Aim. The objective of this study was to assess dynamics of prevalence of hemotransmissive viral infections (HTVI) markers as mono- or mixed infections in patients admitted to Sklifosovsky Research Institute of Emergency Medicine. Materials and methods. Two hundred thirty-five thousands and seventy patients admitted to the Institute during 1998 — 2007 were screened for the presence of laboratory markers of HTVI (antibodies to HIV, HBsAg, and anti-HCV). Results The long-term screening revealed 27,942 (11.9%) persons positive for laboratory markers, of which 3,099 (11.1%) were positive for >1 marker. It was established that HIV infection as well as viral hepatitis B and C have different level of similarity and ability to coexist. HIV infection was more frequently detected in association with other infections, whereas hepatitis B and C — as monoinfections. Conclusion. Attempt to consider the mutual influence of HTVI on their prevalence from the view of modern concept of microorganisms’ ecology was made. Computation of Jaccard similarity coefficient showed that HIV and HCV have the greatest abilities for coexistence, whereas HIV and HBV — the smallest.
