How is viral hepatitis transmitted?

Viral hepatitis is a contagious disease primarily affecting the liver and caused by various hepatitis viruses. Clinically, it manifests mainly as decreased appetite, nausea, upper abdominal discomfort, hepatic region pain, and fatigue. Below, we address the question of how viral hepatitis is transmitted.

How Is Viral Hepatitis Transmitted?

Viral hepatitis is an infectious disease caused by different hepatitis viruses. The transmission routes and preventive measures vary depending on the specific virus type, as outlined below:

1. Hepatitis A: An acute infectious disease caused by the hepatitis A virus (HAV), transmitted via the fecal-oral route. Prevention focuses primarily on food and water hygiene. The isolation period is three weeks following symptom onset.

2. Hepatitis E: Similar to hepatitis A, it is an acute, self-limiting viral infection with a favorable prognosis. It is primarily transmitted through contaminated water sources.

3. Hepatitis B: The most common form clinically, transmitted mainly through blood and bodily fluids—including mother-to-child vertical transmission, blood transfusions, intravenous drug use, sexual contact, and close personal contact.

4. Hepatitis C: Frequently transmitted via blood transfusion. The hepatitis C virus (HCV) is relatively common and, like HBV, often leads to chronic infection and subsequent chronic hepatitis. Prolonged chronic hepatitis may progress to cirrhosis or hepatocellular carcinoma.

5. Hepatitis D: A defective virus that occurs only in individuals already infected with hepatitis B virus (HBV).

The above outlines the transmission routes of viral hepatitis. We hope this information is helpful to you.
