    Abstract:
    The authors evaluated the incidence of infection by hepatitis A virus (HAV) in a paediatric population through a seroepidemiological investigation in a group of 278 children (0-12 years old), apparently healthy. The determination of anti-HAV antibodies was carried out by ELISA-test. Of the 287 examined sera, 27 cases turned out HAV positive antibodies (9.7%), with the following distribution, according to the groups of age: 0-3 months: 2 of 6 children were positive (mother's antibodies); 3 months-2 years: 6 of 112 (5.35%); 2-6 years: 10 of 93 (10.75%); 6-12 years: 11 of 67 (16.41%). With regard to distribution of anti-HAV antibodies by sex, 23 (15.03%) males of 153 resulted positive, whereas 4 (3.2%) females of 125 resulted positive. The decline of HAV infection in the paediatric age involves a possible shift of the risk to the adult age. It's advisable that the vaccination against hepatitis A in first period should be reserved for the subjects at risk and later both for unweaned and children in order to eradicate the infection.
