Viral hepatitis is one of the major health concerns worldwide, particularly in Asian countries. Mongolia,
which is located in northern Asia, between Russia and China, is confronting various infectious diseases,
such as viral hepatitis and tuberculosis. As for healthy individuals in Mongolia, the reported prevalence
of hepatitis B surface antigen (HBsAg) was 9 or 10% and the reported prevalence of anti-hepatitis C
virus ranged from 11 to 25%. We reported a markedly high prevalence of hepatitis D virus RNA (83%)
among apparently healthy individuals with HBsAg in Ulaanbaatar. Also due to lack of proper mechanisms
to handle sewerage, disinfection, and lack of clean water supply across the country, hepatitis A is
endemic in Mongolia. Moreover, Mongolia ranked in the high-prevalence zone for hepatitis B, D, and C.
