Im not sure why it is interesting. These doctors do not say what they base their findings on, nor if their conclusions are based on clinical study or specific research.
Statements such as, "HIV can be transmitted by oral sex, though this does not occur frequently" doesn't mean much. Can be? How possible? Can be as it has happened before, or can be hypothetically? Can be, as in if a person with massively bleeding gums gives head to a guy with a large cut on his penis?
This article was way too vague for me to hold my interest at all.
