[Epidemiological situation of hepatitis B in Poland in the years 1979-2004].

Number of cases of hepatitis B in the years 1993-2004 has decreased above 88%. Incidence rate in 2004 in majority voivodships has been similar to average rates in West European countries. The high incidence rate in Poland is now due to high rates in voivodships: Lodzkie, Swietokrzyskie, Dolnoslaskie, Kujawsko-pomorskie as well as of persons in age 20-24 and above 65. The need of analysis of incidence rate in relation to poviats, age of cases with conclusions to eliminate of source, interruption of ways of spreading of infection, and immunization of people especially in high risk groups was discussed and established.
