So a child in Mississippi was born to a mother who had been recently found that she was HIV positive. 30 hours after the child's birth the child was started on drugs that are typically given to people who are HIV positive. These drugs were actually given to her prior to the child officially being diagnosed with HIV because the main doctor felt that the chances of the child being HIV positive was high enough that it was worth it. It was suggested that this drug treatment worked because;
"...before [the virus] could form hideouts in the body."
This means that this treatment might lead to a cure for children diagnosed with HIV. Which is incredible.
