title: [Frequency of occurrence of Hepatitis C virus markers and risk factors among hospital personnel in the Novosibirsk region].
abstract: The occurrence of markers, the genotypic variety of isolates and the profile of risk factors with respect to viral hepatitis C among 629 employees of the Regional Clinical Hospital (RCH) in Novosibirsk and 1,020 employees of the Central District Hospital (CDH) in Iskitim were studied in a cross-sectional investigation. The occurrence of hepatitis C virus (HCV) markers was 5.1% in RCH and 2.2% in CDH. Among the risk factors in the population under study were: the medical history of blood transfusions (TF) with 0 TF, anti-HCV = 2.3%; 1 TF, = 5.7% > 1 TF, = 13.5% (p < 0.001); general anesthesia (GA) with < or = 2 GA, anti-HCV = 2.8%; > 2 GA, = 7.8% (p = 0.002); surgical interventions (SU) with 0 SU, = 1.9%; > 0 SU, = 4.3% (p = 0.012); the intravenous use of drugs (OR = 31.8); age (< or = 25 years, anti-HCV IgG = 8.6% > 25 years, = 4.5%); the number of partners of the opposite sex < or = 4 partners, = 2.4%; > 4 partners, = 6.9%; p < 0.001). The probable risk factors at a working place (pricks and cuts, contamination of mucous membranes with blood and other biological fluids, etc.) proved to be faintly related with the status of HBV infection. HBV isolates detected in the examined persons (35 examinees) were distributed by genotypes as follows: 60% of subtype 1b, 28.6% of subtype 2a/2c, 11.4% of subtype 3a. HBV of genotype 1a was not detected in the examined specimens, while the detection rate of genotype 2a/2c was considerably greater than in specimens obtained in the European and Asian parts of Russia (according to the data reported earlier).
