Don't get too excited by last week's news of a baby in Mississippi being "cured" of HIV, warns Mark Siedner in the Wall Street Journal—just because the baby had been exposed to HIV does not mean she was really infected with the virus. Most likely, the baby's heavy retroviral treatment prevented her from being infected by her mother's blood—indeed, today's medicines can drop the transmission rate in newborns from 30% to just 1%.
For the 30 million people around the world infected with HIV, "last week's news represents neither a path toward a cure nor support for discontinuing antiviral medicines," writes Siedner, himself an infectious disease researcher. Today's medicines can prevent the HIV from replicating and growing, but they cannot eliminate the virus from a body. However, the story is still good news for the thousands of pregnant women around the world diagnosed with HIV, notes Siedner, showing that the chances of their babies escaping from the virus are better than ever.
