# JHU CSSE COVID-19 — global daily (archived)

JHU stopped active maintenance 2023-03-09 and archived the repo. Province-level rolls
are present in the source files but dropped here (province names are free-text, not
ISO 3166-2; a per-country crosswalk is needed and is out of scope for this v0.1 ingest).

**Source:** <https://github.com/CSSEGISandData/COVID-19>

## Coverage

- **Time:** 2020-01-22 → 2023-03-09
- **Cadence:** `daily` (observed median spacing: 1 days)
- **Geography levels:** `national` — 194 unique location IDs
- **Countries:** multiple
- **Pathogens:** `sars-cov-2`
- **Surveillance category:** `respiratory`
- **Rows:** 225,171

## Columns

| Column | Unit | value_type | Aggregation | Description |
|--------|------|------------|-------------|-------------|
| `confirmed` | cases (cumulative) | `cumulative` | `max` | Cumulative confirmed COVID-19 cases reported to JHU CSSE |
| `deaths` | deaths (cumulative) | `cumulative` | `max` | Cumulative confirmed COVID-19 deaths |
| `recovered` | people (cumulative) | `cumulative` | `max` | Cumulative recoveries; many jurisdictions stopped reporting this in 2021, so column is mostly NaN late in the series |

### Additional data columns

- **`location_name`** — JHU's English country name. `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.

- **`recovered`** — Most countries stopped reporting recoveries by 2021-Q3; this column is functionally dead post-2021. Don't use as a target.
- **`confirmed`** — JHU compiled from ad-hoc national sources; definitions, lab criteria, and reporting cadence vary
wildly between countries and over time. Treat as a global-shape signal, not a comparable rate.

## Access

- **Availability:** `inactive`
- **Access type:** `github`
- **License:** cc-by-4.0
- **Tier:** 3
