Viral surface antigen positive), 40% of these
Viral hepatitis is the liver inflammation caused by several viruses; the most common forms are A, B and C. Hepatitis B virus (HBV) is a DNA blood-borne virus that belongs to the Hepadnaviridae family and it is considered to be one of the major causes for the infectious-disease deaths worldwide.(1)The routes of HBV transmission are mainly through contaminated blood and blood products, contaminated body fluids, sexual contact and contaminated needles. (2)Globally, HBV prevalence has been estimated to be around 240 million people living with hepatitis B viral infection (defined as hepatitis B surface antigen positive), 40% of these patients may progress to cirrhosis, liver failure and hepatocellular carcinoma. (3)The World Health Organization (WHO) has adopted a new strategy for HBV elimination by 2030; the main target is to decrease the incidence of newly diagnosed infections by 90% and HBV-related deaths by 65% and to Increase the coverage of HBV testing and treatment. (4)Hepatitis B viral infection is thought to be a major public health challenge in Egypt and Africa and up to this moment there is still a little information about its epidemiology.
(1)The prevalence of hepatitis B viral infection has huge differences among populations in different regions.(5,6) In the Middle East region, the prevalence of HBV carrier among adults varies from low (5%).(7)The Egypt health issues survey (EHIS 2015) reported that upon testing HBV prevalence in population aged 1-59 they found that only 1% of this population tested +ve for HBsAg (surface antigen), indicating active infection.
