What should you know about mode of transmission of viral hepatitis?

Hepatitis viruses do not all use the same route. Food- and water-borne infection is linked to swallowing contamination, while blood-borne infection can follow sexual contact, shared needles, unsterile equipment, or transmission from a parent to a baby around birth. Everyday contact such as hugging does not explain the spread of blood-borne hepatitis B.

Symptoms can be absent or mild. When they occur, fatigue, nausea, yellowing of the skin, or dark urine may reflect liver inflammation, but symptoms cannot identify the virus or confirm transmission. Blood testing is needed.

Wash hands after using the toilet and before preparing food, use safe drinking water, and avoid sharing needles, razors, or toothbrushes. Choose piercing and tattoo services that use sterile, single-use equipment. Vaccination can prevent some forms, including hepatitis B. After a blood or sexual exposure, seek advice promptly about testing and preventive options.

Arrange medical review after possible exposure, especially during pregnancy or after contact with blood. Prompt assessment is also appropriate for dark urine, yellow eyes, persistent vomiting, unusual fatigue, or pain beneath the ribs. A clinician may order hepatitis testing and a liver function test, then explain whether follow-up is needed.

Ask which hepatitis viruses fit the suspected exposure, which tests are appropriate, and whether vaccination or preventive treatment can help. Ask how to protect people at home and when repeat testing would give a clearer answer.
