Abstract

A total of 3,508 of hepatitis B cases (including 152 cases of mixed HBV and HCV infections) were reported in Poland in 1999. For the first time since 1979, when registration has began, the incidence decreased below 10.0 and was 9.1 per 100,000. The program of eradication of hepatitis B in Poland has been introduced in 1993 and since then the fourfold decrease in number of hepatitis B cases has been noticed. During the past 7 years there has been a steady decline in hepatitis B incidence. In 1997 the incidence decreased 23% as compared to 1996, followed by 16.8% decrease in 1998 and 13.9% in 1999; the marked differences in incidence in particular voivodeships have been observed. The overall rate of hospitalized hepatitis B cases in Poland reached 98.1%. A total of 25 cases of hepatitis B (rate 1.2 per 100,000) occurred among children under 4 years of age, who should be vaccinated. Among children aged 5-9 years, of which many could not be vaccinated, the incidence rate was 6 times higher, ranging from 4.9 per 100,000 in girls to 9.8 per 100,000 in boys. The increase of incidence from 5.3 to 9.2 was observed in young people (14-24 years old). Data from the study of serological markers of hepatitis B, conducted among 4,500 health care workers during 1998-2000, have indicated that about 22% of health care workers have been infected with HBV (in 21% of persons anti-HBc and in 1% anti-HBc together with HBsAg were detected).
