Child Thought To Be Cured of HIV Relapses, Tests Positive Again 126
An anonymous reader writes: The Mississippi child, who was born with HIV passed from her mother, received HIV treatment for 18 months after her birth. In the course of over two years after the treatment, her blood indicated no trace of the virus or of HIV-specific antibodies, leading many to hope that she may have been cured completely. Earlier this month, however, the virus was detected again. Nearly 4 years old, the child is once more being given HIV treatment, and scientists are trying to figure out how she could have gone so long before relapsing.

GP implies stopping the drugs was the direct cause for the relapse.
The CNN article states the child was initially "functionally cured" a few months after stopping the drugs.
The facts us readers know, indicate neither correlation nor causation between stopping drugs and the relapse.

True, but HIV usually doesn't collectively decide to stay dormant in EVERY cell at once.
Either some unknown signalling pathway caused the HIV to stay inactive, or it was confined to a reservior that didn't somehow didn't leak for several years. Or she WAS cured, then reinfected.

The baby continued on antiretroviral treatment until 18 months of age, when the child was lost to follow up and no longer received treatment. Yet, when the child was again seen by medical staff five months later, blood samples revealed undetectable HIV levels (less than 20 copies of HIV per milliliter of blood (copies/mL)) and no HIV-specific antibodies. The child continued to do well in the absence of antiretroviral medicines and was free of detectable HIV for more than two years.
However, during a routine clinical care visit earlier this month, the child, now nearly 4 years of age, was found to have detectable HIV levels in the blood (16,750 copies/mL).
Hmm... I would assume that the #5 is correct (see bold portion in the quote from TFA). The only wrong info I am seeing is the "almost 4 years" instead of "4.5 years" time range...

A retrovirus is a single-stranded RNA virus that stores its nucleic acid in the form of an mRNA genome (including the 5' cap and 3' PolyA tail) and targets a host cell as an obligate parasite. Once inside the host cell cytoplasm the virus uses its own reverse transcriptase enzyme to produce DNA from its RNA genome, the reverse of the usual pattern, thus retro (backwards). This new DNA is then incorporated into the host cell genome by an integrase enzyme, at which p

How can you say that is most likely?
HIV does not spread easily. The panic times when people wore gloves and masks around the HIV infected are long gone, thankfully. The HIV virus spreading to family members is quite rare.
Diseases staying dormant for a long time is, however, not unusual at all.
So again, on what basis do you draw the conclusion that a re-infection is most likely?

Well, if it was a reinfection then I would expect the mother (or possibly father) to be the likely source. There are all kinds of ways that a mother could accidentally pass on the virus to a young child, especially if her infection isn't well-managed and the child isn't on anti-retrovirals. Could they tell the difference between the original infection and a reinfection if they came from the same source? I can't see how they could.

Why is this at all surprising? We know how HIV works and that it can hide in cells. So when someone is 'cleared' of it you can never be sure. The longer the drugs are taken increases the chances of clearing any dormant HIV (when it emerges). One can statistically figure out the best time to stop the treatment and many people could be free from reinfection for life but it is not a 100% certainty.
The only news is that a mother stopped the drugs too early.

There's a difference. Given that the human body sucks at fighting HIV, its not as if she did something and 'relapsed', the virus merely came back out of hiding from wherever it lurks (marrow, lymph, spleen, etc).

Untrue - some (many) mutations are bad, and the ones that change are the ones that die.
Evolution occurs when a mutation is a) beneficial and b) significant enough that it allows an animal to survive longer than those without that mutation. Being alive longer means they breed more. Breeding generally passes on the mutation.
It really is quite random, and there is no guarantee that the animals that change are better. Indeed for an animal that's particularly well suited to an environment that hasn't changed

They thought she might have been cured as she went two years without the meds without suffering a relapse. Typically, a relapse occurs within weeks of discontinuing the medication.
But that ended up bring wrong, as she eventually did relapse, so now they need to figure out why it took so long for that to happen.
