Well even if that was the case, the virus goes to fluids with carry DNA strands. It attacks the white blood cell count by disguising itself as a white blood cell. White blood cells are key to providing immunity.

So blood and semen carry DNA, but saliva doesn't, it's just a secretion to help digest food. So you're safe when it comes to saliva and boogers (unless it's a bloody booger and you like, ate it :hsugh: )

Most people don't actually die from AIDS, they die from some other normally benign virus that can grow much stronger in a weakened host.

Bronchitis --> Pneuomnia is a common one.
