Intra-familial transmission of hepatitis virus has been a challenging problem both in medicine and public health for many years. Therefore, many studies have been carried out to assess its prevalence and probable routes and mechanisms of transmission. According to studies, the prevalence varies among different settings. Besides, regarding different modes of transmission, blood and sexual contact are common routes. So, many preventive measurements like some barrier contraceptives (i.e condoms…), child vaccination and screening for HBV infection in pregnant women have been taken for many years. However, whether sharing personal hygiene items, household close contact or other unknown paths lead to hepatitis virus infection in a family or not are the matters in question. Hence, conducting more research about it especially prospective studies could help not only health policy makers but also uninfected family members for preventive actions.
