<p>Over the last several decades, a gradual decrease in the incidence of hepatitis A and an increase in the population of non-immune people, especially in the group of young people have been observed in Poland. The aim of this study was to assess of the presence of specific anti-hepatitis A virus IgG class antibodies (anti-HAV IgG) in relation to age among non-vaccinated hepatitis A patients. There were statistically significantly more patients up to 45 years of age with anti-HAV IgG negative results than those over 45 years of age, and the Fi-square correlation coefficient (Φ2) was 0.263 between the analyzed variables. The data analysis shows that the number of people with specific IgG antibodies against hepatitis A increases with age. The risk of hepatitis A infection in people under 45 is high due to widespread seronegativity in this age group.</p>
