One question that is just hard to find the answer too
What are the chances that Hepatitis B can be transmitted via oral sex? And are the chances lower for the guy that receives oral from the girl and higher for the guy that performs oral on the girl? Everywhere I read it says low risk, no risk, unproven, or easily but then it also says that HepB is 100 times more contagious then HIV, so that means oral sex is a easy way to get it right?
HBV is usually spread through intercourse or injection drug use. Oral sex may be a mode of transmission theoretically because saliva can contain hepatitis B. However, most epidemiologic links between HBV and transmission associate acquisition of infection with vaginal or anal intercourse and not oral sex per se.
HBV is more contagious than HIV through exposure from a needle or through vaginal or anal intercourse.
