Hepatitis refers to an inflammation of the liver, which can be caused by a range of factors, including viruses, alcohol abuse, and certain medications. Viral hepatitis is a group of diseases caused by different viruses, including hepatitis A, B, C, D, and E. These viruses can lead to acute and chronic liver disease, liver cancer, and even death. Hepatitis A is transmitted through contaminated food and water or close contact with an infected person. The symptoms of hepatitis A include fever, fatigue, and loss of appetite, nausea, and jaundice. Most people recover from hepatitis A within a few weeks with no long-term effects, and there is a safe and effective vaccine available to prevent infection. Hepatitis viruses are a group of highly infectious and potentially lifethreatening viruses that attack the liver and cause inflammation. There are five main types of hepatitis viruses: A, B, C, D, and E. Each type of hepatitis virus has different modes of transmission, clinical features, and outcomes. Hepatitis A and E are primarily transmitted through contaminated food or water, while hepatitis B, C, and D are transmitted through blood and body fluids. Hepatitis A is typically a self-limiting disease, and most people recover without any complications. Hepatitis B, C, and D, on the other hand, can cause chronic infection, which can lead to liver cirrhosis, liver failure, and liver cancer. Hepatitis B is preventable through vaccination, while hepatitis C can be cured with antiviral therapy. There is currently no cure for hepatitis D, but treatment is available to manage symptoms and slow disease progression.
