Viral hepatitis may be contagious in children’s hepatitis, but it is not contagious due to autoimmune or drug damage. Clinically, hepatitis is categorized into acute and chronic hepatitis and viral hepatitis, alcoholic hepatitis, autoimmune hepatitis, hepatitis A, hepatitis B, hepatitis C and hepatitis D according to the causative factors, infectious viruses, duration of the disease and clinical manifestations. If a child has hepatitis A, B, C, D, or E, it is usually contagious; while other types of hepatitis, such as those caused by autoimmune factors or drug damage to the liver, are generally not contagious. For hepatitis A, B, C, D, and E, transmission occurs mainly through fecal-oral, blood, and body fluids. Hepatitis usually causes nausea and vomiting, loss of appetite, abdominal distension, itchy skin, mental depression and other symptoms, which affect the quality of life and health. It is recommended that children diagnosed with hepatitis actively cooperate with doctors for treatment. If hepatitis is clearly contagious, pay attention to isolation during the treatment period, maintain personal hygiene and ensure sufficient rest time.
