It can be spread sexually where the sex involves any contact with an infectious person's anus or faeces. Penetrative sex, especially without a condom, oral sex, and rimming can all spread Hepatitis A.
The other route is through foods which have been contaminated by faeces or by someone with Hepatitis A who has not been scrupulous in hand washing before food preparation.
Hepatitis B has two main routes of spread. It can be spread sexually or by contaminated blood supplies or medical products like needles and syringes.
Hepatitis B is very infectious and can be spread easily from someone who is infectious. Unprotected oral sex, penetrative sex and rimming can spread Hepatitis B infection. Not everyone who has had Hepatitis B is infectious. Most become immune and non-infectious.
Hepatitis B can also be spread by contamination of the medical blood supply, by sharing dirty needles or by being treated with inadequately cleaned instrumentation. This happens rarely in the UK but may occur in other countries especially in the developing world.
Hepatitis C has two main routes of spread. It can be spread sexually or by contaminated blood supplies or medical products like needles and syringes or by instruments used in body piercing or tattooing.
Hepatitis C is very infectious and can be spread easily from someone who is
infectious - but generally only if there is blood to blood contact. It can be spread sexually, particularly in association with other infections. If there is no blood to blood contact eg sharing toothbrushes or razors, or sexual contact then Hepatitis C cannot be passed on. Social contact with people with Hepatitis C does not result in infection.
Hepatitis C can also be spread by contamination of the medical blood supply although this is now very unlikely in the UK. Sharing dirty needles for injecting drugs eg crystal meth or by being treated with inadequately cleaned instrumentation may also pass on Hepatitis C.
Snorting cocaine through shared straws or rolled bank notes is thought to be an
increasingly common way to spread Hepatitis C.
Thank you for the reply. It sounds like it is mostly blood to blood same as hiv. I am only nervous because I was given oral sex and and was rimmed. I did not perform on him. What do you think the chances are?
