OSPINA, Sigifredo et al. Seroprevalence of the hepatitis A virus in children from 1 to 15 years old in a university hospital. Infect. [online]. 2011, vol.15, n.1, pp.8-13. ISSN 0123-9392.
Introduction: Hepatitis A is an infectious disease caused by a non-encapsulated RNA virus of the Picornaviridae family, classified as Hepatovirus. It is transmitted by a fecal-oral route, either from person to person or in common source epidemics. Objective: The aim of this study was to estimate the seroprevalence of IgG antibodies against the hepatitis A virus in children aged 1-15 years, treated in a university hospital as part of a national collaborative study. Methods: A descriptive study was performed between June and November 2007. The antibody titers were detected by means of a Microparticle Capture Enzyme Immunoassay. A survey to identify risk factors was conducted for each participant, with additional variables under study. Results: We studied 422 children. The overall prevalence of antibodies against hepatitis A was 29.1%, with 37.1% in the group of 5 to 9 years of age, 36.1% for 10 to 15, and 13.8% for 1 to 4. The highest proportion of antibody prevalence was found in children of the lowest socioeconomic status, 44.2% for the stratum 1 and 27.9% for the stratum 2. Conclusion: The seroprevalence to hepatitis A virus was lower in children with less than five years of age, which is an indication of a transition of the epidemiological profile to an intermediate one. The prevalence was higher in children of low socioeconomic levels, which may be related to overcrowding and poor hygiene practices
