On June 5, 1981, the Centers for Disease Control and Prevention reported the first cases of a mysterious disease afflicting young, otherwise healthy men in a tiny suburb of Los Angeles, California. The disease, now known as AIDS, would go on to infect 85.6 million people around the world, sparking an epidemic that persists to this day.
On February 6, 2024, Duke’s Global Health Institute hosted a conversation with Dr. James Curran and Dr. Kevin M. De Cock, both former leaders at the CDC, about their experiences on the frontlines of the AIDS crisis in the earliest days of this epidemic. The conversation was moderated by Dr. Chris Beyrer and Dr. Nwora Lance Okeke, two Duke researchers in infectious disease.

The Origin of the Epidemic
The first cases of AIDS were reported by Dr. Michael Gottlieb, a young immunologist from UCLA. His groundbreaking findings, published in the CDC’s Morbidity and Mortality Weekly Report, described “previously healthy gay men from Los Angeles, San Francisco, and New York, who presented with rare opportunistic infections,” said De Cock. These infections, known as PCP (Pneumocystis carinii pneumonia) and KS (Kaposi’s sarcoma), were extremely rare. Upon observation, Gottlieb identified a startling commonality among the cases: they were all sexually active gay men.
These findings “didn’t fit into any organizational unit at the CDC,” so a multispecialty task force was formed. Led by Curran, it recruited experts in STIs, parasitology, virology, cancer, and more.
Tracking the Epidemic
At the start of the epidemic, cases were phoned into the CDC by individual doctors. But this quickly became inadequate. The epidemic was growing fast, and CDC phone lines could not keep up. “The CDC, therefore, developed a surveillance case definition for the syndrome,” De Cock explained. “Cases meeting this definition were reported through health departments to the CDC.”
“I think we were able with the case definition for surveillance, to take advantage of the fact that all of these conditions were very serious and so unusual that the physician would say ‘I’ve never seen anything like it,’…,” Curran said. “The other conditions were far less specific and far less useful for tracking the disease.”
In October 1981, these tracking protocols helped identify AIDS as a sexually transmitted disease. A national case-control study found that sexual activity was a leading risk factor, and a cluster of cases in 10 US cities linked via sexual contact was discovered. “People just didn’t want to believe it,” Curran said. “They wanted to believe that it wasn’t something transmissible.”
Expanding Epidemic
Over the next year, the epidemic expanded to include injection drug users, heterosexual partners of bisexual men, people of Haitian descent, and infants. But perhaps most surprising was the transmission occurring through blood transfusion. In December 1982, a case of AIDS-like illness was reported in a 20-month-old infant after receiving blood from a donor who later developed the virus.
“Until that December report of the infant, the mainstream media had actually paid very little attention to AIDS. But that suddenly changed,” said De Cock. “While AIDS was seen as a problem of marginalized groups… it was easy to ignore. But anyone might need a blood transfusion.”
In the following years, rumors surrounding transmission and contact sparked nationwide panic. Fear of contracting the disease caused AIDS patients to lose their jobs and housing. Although the CDC provided up-to-date information on the nature of the virus, quelling public fear was extremely difficult. “AIDS proved that you can’t separate prevention and treatment,” Curran explained.
Modern AIDS Era
As we get close… to 100 million HIV infections since the epidemic began- have we done as well as we should have?”
Dr. Kevin M. De Cock
In 1991, researchers successfully identified HIV (Human immunodeficiency virus) as the underlying cause of AIDS. Since then, scientific understanding of the disease has greatly improved. “Our success has made AIDS more normal, which has robbed the disease of some of its mystique,” De Cock expressed. However, there is still no known cure for AIDS. The disease is a lifelong battle that wreaks havoc on the people it infects.
De Cock and Curran’s contributions to the AIDS epidemic fundamentally shaped our understanding of the virus. Their work shines a light on the importance of frontline research and support. Their book, entitled ‘Dispatches from the AIDS Pandemic: A Public Health Story,’ is available to read here.
