Prevalence and estimation of hepatitis B and C infections in the WHO European Region: a review of data focusing on the countries outside the European Union and the European Free Trade Association.

Knowledge of hepatitis B and C prevalence, and numbers infected, are important for planning responses. Published HBsAg and anti-HCV prevalences for the 20 WHO European Region countries outside the EU/EFTA were extracted, to complement published data for the EU/EFTA. The general population prevalence of HBsAg (median 3·8%, mean 5·0%, seven countries) ranged from 1·3% (Ukraine) to 13% (Uzbekistan), and anti-HCV (median 2·3%, mean 3·8%, 10 countries) from 0·5% (Serbia, Tajikistan) to 13% (Uzbekistan). People who inject drugs had the highest prevalence of both infections (HBsAg: median 6·8%, mean 8·2%, 13 countries; anti-HCV: median 46%, mean 46%, 17 countries), and prevalence was also elevated in men who have sex with men and sex workers. Simple estimates indicated 13·3 million (1·8%) adults have HBsAg and 15·0 million (2·0%) HCV RNA in the WHO European Region; prevalences were higher outside the EU/EFTA countries. Efforts to prevent, diagnose, and treat these infections need to be maintained and improved.

[An intrahospital outbreak of HIV infection in Elista]. / Vnutribol'nichnaia vspyshka VICh-infektsii v Eliste.

For the first time a nosocomial focus of HIV infection was established. Out of 83,000 inhabitants of the Kalmyck ASSR who underwent planned examination in the course of epidemiological investigation, 65 cases of HIV infection were detected and all of them were traced to the focus of hospital infection (56 children and 9 adults: 1 man and 8 women; of these, 7 women contacted the infection from their infected children in the process of breast feeding). The children were infected during their stay in two hospitals of Elista where they received multiple intravenous and intramuscular injections. The infection spread from the infant department of the regional pediatric hospital to 4 more departments and to the infectious diseases hospital. Transmission of this infection was maintained for several months by the use of nonsterile syringes in parenteral manipulations.
