As the son of a pioneering HIV advocate and as someone born with the virus, I know that truth firsthand. In 1981, my mother, Elizabeth Glaser, contracted HIV during a blood transfusion while giving birth to my sister, Ariel. Together, we’ve saved 26 million lives, prevented 4.4 million children from acquiring HIV, and ensured 77% of people living with HIV now have access to treatment powerful enough to suppress the virus to undetectable, untransmittable levels. So, with all this progress—with the tools and knowledge to end HIV as a public health threat—why haven’t we crossed the finish line? We can — and must — finally bring an end to the HIV epidemic.
