IeDEA Regional Cohorts

IeDEA is an international research consortium established in 2006 by the US National Institutes of Health to provide a rich resource for globally diverse HIV data.
The International epidemiology Databases to Evaluate AIDS (IeDEA) collects observational data representing over 2.2 million people living with and at risk for HIV, contributed by clinical centers and research groups in 44 countries. IeDEA data are organized into 7 geographic regions and coordinated by centers for the Asia-Pacific, the Caribbean, Central and South America region, Central, East, Southern, and West Africa, and North America.
