| Hospital reporting became voluntary 2024-05-01 to 2024-11-09; mandatory reporting resumed | |

| ### Additional data columns | |
| - **`location_name`** — 2-letter postal abbreviation as reported by the source. Kept for traceability; `location_id` is canonical. | |
| - **`respseason`** — Respiratory season identifier (e.g. '2024-2025'). NHSN-specific; useful for grouping by season but doesn't appear in other sources. | |
| ## 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. | |
| - **`numinptbeds`** — Counts only *staffed* beds (those with available staff to operate). HHS Protect's analogous capacity column had different inclusion criteria; do not naively splice across the 2024-11 boundary. | |
| - **`totalconfflunewadm`** — Counts new admissions where flu was confirmed by lab on or within 14 days of admission. Reporting jurisdictions varied this rule pre-2024-11; treat pre-2024-11 values as approximate. | |
| - **`totalconfrsvnewadm`** — RSV mandatory reporting started epiweek 2024-46; pre-2024-46 values are NaN or sparsely populated by voluntary reporters. | |
| - **`*cumulativeseasonalsum`** — Cumulative within a respiratory season (resets at season boundary). Use with `value_type: cumulative` discipline — never sum, diff to recover incident. | |
