Hepatitis B is a liver infection that is spread through blood, semen and vaginal fluids. The chance of getting it in the UK is low. The infection usually only lasts for a few months, but some people can have hepatitis B long term.
Vaccination is the best way to prevent hepatitis B. A hepatitis B vaccine is available as part of routine child vaccination, or if you’re at higher risk. Find out more about vaccination
Other ways to reduce your risk from hepatitis B include:
- using a condom when having vaginal, anal, or oral sex;
- avoiding sharing razors, toothbrushes, and needles with others.

Symptoms
Many people with hepatitis B won’t have any symptoms. If you do develop symptoms, they tend to occur 2 or 3 months after exposure to the hepatitis B virus.
Symptoms of hepatitis B include:
- Tiredness
- A high temperature (fever) of 38°C or above
- General aches and pains
- Loss of appetite
- Feeling and being sick
- Diarrhoea
- Abdominal pain
- Yellowing of the skin and eyes (jaundice)
Hepatitis B usually clears up on its own without treatment. Your GP will refer you to see a liver specialist who will check how well your liver is working.
