Each of the 1,720 rows represents a single occurrence record (one or more CCHF cases in the same unique location within a single calendar year). The fields contained in the database are as follows:

OCCURRENCE_ID: Unique identifier for each occurrence in the database after temporal and locational standardisation.LOCATION_TYPE: Whether the record represents a point or a polygon location.ADMIN_LEVEL: The administrative level which the record represents when the location type is a polygon. Values are 1 (state or province), 2 (district) and -999 when the location type is a point.GAUL_AD1: The first-level GAUL code which identifies the Admin-1 level occurrences as well as the Admin-1 polygon within which any smaller polygons and points lie.GAUL_AD2: The second-level GAUL code which identifies the Admin-2 level occurrences as well as the Admin-2 polygon within which any points lie. Values of -999 are assigned when the polygon was Admin-1 level.UNIQUE_LOCATION: A unique identifier created for all locations (both points and polygons) based upon the unique point locations (in same 5km x 5km pixels) and the GAUL codes.X: The longitudinal coordinate of the point or polygon centroid (WGS1984 Datum).Y: The latitudinal coordinate of the point or polygon centroid (WGS1984 Datum).YEAR: The year of the occurrence.

10. COUNTRY: The name of the country within which the occurrence lies.

11. REGION: The region within which the occurrence lies – values are Asia, Europe, and Africa (includes the Arabian peninsula).

In addition to the main comma-delimited file, three supplementary files are included as part of the file set which can be found online (Data Citation 1). These include two text documents: (i) a bibliography of the published literature used for inputting occurrence records, and (ii) a list of accession ID numbers for those records obtained from GenBank. The third supplementary file is an additional comma-delimited file containing the HealthMap records entered into the database( before standardization and technical validation). This database contains information on the year of each report, as well as the latitude and longitude of the disease occurrence and the source from which this information was extracted.
