.1 The tests currently used for the direct identification of SARS-CoV-2
include specimens taken from the upper and the lower respiratory tract.2,3 Since the use of nasopharyngeal aspirate (NPA) seemed to be better than nasopharyngeal swab (NS) to identify respiratory virus in pediatrics, we decided to compare these methods in detecting SARS-CoV-2 in children.
