It’s been 34 years since the first AIDS cases were diagnosed—epidemiologically speaking, that’s the blink of an eye. And yet it can still feel like we’re making little headway against HIV.
But we’re making great strides—in record time. Below, we count eight signs that we’re moving closer to an HIV-free world.

Studies have shown that a gay 20-year-old man who is HIV positive can expect to live to 77, the same for a 20-year American man who is HIV-negative.
Of course, that outcome is not guaranteed—especially if you’re from a different race or socioeconomic background.
We’re closer than ever to an HIV vaccine.
A new vaccine spearheaded by Robert Gallo, one of the earliest AIDS researchers, is ready for human trials.
It’s designed to bind to the virus at the moment of infection, making it more effective than previous attempts at a vaccine.
Scientists can now remove HIV from human cells.
Last year researchers at Temple University were able to destroy HIV in human cells, rather than simply suppress it.
“It’s an important finding because, for the first time in laboratory setting, we show that the virus can be eradicated from human culture, cell culture,” said Dr. Kamel Khalili, who led the research team at Temple’s Center for Neurovirology.
Introduced just three years ago, pre-exposure prophylaxis has become an increasingly popular treatment for helping HIV-negative people stay that way.
The CDC and World Health Organization have both broadened the guidelines for who should be taking PrEP—and insurance carriers are starting to cover it, as well.
Infection rates in San Francisco are plummeting.
San Francisco was home to some 2,300 new HIV diagnoses in 1992. This year, that number was about 300.
That’s thanks to a massive citywide campaign to eradicate the virus through a variety of initiatives, including providing PrEP free of charge to those in need, and prescribing antiretroviral drugs as soon as someone tests positive.
“If [San Francisco] keeps doing what it is doing, I have a strong feeling that they will be successful at ending the epidemic as we know it,” said Dr. Anthony S. Fauci, director at the National Institute of Allergy and Infectious Diseases.
15 million people worldwide are receiving HIV treatment.
UNAIDS announced the goal to provide treatment for 15 million people with HIV has been met—ahead of schedule!
“We are on the way to a generation free of AIDS,” declared U.N. Secretary-General Ban Ki-moon. “Now we must commit to ending the AIDS epidemic.”
A gene has been discovered that “turns off” HIV.
Actually, researchers have found TWO genes that disable the virus. SERINC5 and SERINC3 block HIV’s ability to infect new cells.
Normally they’re deactivated by the HIV-1 Nef protein, but new drugs could target Nef and allow SERINC to “turn off” the virus.
Pot might help fight HIV.
Marijuana has long been used to treat the nausea and discomfort associated with HIV and its treatments, but research suggests pot might help stop the spread of the virus itself.
A 2014 study out of Louisiana State University found that HIV-positive monkeys given daily doses of THC (the active ingredient in cannabis) had less deterioration in the immune tissue in the stomachs.
And research from 2012 points to evidence that marijuana compounds can fight HIV in late-stage AIDS patients.
But the news is not all good: While HIV infection rates are down in general in the U.S., they’re spiking for men who have sex with men.
A report in the Journal of the American Medical Association found that HIV diagnosis rates among gay and bi men aged 13-24 rose from about 3,000 to about 7,000 between 2002 and 2011.
Experts point to poor risk-assesment skills, and a generation that wasn’t alive during the worst of America’s AIDS epidemic, as factors. Until there is a cure, it’s our responsibility to educate ourselves and each other into making safer and smarter choices.
