IAPAC’s 25-Year History

The Physicians Association for AIDS Care (PAAC) was the first organization to support US physicians in the mid-1980s as they ministered to people who, given limited treatment options, were quickly dying of AIDS-related complications. PAAC was the precursor to the International Association of Physicians in AIDS Care (IAPAC), which was incorporated on 7 February 1995 to represent HIV-treating physicians and allied healthcare professionals worldwide. Today, IAPAC is known as the International Association of Providers of AIDS Care — a name change that took place on 1 December 2012 as formal acknowledgement of the contributions made by various cadres of professional and paraprofessional providers of HIV prevention, care, and treatment services.

Throughout its five-year history, PAAC delivered pre-ART era education about nutrition, pain management, opportunistic infections (OIs), and other complications of HIV disease. It also tackled contentious public policy issues. Most notably, PAAC publicly confronted the American Medical Association (AMA) and the American Dental Association (ADA) in 1991 over proposed sanctions against HIV-infected healthcare workers following reports that an HIV-positive Florida dentist had likely transmitted HIV to three of his patients. The US Centers for Disease Control (CDC) ultimately resolved the dispute by issuing less restrictive guidelines.

From this important beginning, PAAC’s successor association, IAPAC, has worked over the past 17 years to marshal the coordinated strength of healthcare professionals worldwide to the benefit of people living with and affected by HIV/AIDS. Because its rebirth coincided with the advent of antiretroviral therapy (ART), IAPAC engaged in education activities worldwide to strengthen the health workforce’s capacity to deliver HIV care, treatment, and support. And, its advocacy efforts to scale-up access to ART in developing world countries began in the late 1990s - well before even the United Nations called for breaking down access barriers and facilitating universal access to ART.

IAPAC today represents more than 17,000 clinicians and other healthcare professionals in over 100 countries who deliver both prevention and treatment services in multiple disease areas, including HIV, hepatitis, malaria, and tuberculosis. Its educational, research, technical assistance, and advocacy activities are conducted by a professionally diverse staff, and are guided by an international Board of Trustees composed of highly esteemed medical, public health, and advocacy professionals from across five continents.

IAPAC is recognized under the law of the United States of America as a 501(c)(3) not-for-profit organization. Working in partnership with the healthcare professions, business, government, academe, and religious communities, IAPAC accomplishes its mission through a comprehensive program of education, policy and advocacy, direct technical assistance, research, and care provision initiatives spearheaded by its members.

IAPAC’s strength is firmly rooted in the belief that the most effective and creative solutions to ongoing issues of access to and provision of HIV prevention, care, and treatment services evolve from within the association’s membership. IAPAC provides educational services to its membership on best clinical practices in managing HIV and its associated complications, while it also develops and implements innovative public healthcare policies that reflect its membership’s commitment to changing the course of the HIV pandemic.
