Liver infections occur when harmful microorganisms, such as viruses or bacteria, invade the liver, leading to inflammation and damage. Common types include hepatitis A, hepatitis B, and hepatitis C, which are primarily caused by viral infections. Symptoms may include fatigue, jaundice (yellowing of the skin and eyes), and abdominal pain. Treatment for liver infections depends on the cause. For viral infections like hepatitis, antiviral medications may be prescribed, while bacterial infections might require antibiotics. Preventive measures, such as vaccination for hepatitis A and hepatitis B, along with practicing good hygiene, can help reduce the risk of liver infections.
