Background: Knowing the immune status against hepatitis A and hepatitis B in children Cochabamba, Bolivia and seroepidemiological association.
Study method: A seroepidemiological study (n = 424) and HBV (n = 436) of HAV in children living in Cochabamba, Bolivia, 2010. A questionnaire was completed by parents for demographics, socioeconomic was performed and housing and blood samples were collected, An ELISA was used to measure antibodies to hepatitis A and B.
Results: As regards Hepatitis A, the overall prevalence 95.4 (95% CI -93.5 to 97.4) were immune. The immunity was higher in children of 5-10 years (97%) and tweens 10-13 years (97.9%), the prevalence of immunity was also higher in subjects whose parents had a low level of education (99, 4 to 99.5%) living in rural areas (98.7%) lived in municipalities with an urban development under (99.1 to 100%), had water delivered home by an oil sisterna (99.4 %) and spoke Quechua at home (99.5%). As to Hepatitis B virus, immunity that presented to the IgG anti-HBs IgG antibodies in the cohort of pre-universal vaccine was 5.8% (95% CI: 3.3 to 8.3%); was higher in men (9.1%), and those living in the suburbs (9.7%). The anti-HBs IgG prevalence among cohort universal post-vaccine was 37.9% (95% CI: 28.5 to 48.1%), and was higher in children who speak Quechua at home (51.0%), those living in the suburbs (53.9%), and those born in 2005 (72.7%). Neither cohort showed differences concerning education of parents. The prevalence of IgG anti-HBc was 1.1% among post-universal vaccine cohort and 1.2% among pre-universal vaccine cohorts (p> 0.05)
