The transmission route of hepatitis A, B, and C virus and its pathological changes on the liver

This study explored the globally prevalent pathogens, hepatitis viruses, and their significant impact on human health. This article mainly focuses on HAV, HBV, and HCV, aiming to provide a comprehensive reference for future studies. HAV is mainly transmitted through the gastrointestinal tract, while HBV and HCV are mainly transmitted through blood, body fluids, sexual contact, and mother-to-child transmission. Pathologically, HAV is mostly acute, while HBV and HCV tend to be chronic, which can easily lead to cirrhosis and even liver cancer. Analyzing the transmission mechanism and pathological changes of HAV, HBV, and HCV is crucial for preventing and controlling viral transmission, accurate diagnosis and treatment, formulating public health policies, and public health education. Understanding this information will help reduce the prevalence of hepatitis, improve treatment outcomes, and promote public health. However, the analysis of the structure of these viruses in existing studies is not sufficient. Future studies will further deepen the understanding of HAV, HBV, and HCV, promote vaccine and treatment innovation, and provide stronger support for the prevention and treatment of hepatitis.
