Hepatitis viruses are a group of viruses that primarily affect the liver, causing inflammation and damage. The most common types are Hepatitis A, Hepatitis B, Hepatitis C, Hepatitis D, and Hepatitis E. Each virus is transmitted differently, with some spread through contaminated food and water, while others are transmitted through blood or sexual contact. Infection with hepatitis viruses can lead to various health issues, ranging from mild illness to severe liver disease, including cirrhosis and liver cancer. Vaccines are available for Hepatitis A and Hepatitis B, but there is no vaccine for Hepatitis C or Hepatitis E. Early detection and treatment are crucial for managing these infections.
