US influenza-like illness intensity, weekly by state
Weekly influenza-like illness intensity for 50 US states + DC from CDC ILINet (via the keyless CMU Delphi Epidata API), 2015-16 season to the latest released week (~26k (week, state) rows per snapshot). Per row: ili_pct (% outpatient visits for ILI), provider/patient coverage, per-state seasonal baseline (same week, prior 3 years; trailing-2y fallback), ili_zscore, week-over-week change (pp), 4-week trend slope, activity_band (minimal/low/moderate/high/very_high), elevated_flag, and flu_intensity_score (0-100 = min(100, round(50*clip(z/4)+30*clip(ili/8)+20*clip(wow/3)))). Units: %, pp, z, 0/1 flags, 0-100 score. Caveats: syndromic surveillance, not lab-confirmed flu — captures other respiratory pathogens; CDC revises recent weeks, so re-runs can legitimately supersede values.

| Colonne | Type | Description |
|---|---|---|
| state_code | string | Two-letter US postal code (50 states + DC) — join key. |
| state_name | string | State/district name. |
| region_type | string | 'state' or 'district' (DC). |
| country_code | string | ISO alpha-3 country code: USA. |
| epiweek | integer | CDC MMWR epiweek as YYYYWW (week 1 contains Jan 4). |
| week_ending | date | Saturday ending date of the epiweek (ISO date) — join key. (unit: date) |
| season | string | Flu-season label; seasons start at week 40 (e.g. '2025-26'). |
| ili_pct | float | Weighted % of outpatient visits for influenza-like illness (fever + cough/sore throat) reported to ILINet (Delphi 'wili'; falls back to 'ili'). (unit: %) |
| num_providers | integer | ILINet outpatient providers reporting that week (coverage); honest null for the latest provisional weeks — Delphi backfills provider counts with a lag. |
| num_patients | integer | Total patients seen by reporting providers that week; honest null when Delphi omits it. |
| baseline_mean | float | Per-state seasonal baseline mean %ILI: same week number in the prior 3 years (>= 2 present), else trailing-104w mean (>= 52 present). (unit: %) |
| baseline_sd | float | Standard deviation of the baseline window. (unit: %) |
| baseline_method | string | 'seasonal_3y', 'trailing_2y', or 'absolute_fallback' (no baseline; z-score null). |
| ili_zscore | float | (ili_pct - baseline_mean) / max(baseline_sd, 0.05); the 0.05 floor damps off-season micro-fluctuations. (unit: z) |
| ili_wow_change_pp | float | Week-over-week change in ili_pct, percentage points. (unit: pp) |
| trend_4w_slope | float | Least-squares slope of ili_pct over the trailing 4 weeks. (unit: pp/week) |
| activity_band | string | minimal/low/moderate/high/very_high. minimal when ili_pct < 1.0 or z < 1.0; else z-bands [1,2)/[2,3)/[3,4)/>=4; absolute %ILI scale (<1/<2/<3.5/<5) when no z-score exists. |
| flu_intensity_score | integer | 0-100: min(100, round(50*clip(z/4,0,1) + 30*clip(ili_pct/8,0,1) + 20*clip(wow_pp/3,0,1))). Higher = more intense flu-season pressure that week. |
| elevated_flag | integer | 1 when activity_band is moderate, high, or very_high. |
| source | string | Upstream provider key: 'delphi_epidata'. |
| source_url | string | Delphi Epidata FluView API documentation URL. |
| row_hash | string | Deterministic row identifier: 16-hex sha256 of 'cdc_ili|<state>|<epiweek>|<ili_pct>|<providers>'. |
