Hepatitis E is a viral infection that primarily affects the liver. It is caused by the hepatitis E virus (HEV) and is usually transmitted through contaminated water or food. Symptoms can include fatigue, jaundice, and abdominal pain, but many people may not show any symptoms at all. The infection is more common in areas with poor sanitation and can lead to serious complications, especially in pregnant women. Most people recover fully without treatment, but in some cases, it can become severe. Preventive measures include ensuring access to clean water and practicing good hygiene.
