HIV & AIDS

The number of people diagnosed with HIV each year in the United States has declined overall in the last decade, but there have been increases in among young gay men, a new study finds.

A 46 year-old woman in Texas likely acquired HIV from her female partner in what health officials say is a rare case of female-to-female transmission of the virus.

One woman's uncommon ability to fight her HIV infection may provide new insights for developing a vaccine that triggers a special immune response against the viral disease, researchers said.

Shivering triggers a similar response in skeletal muscle as exercise does, so drugs that trigger the response could one day be used as weight-loss aids.

A Mississippi baby born with HIV and treated in the early hours of her life remains free of the infection three years late, despite being off of medications for 18 months, according to a new report.
