    Article - En anglais


    To evaluate the prevalence of anti-hepatitis A virus (HAV) in an urban population, in order to assess the changing epidemiological pattern of hepatitis A. Subjects : We studied 325 health care workers from Santa Maria Hospital and 201 students of the Medical School of Lisbon.


    The prevalence of anti-HAV was lower in the younger age groups : 29% in the first 3 years of Faculty compared to 46% in the last 3 years, P<0.001.

    The overall prevalence for students was 35%, whereas in health care workers of less than 30 years it was 65%, P<0.001.

    These findings show a declining prevalence of anti-HAV, particularly in younger age groups, when compared with the results obtained in 1983, which showed a prevalence of 85%. Conclusion : The epidemiological pattern of hepatitis A in Lisbon, Portugal, is changing in some urban groups, with prevalences approaching those of more developed countries.
