What should you know about etiology of hepatitis A?

The virus can pass from tiny amounts of infected stool into the mouth. This may happen when handwashing is inadequate, through unsafe food or water, or during close household or sexual contact. It does not become a long-term infection in the same way as some other viral hepatitis types. Feeling generally unwell, nausea, loss of appetite, and dark urine can occur as the liver responds to infection; some people have few or no noticeable symptoms.

Arrange medical advice if hepatitis A is suspected. A clinician may assess symptoms and liver health with an examination and blood tests such as a liver function test. Rest, fluids, and light meals can help while you recover. Wash hands carefully after using the toilet and before preparing food, and avoid preparing food for others while unwell. Ask about hepatitis A vaccination after an exposure or before travel when relevant.

Seek urgent medical help for confusion, unusual sleepiness, repeated vomiting, severe dehydration, or rapidly worsening yellowing of the skin or eyes. Contact a clinician promptly if you cannot keep fluids down, your urine becomes very dark, or you are pregnant or have existing liver disease.

Could my symptoms be hepatitis A, and which tests would confirm it? How should I protect people at home? Do I need vaccination or follow-up for my liver?
