Editing Pathogen transmission (section)

====Oral sex====
[[Sexually transmitted infection]]s such as HIV and hepatitis B are thought to not normally be transmitted through mouth-to-mouth contact, although it is possible to transmit some STIs between the genitals and the mouth, during oral sex. In the case of HIV, this possibility has been established. It is also responsible for the increased incidence of [[herpes simplex virus]] 1 (which is usually responsible for oral infections) in genital infections and the increased incidence of the type 2 virus (more common genitally) in oral infections.{{citation needed|date=September 2015}}
