Unitaid is a global health initiative that works with partners to bring about innovations to prevent, diagnose and treat major diseases in low- and middle-income countries, with an emphasis on tuberculosis, malaria, and HIV/AIDS and its deadly co-infections. Founded in 2006, the organization funds the final stages of research and development of new drugs, diagnostics and disease-prevention tools, helps produce data supporting guidelines for their use, and works to allow more affordable generic medicines to enter the marketplace in low- and middle-income countries. Hosted by the World Health Organization (WHO) in Geneva, Unitaid was established by the governments of Brazil, Chile, France, Norway and the United Kingdom.
