from exposure to infection
Aug 4, 1999

I have heard authorities say one needs exposure to get reasonable quantities of body fluids from and HIV+ person to get HIV.

1) Does this mean there is a minimum amount of virus needed in one's blood to contract HIV?

2) If so, what happens to if one gets less than that minimum amount in one's blod - say like a few virus particles. Do they: a) get cleaned up quickly by the body's immune system and will there be antibodies formed as a result? b) stay and take forever to replicate and grow and maybe show up years later as a positive test?

3) In the end, why can't just one viral particle infect?

Response from Dr. Holodniy

1. Probably, but we don't know that number. 2. Depends on the type of exposure and the underlying genetics and immune system of the person. I don't think it's b. 3. Theoretically it could. MH
