GREAT NEWS! – HIV infection rate has fallen dramatically in U.S.

New calculations to better track HIV infections confirm that the U.S. is seeing a strong and steady decline.

The number of new cases has been falling for years. But health officials wanted a clearer picture of how the epidemic was behaving. They count people when they were diagnosed with the AIDS virus — not when they actually contracted it, which can be months or years earlier.

Counting infections instead of diagnoses is a more ideal gauge — a kind of speedometer that tells how fast the epidemic is actually moving, said David Holtgrave, an HIV researcher at Johns Hopkins University.

The Centers for Disease Control and Prevention used blood test results to help date the infections. Their calculations showed new infections dropped by nearly 18 percent over six years, the CDC reported Tuesday. Though health experts expected a decline, they welcomed the confirmation.

“It’s very exciting to see this kind of drop,” said Ron Brookmeyer, a statistician at the University of California, Los Angeles.
