A VIRAL LIVER INFECTION FROM CONTAMINATED FOOD OR WATER
Hepatitis A
A viral liver infection spread through contaminated food and water, causing fatigue, nausea, jaundice and abdominal discomfort. Usually self-limiting with full recovery; preventable by vaccination.
ABOUT THIS CONDITION
What is Hepatitis A
Hepatitis A is a viral infection of the liver caused by the hepatitis A virus, spread primarily through contaminated food and water and by close contact in unhygienic conditions. The illness typically begins with tiredness, nausea, loss of appetite, low-grade fever and abdominal discomfort, followed within a few days by yellowing of the skin and eyes (jaundice), dark urine and pale stools. Most patients recover fully within a few weeks without specific antiviral treatment, and the infection does not become chronic. However, in rare cases — particularly in older adults or those with underlying liver disease — it can cause severe acute liver failure. Diagnosis is confirmed with blood tests. Treatment is supportive, focused on rest, hydration, nutrition and avoiding alcohol and certain medications. Vaccination provides effective long-term prevention, and good hygiene reduces the risk of transmission. Dr. Patnam Pravallika Reddy provides accurate diagnosis and complete care at Lux Hospitals, Hyderabad.
