Hepatitis is liver inflammation caused by various factors, primarily viral infections (types A, B, C, D, E), with differing causes and health impacts. While hepatitis A typically results in mild, acute illness with a viable vaccine, hepatitis B and C can lead to chronic conditions, cirrhosis, and liver cancer, necessitating specific management and vaccination strategies. Acute hepatitis is often resolved within six months, whereas chronic hepatitis involves ongoing liver damage with various clinical features and requires careful monitoring and potential referral for specialized treatment.
