IDAHS, a recently-defined term in clinical hepatology, stands for incidentally-detected asymptomatic HBsAg-positive subjects. Million of IDAHS are prevailing in the world. Even, higher percentage of IDAHS is present in developing countries of Asia and Africa, where poorly-developed health care delivery system is incapable of detecting HBV infection at different levels. These patients have been exposed recently as HBV-infected because of better surveillance against HBV. People undertake HBsAg checking before vaccination or during pregnancy. IDAHS patients, although remain asymptomatic during first diagnosis, they are not free from liver damages. Recent studies have shown evidences of severe liver damages in IDAHS patients from different countries. In fact, IDAHS represent a living and permanent source of HBV infection and proper diagnosis of these patients are needed for containment of HBV infection. The present section of this book has provided a detailed outline about IDAHS and their characteristics features. Also, possible management strategies of these patients have been provided. In fact, most of the text book about liver diseases has not addressed about IDAHS before.
