Dec 2022 Respiratory syncytial virus (RSV) manifested earlier and in significantly higher numbers at the outset of the 2022-2023 viral season. Children have been most visibly affected by this year’s spike in RSV; the hospitalization rate during the early months of winter for children aged 0 to 4 years rose to 61.5 per 100,000 in mid-November, substantially higher than last year’s early winter peak of 13.3 per 100,000 on December 11, 2021. Although hospitalizations for children 0 to 4 years of age dropped to 17.9 per 100,000 as of November 26, 2022, that rate still outpaces the rate for approximately the same time last year.2
