title: [The HIV infection epidemic in the city of Irkutsk under the conditions of drug abuse prevalence].
abstract: The data on the spread of HIV infection in Irkutsk and Irkutsk Province, starting from March 9, 1999, are presented. The simultaneous appearance of 17 multiple morbidity foci of HIV infection, involving 2,227 persons into the epidemic, within the period of 8 months was noted. The age structure of the epidemic process was represented by 1,846 adults aged 18-50 years (83%), 256 adolescents aged 16-17 years (12.9%), 78 children aged 10-15 years (3.5%) and 17 persons of other ages (0.53%). The leading role in the age structure of the epidemic process belonged to young people aged 10-29 years (90.4% of cases). The epidemiological analysis made it possible to establish the fact that the epidemic was linked with the intravenous injection of heroin. The viral contamination of the drug is not excluded also in the process of its preparation for injection.
