| # CDC FluSurv-NET — weekly flu hospitalisation rates |
|
|
| 14 RESP-NET catchments (some states host two — NY: Albany + Rochester) plus a `network_all` |
| aggregate. Seasonal — typically populated October through May. Pre-2018 the network was |
| smaller (FluSurv-NET predecessors operated different sites). |

| ## Coverage |
|
|
| - **Time:** 2003-10-04 → 2004-05-01; 2004-10-09 → 2005-04-30; 2005-10-08 → 2006-04-29; 2006-10-07 → 2007-04-28; 2007-10-06 → 2008-04-26; 2008-10-04 → 2009-05-02; 2009-09-05 → 2010-05-01; 2010-10-09 → 2011-04-30; 2011-10-08 → 2012-04-28; 2012-10-06 → 2013-04-27; 2013-10-05 → 2014-04-26; 2014-10-04 → 2015-05-02; 2015-10-10 → 2016-04-30; 2016-10-08 → 2017-04-29; 2017-10-07 → 2018-04-28; 2018-10-06 → 2019-04-27; 2019-10-05 → 2020-04-25; 2020-10-03 → 2021-05-01; 2021-10-09 → 2022-06-11; 2022-10-08 → 2023-04-29; 2023-10-07 → 2025-04-26; 2025-10-04 → 2026-01-03 |
| - **Cadence:** `weekly` (observed median spacing: 7 days) |
| - **Geography levels:** `subnational-region` — 14 unique location IDs |
| - **Countries:** US |

| | `rate_age_0` | per 100k population | `rate` | `rate` | Hospitalisation rate, age 0-4 | |

| | `rate_age_3` | per 100k population | `rate` | `rate` | Hospitalisation rate, age 50-64 | |
| | `rate_age_4` | per 100k population | `rate` | `rate` | Hospitalisation rate, age 65+ | |
|
|
| ### Additional data columns |
|
|
| - **`location_name`** — Source-native catchment code (e.g. `CA`, `NY_albany`, `network_all`). `location_id` prefixes with `US-FLUSURV-`. |
| |
| ## 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. |
| |
| - **`rate_overall`** — FluSurv-NET catchments are *not* whole-state populations. CA covers selected counties |
| in the SF Bay Area; NY has separate Albany and Rochester catchments. Don't compare |
| catchment rates to state-level flu rates from other sources without re-weighting. |
|
|
|
|
| ## Access |
|
|
| - **Availability:** `open` |
| - **Access type:** `delphi` |
| - **License:** other |
| - **Tier:** 2 |
