HIV tests typically begin with an antibody test. After an antibody test comes up positive, a followup Western Blot test is typically performed (in the US anyway - I have no idea of the testing methods used elsewhere, particularly in the Third World).
An antibody test will always come up as positive after you've been exposed to the virus. The antibodies don't go away.
The Western Blot test measures viral load. This can come up as "undetectable, which simply means no viral particles were found in teh sample,. This doesn't mean a person has been "cured," but it can be interpreted as a "negative" result.
This is probably what happened - a person tested positive on an antibody test, and came up with an undetectable viral load on the Western Blot. It's not uncommon. Once a person is on medication, it's much more common to test as undetectable.
A person can only really be said to be "cured" of HIV if their viral load is still undetectable after a significant amount of time without drug therapy - obviously, that's rather risky to test. But "a few weeks" is nowhere near long enough to verify that a person is HIV-free, as Cedre's proposed.
The point is that "I tested positive, and now I test negative" is both woefully oversimplified as far as what tests are performed, and completely irrelevant if insufficient time has passed. We don;t even know if the individuals in question were taking medication, the tests done initially and after their supposed "cure," the lab that performed the test...
There's a reason the medical community is not endorsing "Faith healing" as a cure for HIV
Yeah that seems like it, although it would be good to know the tests used in Africa.
I'd like to see a source for that.
I know that there are some people who have a genetic resistance to HIV and will test positive on an antibody test (showing that they've definitely been exposed), but will never display a detectable viral load, never show a drop in T-cells, and generally will be like someone exposed to any other disease but didn't get sick.
Made the news here in Canada maybe two years ago, tried to find an article about it. I remember it was a person who was diagnosed with type1 AIDS (or however they rank it, it was still in its initial stages) and then had the flu (or some other thing, I'm not 100% sure) and his doctor realized he didn't have AIDS anymore.
