Viral hepatitis can be categorized based on its cause into hepatitis A, B, C, E, and D. For hepatitis A and E, it is generally acute and usually has a good prognosis without severe consequences. However, hepatitis B and C often lead to chronic hepatitis, progressing into chronic viral hepatitis, then to cirrhosis and even liver cancer, which can affect quality of life and lifespan.

How to prevent viral hepatitis

For Hepatitis A and E, the main mode of transmission is fecal-oral, thus the key to prevention is to prevent fecal-oral transmission by enhancing protection of water sources and food, such as personal hygiene and improved management of feces. Hepatitis B, C, and D are mainly transmitted through blood and bodily fluids. Therefore, to prevent these types of hepatitis, it is necessary to avoid unsafe sexual practices with infected individuals, avoid contact with their blood, and for mothers with hepatitis B, antiviral treatment is necessary to prevent transmission to newborns.

How is viral hepatitis transmitted?

Viral hepatitis comes in many types, with its main pathogens including hepatitis A, B, C, D, E, and others. Each type targets different transmission pathways; for example, hepatitis A and E are primarily transmitted via the digestive tract. They can spread through fecal-oral transmission, and ingesting contaminated food can lead to the dissemination of hepatitis A or E. For hepatitis B, the main transmission routes include mother-to-child transmission, blood and body fluid transmission, and close personal contact can also lead to the transmission of hepatitis B. As for hepatitis C, the primary transmission method is through transfusion of blood or blood products, and patients on dialysis are a high-risk group for hepatitis C infection.

What are the indicators for viral hepatitis testing?

Viral hepatitis can be confirmed for infection through tests such as hepatitis B "two and a half pairs," hepatitis A antibodies, hepatitis C antibodies, and hepatitis E antibodies. By using the hepatitis B "two and a half pairs" test to look for the hepatitis B surface antigen, if the surface antigen is positive, it indicates infection with the hepatitis B virus. The hepatitis A antibody test primarily assesses for hepatitis A antibody IGM; if this is positive, it suggests an active infection. Through the hepatitis C antibody test, if positive, further testing for hepatitis C virus RNA can be conducted. The hepatitis E antibody test mainly looks at hepatitis E antibody IGM, and the interpretation should be based on the specific circumstances.

Symptoms of viral hepatitis

The clinical symptoms of viral hepatitis are mainly related to liver function. Generally, there are no obvious symptoms when liver function is normal or mildly abnormal. However, when liver function becomes significantly abnormal, symptoms such as fatigue, aversion to oil, nausea, abdominal distension, and poor appetite may occur. Different types of viral hepatitis have different prognoses and severity of illness. Treatment should be tailored to the actual situation, including liver protection, enzyme reduction, and addressing the cause through comprehensive treatment.

What are the types of viral hepatitis?

Common types of viral hepatitis include Hepatitis A, Hepatitis B, Hepatitis C, Hepatitis D, and Hepatitis E, as well as Hepatitis G. Infections by the Epstein-Barr virus and cytomegalovirus can also potentially cause liver damage. Of course, there are other related viral infections that can lead to liver damage and can be classified as viral hepatitis. Different types of viral hepatitis have different transmission routes and methods, and their prognosis and outcomes vary. Appropriate measures should be taken based on the specific circumstances.
