A clear answer to the question parents ask every fall.

What this site is

It's an RSV activity tracker built around a real answer. Not "RSV season typically runs October through March" — that's a calendar sentence. This site answers: is RSV actually circulating in your state right now, how active is it, and what does that mean for a newborn, an expectant parent, or an adult 60+?

The verdict at the top is driven by weekly CDC hospital admissions surveillance data. Below it, the page walks through protection options, what's going around, how the season is trending, and what to do at home if RSV hits — each section designed to answer a specific question a real person has when they're worried about their infant or an upcoming birth.

Why we built it

RSV puts more US infants in the hospital than any other single illness. Every fall, parents of newborns navigate a genuinely confusing information environment: Is RSV going around right now? Should my baby have already gotten Beyfortus? When is RSV season where we live? Is this just a cold, or is this something worse?

No single place answers those questions simply. The CDC has surveillance dashboards built for epidemiologists. Hospital sites are system-specific. Manufacturer sites are product-focused. News articles are episodic — they cover RSV outbreaks as events, not as an ongoing season to navigate. None of them tell you the current activity level in your state, whether the window for the maternal vaccine has passed, or which symptoms in your infant mean "call the doctor now" vs. "go to the ER."

This site exists to give parents one clear, data-driven answer — is RSV active near us right now — and then to explain what to do about it in plain language, calibrated to their specific situation.

What's on the page

At the top you get a plain-language verdict for your selected state — YES, VERY LOW, or similar — color-coded by severity. The verdict reflects the current 0–5 activity level derived from CDC hospital admissions data for that state.

The Protection Window translates the current date and your state's RSV season timing into specific immunization guidance for four audiences: newborns and infants (Beyfortus), expectant parents at 32–36 weeks (maternal Abrysvo), adults 60+ (Abrysvo or mRESVIA), and people with chronic conditions or compromised immunity. The guidance reflects publicly available CDC and FDA recommendations as of 2026 — not medical advice, and subject to change. Always confirm timing and eligibility with your pediatrician or OB.

What's Going Around is a ring chart showing current RSV, flu, and COVID activity simultaneously for your state. The idea is that if your child is sick and RSV is very low but flu is high, the most useful thing the site can do is tell you that clearly — not just confirm RSV is quiet.

The season chart shows RSV hospital admissions week by week since October, colored by severity level, with a projection to season end. It lets you see at a glance whether RSV is climbing, peaked, or winding down — context a single number doesn't provide.

Symptom triage uses a three-tier structure — WATCH, CALL, 911 — to help parents recognize when RSV is progressing beyond normal cold symptoms. This section carries explicit disclaimers throughout. It is a general orientation to warning signs, not a clinical assessment of your specific child. If you're uncertain about your child's symptoms, call your pediatrician.

Home care covers what actually helps with RSV at home — saline, nasal suctioning, humidity, positioning, hydration monitoring — and what doesn't. It includes affiliate links to relevant products and tells you when to stop managing at home and seek care.

How the activity level is calculated

The core metric is weekly new RSV-associated hospitalizations by state and jurisdiction, sourced from the CDC HHS Protect surveillance system — the same underlying data used by public health officials. We map those counts to a 0–5 activity scale calibrated to state population baselines.

RSV hospital data captures the severe end of RSV burden — cases that required hospitalization — not total community spread or all doctor visits. Community spread is always higher than what hospital admissions data reflects. Think of the activity level as a signal that RSV is circulating and causing serious illness in your state, not a count of total infections.

Data updates weekly, typically Thursday or Friday, with a 1–2 week reporting lag from actual events. The site displays the most recently available data and notes this lag explicitly.

Data sources

RSV activity: CDC HHS Protect — weekly new RSV-associated hospitalizations by state, the authoritative US public health surveillance dataset for RSV severity. Flu and COVID data in the What's Going Around widget comes from parallel CDC surveillance systems, aggregated by a dedicated Cloudflare Worker. Immunization guidance references publicly available CDC and FDA recommendations.

State selection is stored in your browser's local storage and is never transmitted beyond what's needed to fetch your state's activity data.

The guides

Beyond the tracker, the site has 18 in-depth guides organized by audience — parents of infants, expectant families, adults 60+, and people with chronic conditions. They cover RSV symptoms, when to go to the ER, Beyfortus and Abrysvo, home care, how RSV spreads, RSV in pregnancy, the two adult vaccines compared, RSV with COPD and heart failure, and more. They're at isitrsvseasonyet.com/guides.

Every guide carries explicit "not medical advice" language and directs readers to their pediatrician or specialist for questions about their specific situation. The guides are designed to help parents understand the landscape — not to substitute for clinical judgment.

Who built this

This site is part of a small network of seasonal condition trackers built to answer the questions people actually ask when they're trying to figure out what's happening with their health. The flu counterpart is at isitfluseasonyet.com. Allergy tracking is at isitallergyseasonyet.com. The mosquito tracker is at isitmosquitoseasonyet.com.

Editorial decisions — what to show, how to frame it, which thresholds to use, what the triage language says — are made here, not by committee. If something seems wrong or out of date, the contact page goes directly to the person who built it.

What this site is not

This is not a medical resource. It does not provide individualized medical advice, diagnose conditions, or recommend specific treatments. The immunization timing information reflects publicly available CDC and FDA guidance as of 2026 — guidelines change, supply varies, and eligibility criteria evolve. Always confirm timing and eligibility with your pediatrician or OB before making immunization decisions.

The symptom triage section is designed to help parents recognize warning signs, not to replace clinical evaluation. No words on a screen can assess your specific child. When in doubt, call your pediatrician. If your child is struggling to breathe — don't read another article. Call 911.
