Viral Hepatitis A
Overview
Viral hepatitis A is a liver infection caused by the hepatitis A virus, spread through contaminated food and water. Unlike hepatitis B and C, it does not cause chronic infection and most people recover fully.
Symptoms of Viral Hepatitis A
- Fatigue and loss of appetite
- Nausea and vomiting
- Abdominal discomfort, particularly in the upper right area
- Jaundice (yellowing of the skin and eyes)
- Dark urine and pale stools
- Many infections, especially in young children, cause mild or no symptoms
What Causes Viral Hepatitis A?
- Caused by the hepatitis A virus, spread through the faecal-oral route via food or water contaminated with the virus, or close contact with an infected person.
- Risk is increased by poor sanitation, unsafe water supply, and inadequate food hygiene.
How is Viral Hepatitis A Diagnosed?
- Diagnosed with a blood test for hepatitis A antibodies (IgM), which confirms a recent infection.
- Liver function blood tests support the diagnosis and help assess severity.
Treatment for Viral Hepatitis A
There is no specific antiviral treatment; management is supportive with rest, adequate fluids, and avoiding alcohol and medicines that stress the liver while recovering.
Most people, especially children, recover fully within a few weeks to a couple of months without lasting liver damage.
Severe cases with signs of liver failure (such as confusion or worsening jaundice) are rare but require urgent hospital-level care.
Because hepatitis A does not become chronic, once someone has recovered they generally have lifelong immunity.
How to Prevent Viral Hepatitis A
- Complete hepatitis A vaccination where available and recommended, particularly for travellers to endemic areas.
- Drink water from safe sources, or boil or treat water before drinking.
- Wash hands with soap after using the toilet and before preparing or eating food.
- Wash fruits and vegetables thoroughly and ensure food is properly cooked.
