Scientists have announced that a toddler in Mississippi has been cured of HIV -- and that news is electrifying researchers in the Bay Area.

California reported the largest number of HIV diagnoses in the country in 2011, according to the Centers for Disease Control -- and more than 60 percent of Californians with HIV live in Los Angeles or San Francisco.

In the case of the HIV-positive Mississippi baby, the child was given three drugs within 30 hours of birth. Two years later, the virus is undetectable in the child's blood. Doctors say the finding could be a game-changer.

Host Mina Kim talks with Dr. Deborah Cohan, an obstetrician at UC San Francisco who specializes in the care of pregnant women with HIV.
