title: [Hepatitis B virus infections in 2002-2004 in Kujawsko-Pomorskie voivodeship].
abstract: The aim of this study was to review epidemiological status of HBV infections in our province by using new clinical findings. 1836 reported cases of infection HBV were analysed on the basis of available documentation. Diagnosis of the acute, chronic or carrier infection were agreed on the basis of interview and presented clinical, biochemical and immunoserological exponents. 152 cases of acute hepatitis B were reported in analysed period. Among them one child under 9. Remaining cases were new detected chronic infections. The registered morbidity of acute hepatitis B was 58% lower during 3 years. All together 17671 persons were infected HBV in our province and the prevalence was 0, 85%.
  
  
  CONCLUSIONS
  The incidence of acute hepatitis B in 2002-2004 demonstrated a strong tendency for decrease, especially among children under 9. The prevalence of hepatitis B was comparable with european average. The results of our analysis demonstrated that epidemiological status of HBV infections in our province presented in previous publications was incorrect. Statistical data did not differentiate new cases of hepatitis B for acute and chronic which resulted in incorrect outcomes.
