Oh and by the way, AIDs and HIV aren't the same thing, so the title is incorrect, in that it should say HIV cure not AIDs.
I've never understood this separation (and neither did my partner who died of AIDS just over nine years ago). It seems to me to be just a "political correctness" conjuring trick, arising from the stigma associated with "AIDS" after all the doom and gloom "death"
ads of the 80's. It's for some bizarre reason more socially acceptable to say "I am HIV+" than "I have AIDS" and so people try and emphasise HIV+ rather than AIDS, which is silly. It's a disease and whatever you call it it's nasty!
Some generalisations (and this information is based on what I knew about 10 years ago, there may be better statistics available now):
The "average" person has a T-cell count of around 600 (this can vary wildly - some HIV- people can have a count of a couple of thousand, while others have figures as low as 400). The T-cell count is a very crude measurement of the health of a person's immune
system. Once someone has HIV this count typically decreases year on year, on average by between 50 and 150 t-cells a year. When the T-cell count gets to 200 is when symptoms of AIDS-associated illnesses tend to start to kick in. Pneumonia (PCP) is usually
the first to kick in at around this level and as the count reduces other nastier diseases show their hand.
It is usually when the first illness sets in that a person is described as having AIDS rather than being HIV+, but really it's just an indication that the continual weakening of the immune system over time has suddenly made the person unable to fight off an
infection - there is no real differenc between "AIDS" and "HIV+" as such.
It's important to remember that a T-Cell count is a VERY crude measure of the immune system. Just climbing the stairs or having a cold or missing sleep for a couple of nights can dramatically reduce it temporarily, and there are some HIV+ people who've got
down to single digit counts and seemed healthy where others have caught something at the 200 mark and died as a result of lack of timely treatment.
