A–C. Monthly RSV test volume (A), patient volume (B) and test positivity (C). Black dots signify observed values, with model fits in magenta. Gray rectangles denote alternating years (from July – July). D. Monthly patient volume from April 2019 – July 2023. Observed patient volume (black) is compared to simulated patient volume under test volumes predicted via pre-pandemic testing data (magenta). Dots signify observed values, with model fits as lines. The prediction interval (gray) depicts patient volume predicted from pre-pandemic patient volumes. A–D. Dashed lines delineate the end of the pre-pandemic phase and the start of the post-emergence phase.
