But as billionaire Bill Gates recently noted, without the proper funding, the virus could make a dangerous resurgence.
The Bill and Melinda Gates Foundation this week published the first-annual "Goalkeepers" report — an exhaustive document that identifies and tracks more than a dozen measures of global public health, including child mortality and family planning.
The foundation plans to release a report every year until 2030, keeping tabs on the progress made on each metric along the way.
HIV infection is one of the first metrics listed in the 2017 "Goalkeepers" report.
At last count, there were 36.7 million people worldwide living with the virus, roughly 1.8 million of whom were children under 15 years old.
People seem to be getting complacent with the progress that's been made over the last 15 years, Gates wrote, "and now there's talk of cuts."
