title: [Epidemiological characterisation of acute and chronic hepatitis B in Uzbekistan].
abstract: The epidemiological survey of 126 foci with patients having acute hepatitis B (AHB) and 120 foci with patients having chronic hepatitis B (CHB) was conducted. The observation of the susceptible members of the family showed that a significantly higher level of infection was found in persons having contacts with CHB patients (44.4 +/- 2.3%) in comparison with the members of the families of AHB patients (33.2 +/- 2.3%). The study revealed that children under 14 years were actively involved into the epidemic process; in these children the highest levels of infection were observed in the families of AHB patients (40.2 +/- 3.7%) and CHB patients (57.1 +/- 3.5%). High detection rate of HbsAg were noted in brothers and sisters in the foci of AHB (42.3 +/- 6.4%) and the foci of CHB (52.3 +/- 5.4%), also in parents: 32.4 +/- 5.2% and 46.5 +/- 4.2%, in children: 28.8 +/- 3.4% and 35.6 +/- 3.6% respectively.
