Viral hepatitis is a type of liver inflammation caused by a viral infection. There are five main types of viral hepatitis, including hepatitis A, B, C, D, and E. Each type is caused by a different virus and has different modes of transmission and health outcomes. Research in the area of viral hepatitis focuses on understanding the transmission, prevention, diagnosis, treatment, and long-term effects of the disease. This includes studying the impact of vaccination programs, antiviral therapies, and public health initiatives on reducing the burden of viral hepatitis globally. Researchers also investigate the molecular biology of the viruses that cause hepatitis, the immune response to infection, and the development of new diagnostic tools and treatment strategies. Overall, research in viral hepatitis aims to improve prevention, diagnosis, and management of the disease to reduce its impact on individuals and public health.
