If you actually read this page you will see "HIV is not spread through saliva" stated several times.
Now just to clear up 2 point since you're obviously dense as fuck.
1- HIV and AIDS are transmitted exactly the same way and for that reason the CDC has one web page for the two of them.
2- The CDC is the "Center for Disease Control" and they know far more about AIDS than you ever will.
