Accessing data

WWARN promotes data sharing and data re-use to generate new evidence that improves health and understanding of malaria. Researchers can request access to malaria data held in IDDO’s data repository. The Malaria Data Inventory shows the list of data that is currently available. View a visual summary of the IDDO Data Access Journey.

The Data Inventory enables you to search and request access to data sets by searching through PubMed ID, or to review the full list of data sets available to see publication title, publication year, and WWARN identifier.      

How to request data

Submit the form to

The WWARN Malaria Data Dictionary

Download the Data Dictionary – the file will be updated, please download the latest version when you start your analysis.

Please note these important considerations when reviewing the WWARN Data Dictionary:

  • Not every study contributed to WWARN collected all the variables listed in the Data Dictionary

  • In a publication, Data Contributors may have reported collecting data listed in the Data Dictionary, but may not have shared those variables with WWARN

  • Occasionally some studies contain data listed in the Data Dictionary that will require curation before release. The vast majority of data is already fully curated and this only happens for very old data sets or data that may have been shared incrementally. We will let you know after receiving your request if the data requires curation and the time this is expected to take.

Once a Data Access request has been submitted

The IDDO Data Access Committee (DAC) manages and oversees all data access applications for re-use of malaria data, in accordance with the Data Access Guidelines and the Data Use Agreement. The DAC aims to review applications and respond to requests within two months of submission. The Data Access Guidelines detail our principles of data access, who can request data and how the DAC operates.

The technical, governance and ethical framework for our data access strategy has been developed to promote access to data for research, while protecting the rights and privacy of the people and communities from which the data originate, and respecting the investment of the researchers who conducted the studies and collected the data.
