I don't think you have anything to worry about. The only way hiv can be transmitted is if hiv infected blood, semen, or vaginal fluids gets into your bloodstream. Even though hiv is in saliva, urine, sweat, and tears, it is in such small amounts that it would be extremly rare to become infected by these fluids. The CDC has a fact sheet that tells you how hiv can and cannot be transmitted. Check it out at www.cdc.gov/hiv/pubs/facts/transmission.htm (http://www.cdc.gov/hiv/pubs/facts/transmission.htm)
I hope this helps.
