Hepatitis A Vs Hepatitis B

Hepatitis A is a highly contagious viral infection that primarily affects the liver. It is caused by the Hepatitis A virus (HAV), which is typically transmitted through the ingestion of contaminated food or water or through close contact with an infected person. Symptoms often include fatigue, nausea, abdominal pain, loss of appetite, and jaundice. While Hepatitis A can be a short-term illness, it does not lead to chronic liver disease, and vaccination is available to prevent infection.

Hepatitis B is a serious liver infection caused by the Hepatitis B virus (HBV), which can lead to chronic disease and increase the risk of liver failure, liver cancer, and cirrhosis. The virus is transmitted through contact with infected bodily fluids, including blood, semen, and vaginal secretions, often through sexual contact, sharing needles, or from mother to child during childbirth. Symptoms may include fever, fatigue, and jaundice, and while there is no cure, a vaccine is available to prevent infection, along with antiviral medications to manage chronic cases.
