Whether or not an event will result in an AIDS infection depends mainly on whether or not the bodily fluids of the contact in question contain a high amount of HIV, and the other is the manner in which the contact was made. In the case of drinking the blood of a person with AIDS, if the person with AIDS has a high amount of HIV in his or her blood circulation, there is a possibility of infection because it is in contact with the mucous membranes of one’s mouth and digestive tract. If there are mouth ulcers or if there is gastrointestinal bleeding, there is a greater likelihood that this blood will cross directly over the mucous membranes and come into contact with the wounds and with the blood circulation, thus causing infection. If an AIDS patient has taken the appropriate oral antiviral medication, the amount of HIV in the blood is extremely minimal. After drinking in this case, the likelihood of infection is also significantly reduced, and it is even less likely to cause transmission.
