The point is. If you have HIV and not already AIDS you take ARVs and they`ll probably work a long long time untill you get AIDS. Probably you will never get AIDS. But if you didnt take ARVs and you get AIDS youve got a problem because they then wont work that good anymore because with AIDS it is some other infections that will finally kill you it is not HIV (althouh it leads to that situation) so if there are several infections Herpes, RNA viruses, bacteria and so on and you only treat the Retrovirus you might never get better. I guess those people who significantly improved at the WPI didnt just take ARVs alone.
Annette Whittemore told in her interview at Nevada news that "Andrea is doing well" and it took about a year for the Treatment to work.
I dont think it is good to force a silence of the immune system if there might be an or several infections as Levy suggest. This is not the key but it is typical for school medicine not to tear out the root but to scrach just the surface.
