Emergency department visit share by county (NSSP)
CDC National Syndromic Surveillance Program
In a RepVector build, this dataset quantifies clinical need and utilisation across the population.

What this dataset is
Weekly percentage of emergency department visits attributed to COVID-19, influenza and RSV for each county, with rising/falling trend classifications. A near-real-time read on acute care demand and respiratory illness pressure in a place. It is published by CDC National Syndromic Surveillance Program and can be queried at county level, refreshed weekly. Each row is a period observation, so results show direction and rate of change rather than a single snapshot.
Why it is useful
- Separates markets with real clinical demand from markets that only have supply.
- Grounds a territory case in published prevalence and utilisation instead of assumption.
- Highlights where need outruns available capacity — usually the fastest conversations.
Questions it helps answer
- Where is the underlying clinical need highest relative to available capacity?
- How does utilisation here compare with the state and national picture?
- Which measures are suppressed or unreported for this geography?
How different verticals use it
RepVector is vertical-agnostic: this dataset is selected by what your question asks for, not by industry. These are common ways teams put it to work.
Prioritises territories where clinical need outruns available capacity.
Quantifies prevalence and utilisation behind a programme or referral case.
Informs risk and benefit design with published utilisation patterns.
Shows community health pressures that shape support-service demand.
How RepVector uses it
- You describe a market in plain language. The geography resolver turns the place you named into the exact identifiers this dataset needs — city to county to state, plus DMA where relevant — so a query at county runs without you knowing any codes.
- The planner selects Emergency department visit share by county (NSSP) only when your question matches what it actually reports. It is never included to pad a result.
- Returned rows are normalised into the shared metric layer, so figures from CDC National Syndromic Surveillance Program line up with every other source in the same dashboard instead of sitting in an isolated table.
- Quality checks score coverage and recency. If CDC National Syndromic Surveillance Program suppresses or omits a value for your geography, the gap is reported as a gap — nothing is estimated or filled in.
- The result renders as charts, KPIs and, where the rows are entities, prioritised targets you can export to PDF, Excel, CSV or JSON.
What it does not tell you
- Aggregated and often suppressed at small geographies to protect privacy; gaps are reported rather than filled in.

How it fits with the rest of the catalog
Need data explains why a territory matters; provider and facility data explains who you visit once you get there. RepVector queries every selected dataset against the same resolved geography and time window, then normalises the results into one metric layer so they can be charted side by side. These datasets are the most common companions to Emergency department visit share by county (NSSP):

Common questions
What does Emergency department visit share by county (NSSP) contain?
Weekly percentage of emergency department visits attributed to COVID-19, influenza and RSV for each county, with rising/falling trend classifications. A near-real-time read on acute care demand and respiratory illness pressure in a place. It is published by CDC National Syndromic Surveillance Program at county grain.
How often is it refreshed?
CDC National Syndromic Surveillance Program publishes on a weekly cycle. RepVector re-reads the source on that cadence and keeps every prior capture, so you can see what changed.
Do I need an account to use it?
No. Browsing the catalog and the free lookup tools needs no account. Running a full market build across every county in a territory is the paid product.
