Hepatitis in children generally refers to viral hepatitis. The main transmission routes of pediatric viral hepatitis are fecal-oral transmission, mother-to-child transmission, blood-body fluid transmission, and sexual transmission. And different types of viral hepatitis have different routes of transmission. Viral hepatitis can be categorized into 5 subtypes: A, B, C, D, and E. The transmission of viral hepatitis can be done through different ways. Hepatitis A and Hepatitis E are transmitted through fecal-oral transmission or by consuming water, food, toys and other items contaminated by virus carriers, so that the virus enters the mouth. Hepatitis B, D, and C are mainly transmitted by blood, mother-to-child, and sexually (children are generally not transmitted through this route). Children infected with viral hepatitis will have symptoms such as body fatigue, loss of appetite, anorexia, abnormal liver function and jaundice.
