From The NIH National Heart, Lung and Blood Institute:
In the 1980s, infection with HIV, the virus that causes AIDS, was often viewed as a death sentence. With no treatments available and little understanding of the virus or the disease, hundreds of thousands of people in the United States ultimately lost their lives and millions more died worldwide.
Much has changed in the past four decades. Thanks to the availability of powerful antiretroviral drugs, new infections have decreased significantly, the virus is held at low levels in the body, and the HIV death rate has plummeted. People living with HIV are now more likely to die of a chronic illness, such as cardiovascular disease, than from AIDS. Meanwhile, researchers continue to make inroads in finding an effective vaccine or even a cure.
Now, this year, another milestone: the nation’s largest and longest running study of HIV survivors is marking its 40th anniversary.
The Multicenter AIDS Cohort Study (MACS) launched in 1984 to help shed light on how AIDS was affecting gay and bisexual men living with or at risk for HIV. Over the years it enrolled some 7,300 men and eventually merged with the Women’s Interagency HIV Study (WIHS). That study has focused on the health impact of HIV on nearly 5,000 women living with or at risk for the virus.
