SymptomsBy Mayo Clinic staff
Hepatitis A signs and symptoms typically don't appear until you've had the virus for a few weeks. Signs and symptoms of hepatitis A include:
- Nausea and vomiting
- Abdominal pain or discomfort, especially in the area of your liver on your right side beneath your lower ribs
- Loss of appetite
- Low-grade fever
- Dark urine
- Muscle pain
- Yellowing of the skin and eyes (jaundice)
Signs and symptoms of hepatitis A usually last less than two months, but may last as long as six months. Not everyone with hepatitis A develops signs or symptoms.
When to see a doctor
Make an appointment with your doctor if you have signs or symptoms that worry you.
If you've been exposed to hepatitis A, you may prevent infection by having a hepatitis A vaccine or immunoglobulin therapy within two weeks of exposure. Ask your doctor or your local health department about receiving the hepatitis A vaccine if:
- A restaurant where you recently ate reports a hepatitis A outbreak
- Someone close to you, such as someone you live with or someone who is your caregiver, is diagnosed with hepatitis A
- You recently had sexual contact with someone who has hepatitis A
- You recently shared needles for self-injected drugs with someone who has hepatitis A
