Viral Hepatitis: Classification, Symptoms And Treatment
Viral hepatitis is a disease caused by a virus and is an infectious disease. Most people only find out when the disease has advanced to the advanced stage because in the early stages of hepatitis there are no obvious symptoms. There are 6 types of viruses that cause hepatitis, namely A, B, C, D, E, G. Each type has different properties and potential to cause disease, so the symptoms and treatments are quite diverse.
What is viral hepatitis?
Viral hepatitis is a condition where the virus is invaded by the virus and causes liver cells to become inflamed and damaged. Viral hepatitis can disrupt the detox process, store vitamins and produce hormones of the liver. Complications of hepatitis are liver failure, cirrhosis, liver cancer .
Types of viral hepatitis
Since 1973 the hepatitis A virus was discovered, spread by eating and drinking due to contaminated food and water. Vaccines are now available to prevent hepatitis A. Hepatitis A is benign, does not turn into chronic and can be completely cured but can be re-infected.
Hepatitis is caused by many viruses
The hepatitis B virus has a very small structure, when infected, the patient's liver will swell, which can cause serious damage. Hepatitis B becomes chronic leading to complications such as liver scarring, cirrhosis, hepatocellular carcinoma. 20 years ago, there was a vaccine against the disease, the prevention effect was up to 95%. So far there is no way to completely cure hepatitis B
Hepatitis C virus has been found since 1989 with genetic diversity but so far there is no vaccine to prevent this disease because there is no suitable and diverse cell culture system of the genotype.
Despite being cured, the body can still get re-infected with hepatitis C. And up to 80% of people with chronic hepatitis C will have it.
This is an incomplete virus (only the shellless nucleus) was discovered in 1977. Therefore it cannot independently cause disease but must be co-infected or superinfected with hepatitis B to be able to cause disease. Currently there is a vaccine to prevent hepatitis D.
The course is benign, completely cured and not reinfected. If pregnant women are infected with hepatitis E, they are at a higher risk of becoming malignant hepatitis and have a high mortality rate. The hepatitis E virus has been found since 1991, so far there has been no vaccination vaccine in our country.
25% of hepatitis G is similar to hepatitis C but its role is not clear. More than 70% of people with this disease do not have clinical manifestations.

- Clinical diagnosis through symptoms: hepatomegaly, softness, pain in the area of the liver, loose stools, dark yellow urine ..
Subclinical diagnosis (laboratory)
- Elevated liver enzymes (SGOT, SGPT), in which SGPT is usually higher than SGOT
- Blood bilirubin increases
- Diagnostic tests for etiology: HBsAg, anti HCV, anti-HBB IgM ..
Methods of treatment of viral hepatitis
- Hepatitis A: Almost all patients with liver A will recover by abstaining from alcohol and drugs without treatment. And in fact, there is no medicine or cure for hepatitis A yet
Depending on the situation, the doctor may prescribe medication
