Can you get Hepatitis B from having sex?
Yes. You are at risk of contracting Hepatitis B if you have sex with an infected person without using a condom. You are at increased risk if you are sexually active and have unprotected sex with several different partners; this includes unprotected oral or anal sex. Hepatitis B is found in semen, vaginal fluids and anal mucus – so any sexual practice is risky without using protection, particularly rough sex where blood can be present.
Generally men who have sex with men (MSM) and sex workers (e.g. people who sell sex) are considered to be at higher risk of contracting Hepatitis B than heterosexuals. This is because of some riskier sexual practises among these groups.
If you identify as a man who has sex with men or you regularly have sex with different partners then you should speak to your local GUM Clinic about vaccination against Hepatitis B.
