OpenDengue: data from the OpenDengue database

The OpenDengue project aims to build and maintain a database of dengue case counts for every dengue-affected country worldwide since 1990 or earlier. We collate data from a range of publicly available sources including ministry of health websites, peer-reviewed publications and other disease databases.

The complete details, methodologies, and findings associated with this dataset are available in our research paper (https://doi.org/10.1038/s41597-024-03120-7).

The latest database is available on our OpenDengue website (https://opendengue.org/data.html). Past and current versions are also available in the Opendengue Github repository (https://github.com/OpenDengue/master-repo).

File descriptor

1. Global summaries of data: We provide three global summaries of the data in OpenDengue. We provide the best national estimate (National_extract.csv), the best temporal resolution (Temporal_extract.csv) and the best spatial resolution (Spatial_extract.csv). This allows users to customise their data extraction based on their research question. Each row in the data table contains a unique, non-overlapping location and time period with the associated dengue case data. The below codebook describes each variable.

• adm_0_name : administrative level 0/country name
• adm_1_name : administrative level 1 name
• adm_2_name : administrative level 2 name
• full_name : full place name
• ISO_A0 : ISO country code
• FAO_GAUL_code : Food and Agricultural Organization Global Administrative Unit Layer Code
• RNE_iso_code : RNaturalEarth ISO code
• IBGE_code : Brazilian Instituto Brasileiro de Geografia e Estatística (IBGE) code
• calendar_start_date : the start date in calendar time with the format YYYY-mm-dd
• calendar_end_date : the end date in calendar time with the format YYYY-mm-dd
• Year : year
• dengue_total : the total dengue case count relating to the period and place (see dengue classification protocol and dengue double count protocol)
• case_definition_standardised : case definition after standardisation
• S_res : spatial resolution
• T_res : temporal resolution
• UUID : Universal Unique Identifier relating to the source file from which the data originates
