RESUMO
Prevalence level of HIV markers among blood and blood coMponent donors in European region of WHO increased from 8.3 to 10.3 positive cases per: 100,000 donations diring 2001-2006. In Ukraine from 2.1 to 112.3 positive cases per 100,000 donations in 2012. In 2010 and .2012 prevalence level of blood borne infections among Ukrainian donors was the following: HIV infection--112.3 positive cases per 100,000 donations; HCV--1498.1 cases and 1207.7 cases; HBsAg (hepatitis B surface antigen)--690.4 and 546.6 and antibodies to Tr. Pallidum--747 seropositive cases per 100,000 and 672.5 respectively. Specific weight of truly positive donations for HIV varied on test systems of different manufactures from 28.3% to 58.3% in 2010, from 12.2% to 61.8% in 2011 and from 20.7% to 63% in 2012. Significant fluctuation of results of confirmatory tests and high prevalence of HIV and HCV markers among Ukrainian donors displays a tendency to HIV prevalence which requires to define screening strategy of donated blood taking into consideration epidemiological studies and available state resources.
