A global geographic database of human dengue virus occurrence. The database comprises occurrence data linked to point or polygon locations, derived from peer-reviewed literature and case reports as well as informal online sources. Entries date from 1960 to 2012.
OCCURRENCE_ID: Unique identifier for each occurrence in the database after temporal and locational standardisation.
SOURCE_TYPE: Manual entry vs. HealthMap
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 0 (national), 1 (state or province), 2 (district), and -999 when the location type is a point.
GAUL_AD0: The country-level global administrative unit layer (GAUL) code (see http://www.fao.org/geonetwork) which identifies the Admin-0 level occurrences as well as the Admin-0 polygon within which any smaller polygons and points lie.
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. Values of -999 are assigned when the polygon was Admin-0 level.
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-0 or Admin-1 level.
POINT_ID: The unique identifier which was assigned to points falling within the same 5km x 5km pixel.
UNIQUE_LOCATION: A unique identifier created for all locations (both points and polygons) based upon the point IDs 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.
COUNTRY: The name of the country within which the occurrence lies.
REGION: The region within which the occurrence lies – values are Asia, Oceania (includes Australia), Africa (includes the Arabian peninsula), and Americas.
