Forty-five years ago today, on June 5, 1981, the CDC published a brief report in the Morbidity and Mortality Weekly Report (MMWR) describing five cases of a rare pneumonia among young gay men in Los Angeles.
Those few paragraphs marked the beginning of the AIDS epidemic.
What followed was not only a public health crisis, but a crisis of neglect, stigma, and political indifference. The progress we celebrate today did not happen on its own. It was won by people living with HIV, activists, researchers, caregivers, and communities who demanded action when too many leaders remained silent.
As we mark 45 years since the first recognized AIDS cases, we encourage everyone to take a moment to read the original MMWR report, reflect on the lives lost and the movements built in response, and recommit ourselves to the work that remains.
Tonight, join us and our partners for the 7 Days in June vigil as we honor those we've lost, celebrate those who continue to fight, and remember why activism, science, and community still matter.
And if you're able, please support TAG and the many organizations working every day to advance HIV research, protect public health, and ensure that scientific progress reaches everyone who needs it.
The history of HIV is not over. The future is being written right now.
