Hepatitis A - Management
How do I know my patient has it?
- Confirmed infection with hepatitis A is defined by:
- An acute illness with a discrete onset of symptoms (see Clinical features), and
- Jaundice or elevated serum aminotransferase levels (see Investigations), and
- Laboratory-confirmed IgM antibodies to hepatitis A virus (see Assay results).
- Probable infection is defined by:
- An acute illness with a discrete onset of symptoms, and
- Its occurrence in a person who has an epidemiological link with someone with laboratory-confirmed hepatitis A (for example a household or sexual contact during the 15–50 days before the onset of symptoms).
