"Most viruses, including AdV and RV/EV, were more frequently detected in younger children, whereas SARS-CoV-2 was more frequently detected in adults." This mirrors what we have known for a long time. There are certain viruses which children amplify (flu, RV),others which adults amplify (SC2).

Over 24 weeks, 55% of the participants had a respiratory virus detected at least once, although they don't always need to symptoms. The youngest (ages 3-8) were most likely to be positive for a virus AND most likely to have symptoms; if staff were virus+, it was likely to be symptomatic.

The study is a mix of surveillance and symptom-responsive swabbing for adenovirus (AdV), human metapneumovirus (HMPV), influenza A and B, parainfluenza 1 to 4 (PIV 1–4), respiratory syncytial virus (RSV), rhinovirus/enterovirus (RV/EV), SARS-CoV-2, and sCoVs 229E, HKU1, NL63, and OC43.
