hiv

It was huge (huge!) news last year when a team of doctors led by Johns Hopkins virologist Dr. Deborah Persaud announced that they had effectively cured a baby born with HIV. This week, doctors announced that a second baby born with HIV was treated with a similar regimen โ€” and after undergoing ultrasensitive tests to detect the virus, has also been declared HIV-free.

(Also โ€“ just to get this out of the way โ€“ youโ€™re not technically supposed to say that these babies have been cured. They are still on antiretroviral drugs. However, if you test their blood, you donโ€™t find any evidence of the virus. Persaud prefers the phrase โ€œhaving sero-reverted to H.I.V.-negative.โ€ But, well, thatโ€™s kind of clunky.)

This second success is a big deal, because some people questioned whether the infant Persaud cured was even born with the disease at all. Tests of this babyโ€™s blood and spinal fluids revealed clear evidence of the disease, which means she was definitely infected at birth. She was immediately started on the drug regimen; six days later, the virus started vanishing, and eleven days after it was completely undetectable โ€” even when Dr. Persaud used a particularly sensitive kind of test.

Although this particular cure came out of a hospital in Long Beach, California, weโ€™ll congratulate Dr. Persaud for her part, too. Hereโ€™s to many more cures in the future!
