Can kissing be a cause of catching aids/HIV?
There is no scientific evidence indicating that any person has ever become infected through kissing an HIV positive person. To become infected with HIV you must get a sufficient quantity of the virus into the bloodstream. Saliva does contain HIV, but the virus is only present in very small quantities and as such cannot cause HIV infection. Unless both partners have large open sores in their mouths, or severely bleeding gums, there is no transmission risk from mouth-to-mouth kissing.
