# CDC NREVSS — weekly RSV test specimens and positives

NREVSS is the long-running multi-pathogen lab network. The full system covers flu,
RSV, parainfluenza, hMPV, adenovirus, etc.; this Socrata view exposes only the
RSV portion. Other pathogens are in sibling Socrata datasets (separate ingests).

**Source:** <https://www.cdc.gov/nrevss/php/dashboard/index.html>

## Coverage

- **Time:** 2010-07-10 → 2020-06-27
- **Cadence:** `weekly` (observed median spacing: 7 days)
- **Geography levels:** `subnational-region` — 10 unique location IDs
- **Countries:** US
- **Pathogens:** `rsv`
- **Surveillance category:** `respiratory`
- **Rows:** 10,313

## Columns

| Column | Unit | value_type | Aggregation | Description |
|--------|------|------------|-------------|-------------|
| `rsvpos` | specimens/week | `incident` | `sum` | Specimens testing positive for RSV (this test type, this region, this week) |
| `rsvtest` | specimens/week | `incident` | `sum` | Total specimens tested for RSV |

### Additional data columns

- **`testtype`** — `Antigen` or `PCR`. Always 2 rows per (date, region) — one per test type. Treat as a row-level dimension; downstream % positive is computed per testtype.
- **`outlier`** — 1 = source itself flagged this point as an outlier (excluded from CDC's published trend).
- **`location_name`** — `HHS N` for traceability. `location_id` (`US-HHS-N`) is canonical.

## Interpretation caveats

Things that may differ from how other sources define a similar measure. If you're combining this dataset with another, read these first.

- **`rsvtest`** — PCR vs antigen counts are NOT comparable. PCR ramped up post-2018; antigen has been the long-term backbone but is less sensitive. Don't sum across testtype — they're parallel signals.

## Access

- **Availability:** `open`
- **Access type:** `socrata`
- **License:** other
- **Tier:** 2
