“…However, it is very low compared with the range of Southeast Asia (20%-30%) which results in high rates of prenatal HBV transmission. 21 It is obvious that 58% of chronic asymptomatic carriers pregnant women in our study show evidence of high infectivity where they are positive for HBe Ag which is known to be responsible for infectivity. Probably 90% of these mothers could be expected to transmit HBV to their infants and 85%-90% of them will become chronic carriers.…”

“…The rate was as high as 25-30% in many Pacific island nations in the prevaccination era. 11,12 In the WPR, there are an estimated 160 million people with chronic HBV infections and more than 360 000 HBVrelated deaths occur annually. 5,11,13 This is higher than the number of deaths from tuberculosis, which was 291 240 in 2006.…”

In 2005, the WHO Western Pacific Region adopted the hepatitis B control goal of reducing the hepatitis B surface antigen seroprevalence in children at least 5 years of age to less than 2% by 2012. Universal infant immunization with three doses of hepatitis B vaccine, including a timely birth dose, is the key recommended strategy. Measuring seroprevalence in children at least 5 years of age takes into account the period when the risk of acquiring a chronic infection is highest and provides an indicator that can be monitored in the short term, within 5 years of vaccine introduction, and which correlates strongly with the long-term consequences of hepatitis B.A time-bound supranational hepatitis B control goal was chosen to create a sense of political urgency for strengthening routine immunization services and improving access to delivery care as well as providing resources for hepatitis B vaccination. Consequently, the programme strategies selected are not stand-alone but also contribute to strengthening health systems. Independent certification of achievement of the control goal, hitherto used mainly for eradication goals, is planned for all countries.Early assessment showed that adopting the regional goal led to greater political commitment, with reduced inequalities in hepatitis B vaccination between and within countries. Previous declining trends in routine immunization coverage also show signs of reversal and there is major progress in providing timely birth doses. A similar approach may be relevant to countries in Africa and South Asia, that have a high hepatitis B disease burden faltering routine immunization and poor access to skilled delivery care.Une traduction en français de ce résumé figure à la fin de l'article.

Background: Hepatitis B Virus (HBV) infection remains a public health and health care issue in Iran. Since the data on its outbreak is required for effectual policies, this epidemiological study was performed on population from Neyshabur, where there has been no former epidemiological information. Objectives: This study aimed at investigating the epidemiology of hepatitis B surface antigen among subjects from Neyshabur, from year 2011 to 2015. Methods: The researchers established this study from data collected from a surveillance system. Screening tests were carried out by the Chemioluminsance method. Age, gender, referral year and month were the investigated variables. Data were analyzed by the SPSS-20 software. Results: The prevalence of HBsAg in Neyshabur was 4.11%. In the age group of more than 40 years (1.87%) and females (2.2%) had significantly (P < 0.0001) higher rates of HBV seropositivity. Also the year 2011 (5.26%) and the month of July (0.48%) had the highest prevalence. Conclusions: Hepatitis B Virus (HBV) infection rate was seemingly high in Neyshabur, even higher than other parts of Iran. An immunization program should be continued progressively for high-risk areas, especially the Neyshabur city of Iran.
