Can Men With Hepatitis B Cirrhosis Transmit the Virus?

Hepatitis B cirrhosis in men can potentially be contagious, depending on specific medical conditions and viral markers. Here's a detailed breakdown:

The level of transmission risk depends largely on the patient's surface antigen and HBV-DNA status. If a man tests negative for both hepatitis B surface antigen (HBsAg) and HBV-DNA, it typically means that the virus has been cleared from the body, making transmission extremely unlikely.

In some cases, patients may have a positive surface antigen but undetectable HBV-DNA levels. While this suggests a lower viral load, there may still be a minimal risk of transmission, particularly through direct contact with bodily fluids.

When both HBsAg and HBV-DNA are positive, the person is considered highly contagious. In such cases, the virus is present in blood and other bodily fluids, increasing the likelihood of transmission through needle sticks, open wounds, or sexual contact.

There is ongoing debate about whether hepatitis B can be passed from father to child through sperm. Although mother-to-child transmission is well-documented, the possibility of paternal transmission remains unclear and requires further research.

Understanding these factors is crucial for managing hepatitis B and preventing its spread. Regular testing and consulting with a healthcare professional are recommended for anyone concerned about potential exposure or transmission risks.
