The gains the world has made against AIDS are "inadequate and fragile," U.N. Secretary-General Ban Ki-moon told reporters today.
More than half the people around the world infected with HIV, or 20 million people, still don't have access to treatment, he said.
Countries have pledged to end AIDS by 2030, but activists say more funding is needed, especially to fight tuberculosis, the leading cause of death for people with HIV.
