The frequency of occurrence anti-HAV antibodies to health employees – own observations.

Introduction: In the years 1997-2016, Poland was counted among the countries with a low and very low endemicity of hepatitis A. Based on the epidemiological data from NIZP–PZH (National Institute of Public Health - National Institute of Hygiene), since 2017, an increase in the incidence of hepatitis A has been observed in Poland. Considering the low number of cases by 2016 and a high percentage of seronegative persons, an increased risk of HAV infections should be expected.
