> “There’s some evidence that the virus SARS-CoV-2, even in asymptomatic, mild cases, may suppress the B cell, which is responsible for antibody production,” he said. “We know that about 85% of the kids have had COVID at some point, could have had a mild decrease in their B cells and perhaps that set him up for more severe RSV, severe rhinovirus, severe adenovirus, and potentially severe influenza.

Or here is a different way the pandemic could have had an effect

> At Yale New Haven Children’s Hospital, Dr. Thomas Murray, associate medical director for Infection Prevention, said the pandemic mask-wearing, hand hygiene, and social distancing kept respiratory infections low. As families have been relaxing those COVID-19 generated precautions, it’s exposing a population of children who previously had minimal exposure to respiratory viruses of all kinds.

> “Virtually every child by the age of two would have had RSV,” he said. “And now we have children who are probably close to 3 years old who may never have had RSV. So the total number of kids that are getting RSV for the first time is likely to be much higher.”
