Im not sure thats real great news. Apologies for sounding so heartless but: The ability to hang around for 15 years, potentially infecting more people, is the downside view.
I happen to just be finishing reading Letters to a young conservative by Dinesh DSouza (great book) and he tells of running polls when he was working on the Dartmouth Review questioning how to deal with AIDS. The vote came up to have a tattoo on the butt of anyone testing positive. Then they ran polls to vote on what the tattoo should say. The winner: "Abandon hope, all ye who enter" (poking fun at The Left was made into great sport at Dartmouth Review)
Oh..so when it comes to those who contract diseases that could potentially infect others...the sooner they die the better.
You're right..that is heartless.
