Viral hepatitis refers to liver function damage caused by viruses such as hepatitis A, B, C, D, E, non-A, and non-E, and is a type of infectious hepatitis. This infectious hepatitis is collectively known as viral hepatitis, which mainly manifests as abnormal liver function, elevated transaminases, and abnormal bilirubin levels. To determine the specific cause of viral hepatitis, it is necessary to complete hepatitis antibody tests. Only after clarifying the hepatitis antibody tests can it be determined which virus caused the liver function abnormalities. Therefore, viral hepatitis is a general term that also includes various types and causes. To further clarify, additional testing is required. Only through further testing can the cause be clearly identified for better treatment.

Dietary care for viral hepatitis

Patients with viral hepatitis generally have noticeable gastrointestinal discomfort symptoms, such as fatigue, poor appetite, nausea, vomiting, and bloating after eating. Therefore, it is advisable for patients with viral hepatitis to maintain a low-fat, light diet. Vegetables and fruits are fine to consume, but greasy foods, such as meat, are not recommended. If meat is desired, white meats like fish are preferable, while red meats are advised against. If viral hepatitis is accompanied by other diseases such as hepatic encephalopathy, it is recommended not to consume soy products and eggs. Patients with viral hepatitis often have concurrent gallbladder diseases, so consuming eggs or greasy foods may exacerbate symptoms and cause significant upper abdominal discomfort.

Is viral hepatitis airborne?

Viral hepatitis cannot be transmitted through the air, and different types of viral hepatitis are transmitted through different routes and have different clinical symptoms. The characteristics of the disease vary; for example, hepatitis A and hepatitis E are primarily transmitted through the digestive tract, via the fecal-oral route. This typically occurs after consuming food or water contaminated with hepatitis A or E virus. Hepatitis B and hepatitis C viruses are mainly transmitted through blood, sexual contact, and from mother to child, with mother-to-child transmission being the most significant route.

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.

Treatment of viral hepatitis

Once viral hepatitis occurs, the liver function is obviously abnormal. Patients may have significant discomfort symptoms such as fatigue, poor appetite, nausea, vomiting, and bloating after eating. Therefore, the treatment of patients with viral hepatitis mainly consists of two aspects. The first aspect is bed rest combined with a light, low-fat diet. The second aspect is pharmacological treatment. For patients with significantly abnormal liver function, medications that protect the liver and reduce enzyme levels are needed. If significant jaundice occurs, medications to reduce jaundice are required. Additionally, if the viral hepatitis is caused by hepatitis B or C, antiviral medications might be necessary. Only through active antiviral treatment can the damage to the liver by the virus be reduced, and thus better recovery of the patients can be achieved.

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.
