Hepatitis A

Viral hepatitis; Infectious hepatitis

Symptoms will usually show up 2 - 6 weeks after being exposed to the hepatitis A virus. They are usually mild, but may last for up to several months, especially in adults.

Symptoms include:

• Dark urine
• Fatigue
• Itching
• Loss of appetite
• Low-grade fever
• Nausea and vomiting
• Pale or clay-colored stools
• Yellow skin (jaundice)

The doctor will perform a physical examination and may discover that you have an enlarged and tender liver.

Blood tests may show:

• Raised IgM and IgG antibodies to hepatitis A (IgM is usually positive before IgG)
• Elevated liver enzymes (liver function tests), especially transaminase enzyme levels
