Second baby "cured" of HIV
Last year, we learned researchers in Mississippi "cured" a baby infected with HIV.
The newborn was given a cocktail of medications usually reserved for advanced cases. The child is now 3 years old and the virus has not returned.
Now a baby born in California infected with HIV shows no sign of the virus after receiving the same treatment.
Thanks to good prenatal care and routine HIV testing of pregnant women in the US, cases of HIV transmissions from a mother to her newborn are rare - less than 200 a year.
