How hepatitis B spreads

Transmission can occur when infected blood or body fluids enter another person’s body through sex, shared needles or injecting equipment, contaminated tattoo or piercing equipment, or contact with an open wound. A baby can acquire the virus around birth. The virus is not spread by ordinary social contact such as hugging, sharing food, coughing, or using the same bathroom.

Some people have no symptoms, while others develop tiredness, nausea, abdominal discomfort, or Dark Urine. A person can carry and pass on the virus without feeling ill, so testing is based on exposure and clinical advice rather than symptoms alone.

Do not share needles, razors, toothbrushes, or equipment that may contain blood. Use sterile equipment for tattoos and piercings, cover cuts, and use barriers during sex until a clinician confirms protection. Hepatitis B Vaccination is an effective preventive measure for people who are eligible. After a possible exposure, seek medical advice promptly because testing and preventive treatment may be time-sensitive.

Contact a clinician after sexual contact, needle sharing, a needlestick, or blood contact involving someone who may have Hepatitis B. Arrange assessment for persistent Fatigue, yellowing of the skin or eyes, or Dark Urine. A Liver Function Test may be part of an evaluation, but blood tests that detect the virus and immune response are also needed to clarify infection and protection.

Ask whether you need hepatitis B testing, vaccination, or post-exposure care. Tell the clinician when the contact occurred, what type of exposure happened, and whether you have a vaccination record or known liver condition.
