There are very small amounts of HIV in saliva, even on end-stage AIDS patients. For your own peace of mind, get tested for HIV-1/HIV-2 within 30 days of this incident, and again in 6 months.

"HIV has been found in saliva and tears in very low quantities from some AIDS patients. It is important to understand that finding a small amount of HIV in a body fluid does not necessarily mean that HIV can be transmitted by that body fluid. HIV has not been recovered from the sweat of HIV-infected persons. Contact with saliva, tears, or sweat has never been shown to result in transmission of HIV." From HIV and its Transmission Factsheet at http://www.cdc.gov/hiv/resources/factshe...

HIV is an enveloped virus. This means that in air, it is very easily denatured(or "killed"). The risk that you contracted the disease is somewhat unlikely, but I recommend that you get tested in a couple of months.

Depends if the salivia got into your mouth. How long ago was this exactly? Go to wikipedia and look up the symptoms (Ie fever, vomitting, thrush, headaches etc which can last up to a month) and if you get them then you should go to the doctor
