The Caribbean, Central and South America network for HIV epidemiology (CCASAnet) brings together the expertise and resources of Vanderbilt University and clinical and research sites in Argentina, Brazil, Chile, Haiti, Honduras, Mexico and Peru.

The goal of the CCASAnet project is to create a shared repository of HIV data from Central and South America and the Caribbean, and use the combined data to answer questions about the characteristics of the regional HIV epidemic. CCASAnet researchers will develop and test new biostatistical methods for HIV epidemiology and conduct a program of education to assist participating sites in improving the quality and consistency of their clinical research activities.

CCASAnet is a member of the International Epidemiologic Databases to Evaluate AIDS (IeDEA) consortium, a global network of researchers sponsored by the U.S. National Institute of Allergy and Infectious Diseases and the U.S. National Institutes of Health. The CCASAnet team collaborates with the members of other regional IEDEA networks in the development of international standards for sharing and analyzing HIV-related data.
