[Review of current issues of diagnosis and prevention of blood-borne nosocomial viral infections.]

Provision of infection security in transplantology and transfusiology is a challenging and significant problem that depends on the quality of medical donor selection and laboratory diagnosis of the blood collected. At present, a large number of blood-borne viruses are known; nevertheless, in Russia, the list of viral agents to be tested during the examination by the blood service boils down to three ones: HIV, hepatitis C and hepatitis B viruses. The review article demonstrates the need for implementation of additional laboratory tests for the agents of the priority healthcare-associated blood-borne infections (HAI) using a risk-based approach, i.e., on specified sites and in high risk groups. It presents a methodology for determination of a quantitative blood-induced infection residual risk (BIRR) index to be used while evaluating the efficiency of viral security provision in the blood service.
