Why this site exists

RSV puts more US infants in the hospital than any other illness. Every fall, parents of newborns navigate a confusing web of information: Is RSV going around right now? Should my baby have gotten Beyfortus? When is RSV season where we live?

No single place answers those questions simply. The CDC has surveillance dashboards — but they're built for epidemiologists, not exhausted parents at 2am. Hospital and manufacturer sites are product-focused. News articles are episodic.

This site exists to give parents one clear, data-driven answer: Is RSV active near us right now? And then to explain what that means and what to do about it.

The data

Activity levels are derived from CDC HHS Protect hospital admissions surveillance data — the same underlying data source used by public health officials. The data captures weekly new RSV-associated hospitalizations by state and jurisdiction, updated weekly. We translate those counts into a 0–5 activity scale calibrated to national and state-level population baselines.

RSV data is inherently less fine-grained than flu surveillance (which has the ILINet outpatient network). Hospital admissions capture the severe end of RSV burden, not total community spread. Think of the activity level as a signal that RSV is circulating and hospitalizing people in your state — not a count of total cases.

Medical information

This site is not a medical resource and does not offer medical advice. The immunization timing information (Beyfortus, maternal Abrysvo) is based on publicly available CDC and FDA guidance as of 2026, but guidelines evolve. Always confirm timing and eligibility with your pediatrician or OB.

The symptom triage section is intended to help parents recognize warning signs, not to replace clinical evaluation. When in doubt, call your pediatrician. If your child is struggling to breathe, call 911.
