Asymptomatic hepatitis B: care and prevention

Hepatitis B is a viral infection of the liver. A person can feel entirely well while blood tests still show infection. Test patterns help clinicians distinguish a recent infection from one that has persisted and assess whether the virus is reproducing or the liver is inflamed.

Monitoring may include liver enzyme tests, measurement of viral material in the blood and, when appropriate, liver imaging or an assessment of stiffness. Results over time guide whether observation is sufficient or antiviral treatment should be considered.

Attend planned liver reviews and take antiviral medicine exactly as prescribed if treatment has been started. Do not stop it without specialist advice. Avoid sharing razors, toothbrushes, needles or any item that may carry blood, cover open cuts, and do not donate blood.

Sexual and household contacts should be offered testing and hepatitis B vaccination if they are not immune. Use condoms until a clinician confirms a partner is protected. Hepatitis B does not spread through ordinary social contact such as hugging, sharing meals, coughing or using the same toilet.

Discuss alcohol, supplements and non-prescription medicines with the liver team because some can add strain to the liver. Tell healthcare and dental professionals about the infection when it is relevant to safe treatment. Pregnancy requires early clinical planning to reduce transmission to the baby.

Contact a clinician promptly if you develop yellow skin or eyes, dark urine, pale stools, persistent nausea, vomiting, pain under the right ribs, marked fatigue, itching, poor appetite or abdominal swelling. These symptoms can indicate liver inflammation or reduced liver function.

Seek urgent care for confusion, extreme drowsiness, vomiting blood, black tarry stools, severe abdominal swelling, fainting, or bleeding that is difficult to stop. Mention hepatitis B when arranging emergency assessment so the team has essential context.

Ask what your blood-test pattern means, whether the infection is recent or persistent, and how often liver checks are planned. Confirm whether treatment is indicated, which medicines or supplements to avoid, and how contacts can arrange testing and vaccination.
