Can you contract hiv virus if someone spits in your mouth?

Low risk: It is possible to transmit HIV through saliva, especially if it is contaminated with blood and if the recipient has any sores in the mouth. See this site for more info. http://www.cdc.gov/hiv/law/transmission.htm.

NO: Though it is a very grotesque experience, you cannot contract HIV virus with someone spitting in your mouth. However, i would make sure that person will never do the same thing to anybody else or even do the act of spitting again :).
