Anyone got a link to a "legitamite" news source with this info? |
The New York Times, legitimate enough for you ? :P

If this is gonna be any similar to what has happened to antibiotics, the virus is going to become resistant eventually to those drugs, too; am I correct? |
Mmm, in my admittedly limited understanding, these drugs don't work on the virus directly as such, they interfere with the cell's ability to transcribe RNA, effectively making the cell ignore the virus's instructions. The nasty side effects of anti-retrovirals are due to the natural consequences of screwing with biology on a cellular level...they're only valuable as the lesser of two evils. So I don't get how people could be "disguising the symptoms" with anti-retrovirals and going out and having sex. I'd read that the drugs have rather plain side effects, including big unsightly swellings, and are sufficiently non-fun to live with that they won't put you in the mood for sex. Fo gigure.
Anyway, the reason bacteria become resistant to antibiotics, which don't do a thing against viruses, is that they directly attack the microbe's function, which the germs adapt to as all populations will to attacks. Vaccinations, the traditional weapon against viruses, essentially train the host to recognize a virus by pitting it against a harmless relative, kind of like the way people once trained new attack dogs by pitting them against old, toothless ones. Anti-viral drugs are a fairly unusual thing, given the primitive nature of viruses; my intuition would be that the virus would have to basically reinvent the pathogenic wheel in order to get around a transcription blocker. But again, I'm not a biologist.

The farce is strong with this one.

Wait, they deliver reverse transcriptase inhibitors as a virus! If they only give you the inhibitor, then it couldn't be integrated into the genome. |
What? Reverse transcriptase inhibitors are intaken (often orally), and as it is an irreversible competitive inhibitor to thymidine it blocks up the active site of reverse transcriptase. As it is all statistical due to the relative concentrations, it won't stop the virus but significantly slow it down.
There are also interferons which can be administered. They are usually secreted when a cell is in distress which tells neighbouring cells to 'brace themselves' for a viral attack by slowing down rates of protein synthesis. The logic behind this is that if the rate of protein synthesis from mRNA then the virus is slowed because it will take much longer to produce viral protein components. And give the immune system a better chance against it.

Think about it.
All other factors being equal (which im not claiming, we just dont know here) , meaning same rate of transmission etc, a shorter time for the disease to manifest itself can only DECREASE its epidemic potential, which on a global scale is a GOOD thing.
If the you had AIDS the day you became infected and died immediatly, you can bet there would be much fewer victims today.
This is extreme but my point still stands.
