[Epidemiology of viral hepatitis B in the Iasi County in the interval 1990-2005]. / Aspecte din epidemiologia hepatitei virale B, în judetul Iasi, în perioada 1990-2005.

ABSTRACT

Viral hepatitis and especially hepatitis B (HVB) continue to represent major health problems. In Romania, the morbidity from HVB is still 3 to 5 times higher than in Western Europe and North America. In the Iasi County, the effectiveness of the preventive measures is proven by a curve of morbidity values close to or even below those recorded at national level. As a result of the preventive interventions, in the interval 1996-2005, the morbidity from HVB was lower in all age groups as compared to the interval 1990-1995. The significant decrease in morbidity following the introduction of a vaccination program and the preservation of a constantly descending trend reflect the favourable change in the epidemiological process of HVB.
