    description: >-
      Reported dengue cases in the period. May include suspected, probable, and
      laboratory-confirmed cases — see `case_status` (schema-standard) and
      `case_definition` (source-original) for the certainty tier of each row.
      Includes all severity levels (dengue, dengue with/without warning signs,
      severe dengue, dengue haemorrhagic fever, dengue shock syndrome, dengue
      deaths) where reported.
    aggregation: sum
notes:
  extra_columns:
    - column: case_definition
      description: >-
        Source-original case definition: `Suspected`, `Probable`, `Confirmed`,
        `Probable and confirmed`, `Suspected and confirmed`, `Total`. Preserved
        alongside the schema-standard `case_status` so original fidelity isn't
        lost. The same (country, date) cell can have multiple rows when the
        source distinguishes definitions — filter to one for a single time
        series.
    - column: temporal_resolution
      description: >-
        Per-row temporal granularity (`Week` or `Month`). Coarser source
        aggregates (`Year`, `Total`) are filtered out at ingest — the dashboard
        can sum kept rows on the fly when an annual roll-up is needed.
    - column: location_name
      description: >-
        Source's English country name (uppercase). `location_id` (ISO 3166-1
        alpha-2) is canonical.
  interpretation_caveats:
    - column: case_status
      caveat: >-
        Mapping from the source's `case_definition`: `Probable and confirmed` →
        `probable` (looser tier of the union, the minimum certainty
        represented); `Suspected and confirmed` → `suspect`; `Total` →
        `not-classified`. The original definition is preserved in
        `case_definition` for full fidelity.
    - column: dengue_total
      caveat: >-
        Cross-country comparability is limited — case definitions, reporting
        completeness, and surveillance intensity vary substantially. OpenDengue
        normalizes structure but does not normalize underlying definitions. For
        modeling, prefer one country at a time or one case_status consistently.
    - column: case_definition
      caveat: >-
        `Probable and confirmed` and `Suspected and confirmed` are *summed*
        categories from sources that combine tiers — they are not standalone
        classifications. Don't sum them with `Confirmed`/`Probable`/`Suspected`
        rows from the same country and date.
    - column: temporal_resolution
      caveat: >-
        A country may switch between Week and Month over its history. Pick one
        resolution per country when constructing a continuous series; don't
        naively concatenate rows of different temporal_resolution.
  general: >
    OpenDengue (Clarke et al. 2024, https://doi.org/10.1038/s41597-024-03120-7)
    is a

    standardized archive of dengue case reports from public national
    surveillance

    systems. This dataset is the V1.3 **national** extract; subnational extracts

    (`Spatial_extract`, `Temporal_extract`) are larger and could be ingested as

    sibling datasets later (`opendengue-admin1`, `opendengue-admin2`).


    Coverage spans 1993-present (with a small 1924-1925 fragment), but

    per-country availability varies widely — Brazil has weekly data 2014+,

    others only monthly. Annual and Total aggregates from the source are

    filtered out so the dataset is series-shaped; sum kept rows in the

    dashboard when an annual roll-up is needed. Use the `case_status` /

    `case_definition` and `temporal_resolution` row-level columns to

    construct a coherent series.

OpenDengue — national dengue case counts (V1.3)

OpenDengue (Clarke et al. 2024, https://doi.org/10.1038/s41597-024-03120-7) is a standardized archive of dengue case reports from public national surveillance systems. This dataset is the V1.3 national extract; subnational extracts (Spatial_extract, Temporal_extract) are larger and could be ingested as sibling datasets later (opendengue-admin1, opendengue-admin2).

Coverage spans 1993-present (with a small 1924-1925 fragment), but per-country availability varies widely — Brazil has weekly data 2014+, others only monthly. Annual and Total aggregates from the source are filtered out so the dataset is series-shaped; sum kept rows in the dashboard when an annual roll-up is needed. Use the case_status / case_definition and temporal_resolution row-level columns to construct a coherent series.

Columns

Column	Unit	value_type	Aggregation	Description
`dengue_total`	cases	`incident`	`sum`	Reported dengue cases in the period. May include suspected, probable, and laboratory-confirmed cases — see `case_status` (schema-standard) and `case_definition` (source-original) for the certainty tier of each row. Includes all severity levels (dengue, dengue with/without warning signs, severe dengue, dengue haemorrhagic fever, dengue shock syndrome, dengue deaths) where reported.

Additional data columns

case_definition — Source-original case definition: Suspected, Probable, Confirmed, Probable and confirmed, Suspected and confirmed, Total. Preserved alongside the schema-standard case_status so original fidelity isn't lost. The same (country, date) cell can have multiple rows when the source distinguishes definitions — filter to one for a single time series.
temporal_resolution — Per-row temporal granularity (Week or Month). Coarser source aggregates (Year, Total) are filtered out at ingest — the dashboard can sum kept rows on the fly when an annual roll-up is needed.
location_name — Source's English country name (uppercase). location_id (ISO 3166-1 alpha-2) 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.

case_status — Mapping from the source's case_definition: Probable and confirmed → probable (looser tier of the union, the minimum certainty represented); Suspected and confirmed → suspect; Total → not-classified. The original definition is preserved in case_definition for full fidelity.
dengue_total — Cross-country comparability is limited — case definitions, reporting completeness, and surveillance intensity vary substantially. OpenDengue normalizes structure but does not normalize underlying definitions. For modeling, prefer one country at a time or one case_status consistently.
case_definition — Probable and confirmed and Suspected and confirmed are summed categories from sources that combine tiers — they are not standalone classifications. Don't sum them with Confirmed/Probable/Suspected rows from the same country and date.
temporal_resolution — A country may switch between Week and Month over its history. Pick one resolution per country when constructing a continuous series; don't naively concatenate rows of different temporal_resolution.
