Scientists from the University of Washington in Seattle concluded that while saliva may be infectious, the strongest predictor of viral presence in the saliva is serum viral load. Transmission. Hepatitis B virus (HBV) is highly contagious and may be present in blood and body fluids, including semen and vaginal secretions. The saliva of people with hep B may contain evidence of the virus but in such small concentrations that kissing does not spread HBV. Hepatitis A requires some form of fecal exposure (which would include contaminated water or food), and is not spread via saliva or kissing. Kissing is, in general, not considered a risk factor for HIV transmission. It would only be a risk if bleeding occurred or open sores were present. In September of 2003, evidence that saliva contains the Hepatitis C virus was disclosed at the Interscience Conference on Antimicrobial Agents and Chemotherapy.
