What is "Xiao San Yang"? Is "Xiao San Yang" contagious?

"Three positive indicators" refers to an immunological state following hepatitis B virus infection, characterized by positivity for hepatitis B surface antigen, hepatitis B e antibody, and hepatitis B core antibody. The "small three positive" pattern itself does not directly indicate infectivity, but the hepatitis B virus is indeed infectious. If viral replication is active in individuals with the small three positive pattern, they may be infectious. Major transmission routes include blood transmission, mother-to-child transmission, and sexual contact. Patients should ensure adequate rest, avoid excessive fatigue, and maintain healthy lifestyle habits. Treatment should be individualized based on disease status and may include antiviral therapy and liver-protective treatment. Regular follow-up examinations and strict adherence to medical instructions for medication are essential to control the disease progression.
