For the brand-new research study, CDC scientists took a look at RSV hospitalization rates throughout 2 various RSV monitoring networks of health centers and medical centers (called RSV-NET and NVSN). They compared the networks’ hospitalization rates in the 2024– 2025 RSV season to their particular rates in pre-pandemic seasons in between 2018 and 2020. The analysis discovered that amongst babies (0– 2 months), RSV hospitalizations fell 52 percent in RSV-NET and 45 percent in NVSN compared to the rates from the 2018– 2020 duration. When the scientist left out information from NVSN’s security website in Houston– where the 2024– 2035 RSV season began before the vaccine and treatment were rolled out– there was a 71 percent decrease in hospitalizations in NVSN.

For a wider group of babies– 0 to 7 months old– RSV-NET revealed a 43 percent drop in hospitalizations in the 2024– 2025 RSV season, and NVSN saw a 28 percent drop. Once again, when Houston was left out from the NVSN information, there was a 56 percent drop.

The scientists looked at hospitalization rates for young children and kids up to 5 years old, who would not have actually been safeguarded by the brand-new items. There, they saw RSV hospitalization rates were really greater in the 2024– 2025 season than in the pre-pandemic years. That recommends that the current RSV season was more extreme, and the drops in baby hospitalizations might be underestimates.
