Introduction

Chronic hepatitis B carriers are also contagious. Although chronic hepatitis B carriers may not exhibit any symptoms and their liver function may remain normal without apparent damage, the hepatitis B virus is still present in their bodies. Therefore, during contact with a chronic hepatitis B carrier, it is possible to become infected. However, the likelihood of transmission varies among individuals.

Generally speaking, a hepatitis B virus carrier refers to a person carrying the hepatitis B virus. Contact with a chronic hepatitis B carrier may result in transmission, but the probability of infection varies among individuals. Detailed analysis is as follows:

Although chronic hepatitis B carriers might have normal liver function and no symptoms, the hepatitis B virus still exists in their bodies. Therefore, long-term close contact with hepatitis B carriers, such as engaging in sexual activity with a chronic carrier or contacting the infected person's blood, could potentially lead to infection. Additionally, the hepatitis B virus can also be transmitted from mother to child. If a chronic hepatitis B carrier breastfeeds an infant, the infant might also become infected. However, due to individual differences, such as varying immune systems and physical conditions, the probability of infection differs among individuals.

If you are currently concerned about potential hepatitis B infection, it is recommended to undergo appropriate medical tests promptly to determine your status and then take targeted actions based on the results. At the same time, maintaining a regular作息 pattern and a balanced diet in daily life can help reduce the risk of infection.

Is a quantitative hepatitis B surface antigen level of 14,000 IU/mL normal?

The normal reference value for quantitative hepatitis B surface antigen (HBsAg) is generally less than 0.05 IU/mL (reference ranges may vary slightly depending on the testing method). A level of 14,000 IU/mL is far above the upper limit of normal, indicating the presence of hepatitis B virus replication templates in the body. This suggests the individual may be in a state of chronic hepatitis B virus carriage or in the active phase of chronic hepatitis B, and further evaluation is needed to determine the stage of the disease.

Can hepatitis B be transmitted from mother to child?

If a pregnant woman is a chronic hepatitis B virus (HBV) carrier, especially those who are positive for both hepatitis B surface antigen and hepatitis B e-antigen, or have high levels of HBV DNA, her newborn is at high risk of infection when exposed to maternal blood or secretions during delivery. Without any preventive measures, the likelihood of the newborn acquiring hepatitis B virus infection is significantly increased.
