What should you know about CDC hepatitis A?

Hepatitis A affects the liver and commonly spreads when tiny amounts of infected stool reach food, water, hands, or shared surfaces. Feeling generally unwell, nausea, loss of appetite, abdominal discomfort, dark urine, and yellowing of the eyes or skin can occur. Children may have mild or unnoticed illness, while adults can feel very tired and unwell.

The infection does not usually become a long-term liver infection, but symptoms can be prolonged and dehydration or severe illness can occur. Avoid preparing food for others while unwell, wash hands thoroughly after using the toilet, and follow local clinical advice about close contacts.

Contact a clinician if you have compatible symptoms, have travelled to an affected area, eaten a possible source food, or had close contact with someone diagnosed with hepatitis A. The clinician may arrange blood tests and review your liver function. Rest, drink enough to avoid dehydration, and choose tolerable foods; avoid alcohol and check before taking medicines that can affect the liver.

Ask about hepatitis A vaccination if you are not protected, are planning travel, or have had a possible exposure. Vaccination and hygiene help prevent spread, but vaccination does not replace assessment when symptoms are present.

Seek prompt medical advice for dark urine, yellow skin or eyes, persistent nausea, loss of appetite, or unusual tiredness after a possible exposure. Seek urgent care for repeated vomiting, inability to drink, confusion, severe abdominal pain, bleeding, or rapidly worsening weakness. Tell the clinician about travel, food and water exposure, contacts, and all medicines you take.

Ask which tests can clarify the cause, whether your liver function needs monitoring, how to reduce household spread, and whether vaccination is suitable for you or close contacts. Confirm which medicines and foods to avoid while your liver is recovering and when normal activities can resume.
