Abstract
Most of the European Union (EU) and European Economic Area (EEA) is considered a region of very low hepatitis A virus (HAV) endemicity; however, geographical differences exist. We did a systematic review with the aim of describing seroprevalence and susceptibility in the general population or special groups in the EU and EEA. We searched databases and public health national institutes websites for HAV seroprevalence records published between Jan 1, 1975, and June 30, 2014, with no language restrictions. An updated search was done on Aug 10, 2016. We defined seroprevalence profiles (very low, low, and intermediate) as the proportion of the population with age-specific anti-HAV antibodies at age 15 and 30 years, and susceptibility profiles (low, moderate, high, and very high) as the proportion of susceptible individuals at age 30 and 50 years. We included 228 studies from 28 of 31 EU and EEA countries. For the period 2000-14, 24 countries had a very low seroprevalence profile, compared with five in 1975-89. The susceptibility among adults ranged between low and very high and had a geographical gradient, with three countries in the low susceptibility category. Since 1975, EU and EEA countries have shown decreasing seropositivity; however, considerable regional variability exists. The main limitations of this study are that the studies retrieved for analysis might not be representative of all EU and EEA publications about HAV and might have poor national representativeness. A large proportion of EU and EEA residents are now susceptible to HAV infection. Our Review supports the need to reconsider specific prevention and control measures, to further decrease HAV circulation while providing protection against the infection in the EU and EEA, and could be used to inform susceptible travellers visiting EU and EEA countries with different HAV endemicity levels.

Outbreak of hepatitis A in a nursery school. BIOMED RESEARCH INTERNATIONAL 2013; 2013:684908.

Abstract
In a background of very low incidence of hepatitis A HA in the last decade (annual average of 1.8 cases per 100,000 inhabitants) we describe an outbreak of HA which evolved in Mallorca between May and August 2010, whose main focus was a nursery school where more cases were parents and other young relatives of the children of the institution. Thirty-four cases were defined as outbreak cases. Ten were children of the nursery or their siblings and 22 adults (3 staff members of the nursery and 19 relatives; median age 33 years). The first detected cases were children of the same class. There were 2 adults with haematological complications, though not severe. All children, nursery staff members, parents, and siblings of the cases of the first affected class were immediately offered HA vaccination, but only 43.3% eligible individuals accepted it. None of the cases had been vaccinated. The outbreak spread mostly from asymptomatic children to young adults, showing the changes in HA pattern. That is of great concern as the risk of severe illness rises with age. This incident shows the need to implement new HA vaccination policies in outbreak control. This was later carried out.

Abstract
Hepatitis A virus (HAV) remains a public health concern worldwide contributing to significant morbidity in developed and developing countries. This cross-sectional database study estimated the overall HAV seroprevalence and the seroprevalence by gender, age, region and socioeconomic status in Mexico. Between January and October 2010, serum samples collected during the National Health and Nutrition survey (ENSANUT 2006) were obtained from subjects aged 1-95 y. Subjects' gender, age, geographical region and socioeconomic status were extracted from the survey and compiled into a subset database by the Mexican National Institute of Public Health. Anti-HAV antibodies were measured using a chemiluminescent immunoassay. A total of 3658 subjects were included in the according-to-protocol cohort. Overall, the HAV seroprevalence was 84.2%. The HAV seroprevalence rates were similar between females (86.1%) and males (82.2%). The percentage of subjects seropositive for anti-HAV antibodies was highest in adults aged ≥ 20 y (96.9%), followed by adolescents aged 10-19 y (80.1%) and lowest in children aged 1-9 y (45.0%) (p < 0.0001). Regionally, the highest HAV seroprevalence rate was observed in the South (88.8%) followed by Central and Northern Mexico and Mexico City (p = 0.02). The HAV seroprevalence was similar between subjects of high socioeconomic (90.1%) status and of low socioeconomic status (86.6%). This study confirms the intermediate HAV endemicity in Mexico. Cost-effectiveness studies are necessary to evaluate the inclusion of an effective hepatitis A vaccine from a population-based perspective in addition to continuous efforts to improve hygiene and sanitation that have a substantial impact on the disease burden.

Abstract
BACKGROUND Hepatitis A virus (HAV) has a worldwide distribution, although this distribution tends to be uneven among geographical regions and population groups. The prevalence of anti-HAV antibodies in the general population varies widely among countries. In Europe, the seroprevalence of HAV is reported to range from 32% to 88%. OBJECTIVES The aim of this study was to determine the seroprevalence of HAV among the general Croatian population. MATERIALS AND METHODS During a 2-year period (2008-2009), a total of 791 serum samples were tested for the presence of anti-HAV total (IgM+IgG) and anti-HAV IgM antibodies using an automated enzyme-linked fluorescent assay (Mini Vidas; bioMérieux, Marcy l'Etoile, France). RESULTS The overall anti-HAV seroprevalence was 41.6%. The observed difference in the seroprevalence rates among male and female patients was not statistically significant (44% vs. 39.6%, P = 0.218). A marked increase in anti-HAV seropositivity with age was observed (P < 0.001). The seroprevalence did not differ significantly between participants residing in rural regions (45.3%) and those residing in urban regions (40.6%, P = 0.292). CONCLUSIONS Our results corroborate those of seroprevalence studies in other developed countries. More than half of the Croatian population (59.4%) is susceptible to HAV infection. Older age is an important predictor for being anti-HAV positive.

Abstract
INTRODUCTION The objective of this study is to analyze data related to hospitalization, comorbidities, median stays and costs associated with the hospitalization cases of hepatitis A in Spain, during the 2005-2008 periods. METHODS A retrospective study of the characteristics of acute hepatitis A patients admitted to Spanish hospitals was performed using the minimum basic dataset. Costs were calculated using the diagnosis-related groups for the disease. RESULTS The total number of hospitalized patients diagnosed with acute hepatitis A was 2395 (2.66/100,000 inhabitants); 61.5% were diagnosed in men. The highest rate corresponds to the group aged 20-39 years (4.01/100,000 inhabitants). When compared with year 2005 ascending tendencies in hospitalization was found for the year 2008 (incidence rate ratio 1.36 confidence interval 95% 1.32-1.39). Twenty-four deaths (1%) were reported out of the total of hospitalized patients. The median hospital stay was 5 days. An increase of cost from euro 1.272.608 in the year 2005 to euro 2.586.657 in 2008 was observed. Therefore, the total cost derived from these hospitalizations, above the retail price index, has increased by 90%. CONCLUSION The incidence of hospitalized patients diagnosed with acute hepatitis A in Spain has remained stable from 2005 to 2007 and increased significantly in the year 2008. Therefore, a change in the epidemiology of hepatitis A may be taking place in Spain and this disease could become a public problem in the young adult population. It is necessary to conduct a cost-effectiveness study to assess the need for including hepatitis A in the universal immunizations schedule.

Abstract
Hepatitis A is a worldwide vaccine-preventable infection. Recommendation of vaccination depends on the endemicity of the disease. The World Health Organization recommends universal hepatitis A vaccination in intermediate areas; however, there is no need of mass vaccination in high and low endemicity regions. Therefore, most of the countries are using a vaccination policy according to the endemicity characteristic representing the whole of the country. The endemicity of this infection varies due to sanitary and hygiene conditions and socioeconomic differences among the countries and in various regions of the same country. A sample of 1173 persons between the age of 0 and 91 years from nine randomly selected medical centres from five different geographical centres of Turkey were tested for the level of anti-hepatitis A virus (anti-HAV) immunoglobulin-G antibodies using an enzyme-linked immunosorbent assay. The overall prevalence of anti-HAV antibodies was 64.4% (1142/1173). While the rate of sero-positivity was over 80% in the 5-9 age group and more than 90% after 14 years of age in south-eastern and eastern regions, it was lower than 50% at the age of 5-9 years in central and western regions and remains under 80% in those areas. We conclude that the differences observed in HAV sero-positivity among various geographical regions in Turkey support a universal HAV immunization policy for children currently living in regions of intermediate endemicity.
