What should you know about the mode of spread of hepatitis B?

The virus can enter the body through broken skin or mucous membranes. Exposure can occur through sex, from an infected parent to a baby around birth, sharing needles or other equipment that may carry blood, or unsterile tattooing, piercing, or medical equipment. A person can carry the virus without feeling unwell, so appearance alone cannot show whether someone is infected.

Hepatitis B is not spread by ordinary social contact such as hugging, sharing food, coughing, or using the same toilet. Do not share razors, toothbrushes, or items that may have blood on them, and cover open cuts carefully.

Tell a clinician promptly about the type and timing of exposure, whether blood was involved, and your vaccination history. Testing can include blood tests, and a Liver Function Test may be used to assess liver health, although it does not replace tests for the virus.

Ask about Hepatitis B Vaccination if you are unvaccinated or unsure of your protection. A clinician can also explain testing for a partner or household contact and practical steps for avoiding blood exposure while results are being clarified.

Seek prompt medical advice after a needlestick, sexual exposure, contact with infected blood, or an exposure during pregnancy. Urgent assessment matters because preventive care may depend on how recent the exposure was. Arrange review for yellowing of the skin or eyes, dark urine, unusual fatigue, vomiting, abdominal pain, or confusion.

Ask: Was this exposure capable of transmitting hepatitis B? Do I need testing or vaccination? Should my partner or household contacts be tested? Which symptoms require urgent help? How should I protect others while my status is being assessed?
