International HIV/STD Section
Established in 1984
Thomas C. Quinn, M.D., M.Sc. (He/Him/His)
Chief, International HIV/STD Section
Specialty(s): Infectious Disease, Internal Medicine
Major Areas of Research
- Definition of epidemiologic features of HIV-1 and HIV-2 infections in developing countries and the United States
- Assessment of biomedical interventions to control HIV, including circumcision, prevention of mother-to-child transmission, pre-exposure prophylaxis, and vaccine development
- Study of the serologic responses to SARS-CoV-2 and other coronaviruses to aid in the defining the epidemiologic features and clinical responses to COVID-19 in US and Africa
- Quantification of the latent HIV reservoir in virally suppressed Ugandan men and women with identification of immunologic predictors of the reservoir size
HIV/AIDS is a global pandemic with 37 million individuals living with HIV infection worldwide. Approximately 2.1 million people become infected each year, and over 39 million people have already died as a result of HIV-related diseases. Although an estimated one million people are HIV infected in the U.S., the vast majority of HIV-infected individuals reside in developing countries. HIV infection continues to spread rapidly among heterosexuals and perinatally throughout Africa, Latin America, and Asia. Since the beginning of this project, the International HIV/STD Laboratory of the LIR has instituted international collaborations in 28 countries. The objectives of this lab are: 1) To define the unique epidemiologic, clinical, virologic, and immunologic features of HIV-1 infection and co-infections in developing countries; 2) To examine the viral kinetics and other biological and behavioral factors associated with HIV-1 transmission; 3) To characterize the molecular strains of HIV-1 by region for infectiousness, transmission, and immunologic response including the role of HIV superinfection; 4) To develop and evaluate novel interventions to prevent HIV transmission, including microbicides, circumcision and vaccines; 5) To examine the efficacy of antiretroviral drugs in preventing transmission and increasing survival in developing countries; 6) To examine the effects of HIV+ to HIV+ solid organ transplantation of patient health, HIV disease, and immunological make-up.

M.Sc., 1970, University of Notre Dame, IN
M.D., 1974, Northwestern University, Evanston, IL
Dr. Quinn obtained his M.D. from Northwestern University. He was a research associate in infectious diseases in the NIAID Laboratory of Parasitic Diseases and completed a fellowship in infectious diseases at the University of Washington. He returned to NIAID and later became chief of the Section on International HIV/STI Research. In 2006, he was appointed as associate director for International Research in the Division of Intramural Research. Since 1981, he has been assigned to the division of infectious diseases at Johns Hopkins University, where he became a professor of medicine in 1991, and in 2006 became director of the Center for Global Health. Dr. Quinn is a member of the National Academy of Medicine in the National Academies of Science and is a fellow of the American Association for the Advancement of Science and the Association of American Physicians.
