+# PHAC Respiratory Virus Detection Surveillance — Canada weekly
+
+PHAC publishes a single weekly CSV. Long-format with one row per
+(date × jurisdiction × virus). The dataset replaces FluWatch+ as Canada's
+multi-virus respiratory surveillance feed. Note that some "regions" are PHAC
+rollups (Atlantic, Prairies) sitting alongside individual provinces.

+
+## Coverage
+
+- **Time:** 2025-08-30 → 2026-04-18
+- **Cadence:** `weekly` (observed median spacing: 7 days)
+- **Geography levels:** `national`, `subnational-state`, `subnational-region` — 17 unique location IDs
+- **Countries:** CA
+- **Pathogens:** `influenza`, `influenza-a`, `influenza-b`, `sars-cov-2`, `rsv`, `hmpv`, `adenovirus`, `parainfluenza`, `rhinovirus-enterovirus`, `seasonal-coronavirus`
+- **Surveillance category:** `respiratory`
+- **Rows:** 2,720
+
+## Columns
+
+| Column | Unit | value_type | Aggregation | Description |
+|--------|------|------------|-------------|-------------|
+| `tests` | specimens/week | `incident` | `sum` | Number of specimens tested for this virus, this region, this week |
+| `detections` | positives/week | `incident` | `sum` | Number of specimens that detected this virus |
+| `percentpositive` | percent (0-100) | `proportion` | `rate` | Share of specimens positive (`detections / tests`) |
+
+### Additional data columns
+
+- **`condition_native`** — PHAC virus name (`SARS-CoV-2`, `Influenza A`, `RSV`, ...). `condition` is the EPI-Eval slug.
+- **`location_name`** — Province / territory / region name from PHAC. `location_id` 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.
+
+- **`condition`** — Includes 'adenovirus', 'parainfluenza', 'rhinovirus-enterovirus', 'seasonal-coronavirus' which are *not yet in vocabularies.yaml*. Adding them is recommended (low-cost extension).
+- **`percentpositive`** — PHAC reports % to 1 decimal; small jurisdictions can swing widely week-to-week.
+
+## Access
