Hepatitis B and Hepatitis C are viral infections that primarily affect the liver. Hepatitis B is caused by the hepatitis B virus (HBV), while Hepatitis C is caused by the hepatitis C virus (HCV). Both viruses can lead to acute and chronic liver disease, including inflammation, cirrhosis, and even liver cancer. Hepatitis B is transmitted through contact with infected blood or bodily fluids, while Hepatitis C is mainly spread through blood-to-blood contact, often via sharing needles or unsafe medical procedures. Symptoms may include fatigue, jaundice, abdominal pain, and nausea. Treatment options vary but can include antiviral medications and, in some cases, liver transplantation. Vaccines are available for Hepatitis B but not for Hepatitis C. Early detection and management are crucial to prevent long-term liver damage.
