They don't actually see the real world, where 95% of the people with HIV are not treated and are dying. And even though we have some blue sky now in our country, the sky could become cloudy again very soon.
I think we should put the same weight now on the co-factors as we have on HIV.
We can be exposed to HIV many times without being chronically infected. Our immune system will get rid of the virus within a few weeks, if you have a good immune system.
