Can hepatitis B be transmitted between spouses?

Hepatitis B generally refers to chronic viral hepatitis B. Chronic viral hepatitis B is defined as a condition in which hepatitis B virus (HBV) testing remains positive for more than six months, or when the onset date is unclear but clinical manifestations consistent with chronic hepatitis are present. So, can hepatitis B be transmitted between spouses? The following addresses this question.

Can hepatitis B be transmitted between spouses?

Yes, hepatitis B can potentially be transmitted between spouses. Chronic hepatitis B results from infection with the hepatitis B virus (HBV). Individuals with chronic hepatitis B and asymptomatic HBV carriers serve as the primary sources of infection. HBV transmission may occur via mother-to-child transmission, blood transfusions or blood products, percutaneous or mucosal exposure to infected bodily fluids, and sexual contact.

Following HBV infection, disease outcomes and clinical presentations vary significantly depending on viral factors, host immunity, and environmental influences. Therefore, sexual contact represents a substantial route of HBV transmission between spouses.

Thus, if one spouse is diagnosed with hepatitis B or is an asymptomatic HBV carrier, the other spouse should promptly undergo hepatitis B serological testing (the “five-item HBV panel”). If all five markers are negative—indicating no prior infection and absence of protective antibodies—the uninfected partner must receive the hepatitis B vaccine without delay to prevent infection. Spouses should exercise heightened vigilance and preventive measures.

The above outlines whether hepatitis B can be transmitted between spouses. We hope this information is helpful to you.
