On Tuesday's "CNN Newsroom," CDC Director Dr. Rochelle Walensky stated that part of the reason why the healthcare system is facing a large influx of RSV cases is "because of COVID, because of all the mitigation strategies that we've had over the last several years," "we have several years of children who've never seen RSV before. And because of that, we have these layers and more children who are requiring hospitalization than we see generally in a given season."
