That's 240,000 people. Treatment: All told, about three-quarters of those infected are not getting adequate treatment to keep the virus in check, thus raising the risk that it gets passed along. New infections: About 50,000 are newly diagnosed with HIV each year, and the lifetime cost of care is currently pegged at $367,000. “The HIV crisis in America is far from over,” says the director of the Division of HIV/AIDS Prevention at the CDC, as quoted by WebMD. “Closing the gaps in testing, care, and treatment will all be essential to slowing or reversing the US AIDS epidemic."
