Abstract
The mass immigration of Ethiopian Jews to Israel began in the 1980s. For most of these immigrants this was a time of sharp transition from a village life with very basic living conditions, in most cases without a regular supply of water, electricity, or healthcare services, to a modern Western urban society. The aim of this review was to search the medical literature on the characteristics of infectious diseases that are typical in Ethiopian immigrants (EI), using relevant keywords. There has been success in coping with diseases among EI, that are rare although recognized in Israel, in terms of screening and early identification. TB was common in Ethiopia over all the years of immigration to Israel. In contrast, HIV appeared in EI from 1999 when they had long stayovers in transition camps in Gondar and Addis Ababa where there was a high risk of infection with sexually transmitted diseases. There were often delays in diagnosing 'exotic' diseases that are endemic in Africa, but not well known in Israel, such as Onchocerciasis, Schistosomiasis, Strongyloidiasis, and Bartonella endocarditis, which cause severe morbidity and mortality among EI. We describe the effect on general morbidity in Israel, and how the healthcare services coped with these diseases, including obstacles, and failures and successes. In light of the ongoing immigration of African refugees to the United States and Europe, the Israeli experience can be of value to healthcare policy makers in developing strategies for the effective management by medical staff treating these immigrants.

Velan B, Yadgar Y. On the implications of desexualizing vaccines against sexually transmitted diseases: health policy challenges in a multicultural society. Isr J Health Policy Res 2017; 6:30. [PMID: 28666469 PMCID: PMC5493887 DOI: 10.1186/s13584-017-0153-4] [Citation(s) in RCA: 16] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/13/2016] [Accepted: 05/12/2017] [Indexed: 12/16/2022] Open
Abstract
Two vaccines against sexually transmitted infections are included in many national vaccination programs: Hepatitis B Virus (HBV) vaccine and Human Papilloma Virus (HPV) vaccine. The trajectories of the implementation of these two programs were marked by differences in the way the sexual context of risk was communicated to the public. These trajectories fluctuated between full accounts of the sexual nature of the infection and attempts to desexualize the vaccines. Vaccine desexualization can be achieved by withholding information of sexual context, blurring information, and distancing the age of vaccination from the age of sexual debut. Desexualization may be advantageous in promoting public health and personal health of people who believe that HPV vaccination leads to increased promiscuity, people who believe that protection against STD is not relevant to their children, and people who are not comfortable discussing the sexuality of their children. On the other hand, desexualizing may be disadvantageous for children to parents who tend to express passiveness towards vaccination, parents who attribute importance to sex education, and teenagers with homosexual orientations. The ethical analysis of vaccine desexualization reveals a complex interplay of considerations related to utility, causation of harm, duty of transparency, right to know, and right not to know. This analysis suggests that the moral merits of applying desexualization are questionable. Lastly, a sociopolitical consideration of the matter, suggests that decisions on vaccine desexualization can have implications on the interrelationships between various social groups and subgroups composing a certain population, and may highlight intercultural schisms. All this indicates that shaping the sexual framework of vaccination programs bears implications far beyond the practical considerations of vaccine promotion.

Abstract
BACKGROUND The existing seroepidemiological data on viral hepatitis in Ethiopia showed a wide variation in prevalence pattern and the clinical and public health burden have been underestimated. The aim of this systematic review and meta-analysis was to provide a clear and comprehensive estimation of viral hepatitis epidemiology and the potential clinical burdens in Ethiopia. METHODS A comprehensive literature search was carried out from five decades (1968-2015) published studies from biomedical databases; PubMed, Google scholar, Medline and Web of Science. RESULTS The overall pooled prevalence of hepatitis B virus (HBV) was 7.4% (95%CI: 6.5-8.4). The pooled prevalence among subgroups showed 5.2% (95%CI: 3.7-7.4) in human immunodeficiency virus (HIV) infected individuals, 8.0% (95%CI: 5.9-10.7) in community based studies, 8.4% (95%CI: 5.4-12.7) in blood donors, 11.0% (95%CI: 7.5-15.9) in immigrants and 6.9% (95%CI: 5.6-8.5) in other groups. Among study parameters considered during meta-regression analysis, only study years were associated with a decreasing HBV prevalence rate over time. The overall pooled prevalence of anti-hepatitis C virus antibody (anti-HCV) was 3.1% (95%CI: 2.2-4.4). Unlike HBV, the anti-HCV prevalence in HIV infected individuals was higher (5.5%, 95%CI: 3.8-7.8%, p = 0.01) than the prevalence observed in the other subgroup of study population. Although relatively few data were available, hepatitis virus A (HAV), D (HDV) and E (HEV) were also circulated in Ethiopia. CONCLUSIONS This review indicates that all types of viral hepatitis origins are endemic in Ethiopia. Adapting a recommended diagnostic and treatment algorithm of viral hepatitis in the routine healthcare systems and implementing prevention and control policies in the general population needs an urgent attention.

Abstract
BACKGROUND The household transmission of hepatitis B virus (HBV) is a major health problem. The prevalence rate of this infection is reported about 11% to 57% among family members of HBsAg carriers. OBJECTIVES This study was conducted to evaluate serological determinants of chronic hepatitis B infection, especially HBsAg positivity, among family members of asymptomatic HBsAg positive carriers in Zahedan (Southeast of Iran). PATIENTS AND METHODS In a cross-sectional study, data were collected from the total number of 454 HBsAg positive cases and 1817 members of their family by trained interviewers and a validated questionnaire. In addition, blood samples were obtained and titrated to detect serologic markers of hepatitis B. All subjects were recruited following informed consent to the study. RESULTS In total, 454 chronic HBsAg carriers (66% male) with mean age of 36 ± 10 years and 1817 of their family members were included in the study. The prevalence rate of HBsAg and HBcAb positivity among household members were 19.3% (n = 351) and 51% (n = 573), respectively. The frequency of HBV markers was different by age groups. The highest prevalence rate of HBsAg (34.9%) and HBcAb (31.9%) positivity were found in the age group of 21-30 years old. Importantly, the mothers of index cases had the highest prevalence of HBsAg positivity compared to their spouses who had the lowest proportion (53.2% vs. 8.4%, P < 0.001). CONCLUSIONS In family members, HBsAg positivity was four times greater than the general indigenous population. Considering the importance of close contacts for transmission, it was more prevalent in mothers of index cases compared to their spouses, suggesting more efficient mother-to-child than sexually transmission of HBV. It was also more prevalent in those having a history of hepatitis B in their maternal family compared to those with paternal one, probably due to more efficient transmission from infected mothers to children. The lower prevalence of HBsAg positivity in lower age groups could be attributed to vaccination of Iranian infants since 1993 and the screening of HBsAg positive mothers during the last two decades.

Abstract
In worst cases, chronic hepatitis B ultimately leads to primary liver cancer. Populations the more at risk to develop hepatocellular carcinoma (HCC), i.e. patients infected perinatally, reside essentially in Asia. A quarter of century after its introduction in medical practice, data coming from Eastern Asia demonstrate a strong impact of the vaccine on HCC incidence. Strikingly, universal immunization of Taiwanese newborns reduced fourfold pediatric HCC incidence. However, residual cases still appear though among children infected at birth by HBe antigen-carrying mothers. Epidemiologic models indicate that the continuation of universal vaccination policy will reduce chronic hepatitis B endemicity 50-fold in three generations. Recently, mutant forms of HBV potentially escaping to vaccine appeared as a potential consequence of large-scale vaccination. Finally, lack of early immunization of newborns in developing countries still represents a major limitation to the progresses against liver cancer.

Abstract
We report an evaluation of the Israeli national immunization programme for hepatitis B in the Haifa subdistrict. We used a convenience sample of blood tests reported positive for HBsAg over a 6-year period from children who were born after routine immunization began in 1992. We identified 11 children with presumed chronic hepatitis B virus infection who were residents of the Haifa subdistrict, three of whom were born in Israel. All three were immunized at the appropriate age and are thus considered vaccination failures rather than failure to vaccinate. The remaining eight were born abroad, had emigrated to Israel as children and were not immunized at birth. We estimate the rate of chronic hepatitis B virus infection for children born since 1998 to be 0.24/10,000 births. For all children resident in the subdistrict under the age of 12 years, the period prevalence is estimated to be 1.26/10,000. The rate of chronic infection in children younger than 12 years was significantly less than that of older cohorts and less than that of historical controls before the start of immunization. Although the reported rates are probable underestimates of actual rates, the fact that they are based on testing carried out in clinical settings increases the likelihood of positive findings and thus reduces the degree of error. The fact that most young carriers are foreign born points to the importance of timely catch-up programmes. In countries with low and intermediate rates of chronic infection, serosurveys of immunized children need to be large and are therefore costly. Monitoring HBsAg positive tests from routine testing carried out in clinical settings is an inexpensive way to monitor chronic infection rates.

Abstract
Hepatitis B virus (HBV) infection is a worldwide health problem. The aim of the present study was not only to determine the prevalence of HBsAg in children of HBV-infected parents but also to identify all HBSAg-positive family members to protect as many children, in the present and future, as possible. The study was carried out with the participation of 2113 family members (1205 children, 453 mothers, and 455 fathers) at Sivas SSK Hospital, Turkey. They were screened for HBV markers using standard enzyme immunoassay between September 2001 and March 2005. The prevalence of any HBV markers and HBsAg among family members of index cases was 50.5% and 30.5% respectively. HBsAg carrier rate was higher among fathers (61%) than mothers (47%), (P<0.05). The children of mother index cases had higher rates of HBsAg compared with the children of father index cases (P<0.01). Our results suggest that intra-familial childhood horizontal transmission (especially mother-to-child) is important for HBV transmission in the Turkish community, and highlights the need for screening of adult siblings and mothers of adult HBsAg carriers in addition to their spouses and children.

Abstract
OBJECTIVE No study has investigated the intrafamilial spread of hepatitis B virus (HBV) in Greece. We conducted a 9-year prospective study to determine the rate of HBV spread in family members when a member is identified as an HBV carrier, the possible routes and risk factors for transmission of HBV and the family members with the highest risk of infection according to kinship degrees. METHODS A total of 387 family members of 166 hepatitis B surface antigen (HBsAg) carriers were investigated for the detection of HBV infection markers using standard enzyme immunoassays; 6.696 blood donors from the same area were used as controls. RESULTS Serological markers of past or current HBV infection were detected significantly more frequently among family members of HBsAg carriers (23.2 and 15.8%, respectively) compared with blood donors (14.1 and 0.85%, respectively). The prevalence of the above markers was higher among siblings, husbands and parents of the carriers. Offspring of the female index cases had higher rates of current or past infection. HBV infection markers were significantly increased in family members who reported common use of syringes (P<0.001), birth in rural areas (P<0.001) and a low level of education (P<0.001). CONCLUSIONS We demonstrated a high risk of HBV transmission among family members of HBsAg carriers, which was associated with special risk factors for contracting HBV. Our findings indicate the need for strict adherence to the universal guidelines of vaccination against HBV and also the need for an immediate investigation of other potentially infected relatives among family members of HBsAg carriers.

Abstract
AIM: To determine the possible routes of intrafamilial transmission pattern in pediatric cases of chronic hepatitis B virus (HBV) infection.
METHODS: In this descriptive retrospective study, 302 children with chronic HBV infection from 251 families and their parents attending the Social Security Children’s Hospital and Doctor Sami Ulus Children’s Hopsital in Ankara between December 1998 and May 2000, were enrolled in. Screenings and diagnosis of chronic HBV infections were established according to the Consensus 2000.
RESULTS: In the studied 302 children with chronic HBV infection, mothers of 38% and fathers of 23% were HBsAg positive. The HBsAg positivity in at least two siblings of the same family was 61% when both parents were HBsAg positive.
CONCLUSION: It is well known that horizontal transmission is quite common in countries where Hepatitis B Virus is moderately endemic. To our best knowledge, this is the largest series observed regarding the horizontal transmission in pediatric chronic HBV infection in Turkey. It is necessary to expand the preventive programs to target not only the newborn period but also all stages of childhood.

Abstract
The Epidemiology of hepatitis B virus (HBV) infection was not precisely known in Gaza. This study investigated the prevalence and risk factors of hepatitis B surface antigen (HBsAg) and simulated the incidence of HBV infection from reported cases of acute hepatitis due to HBV. Blood samples from 810 randomly selected individuals from the general population and from 17,060 blood donors were tested for HBsAg. The prevalence of HBsAg was found to be 3.5% in the general population and 3.8% in blood donors. The simulation model revealed the incidence of HBV infection decreased between 1990 and 1999 from 233 to 56 per 100,000 per annum. The decline started in 1994 and continued afterwards, presumably after the introduction of universal vaccination against HBV and screening blood donors for HBV. However, the authors discuss additional measures to control the transmission of HBV among non-vaccinated cohorts.
