[The epidemiological trends connected with detection of HIV, HCV, HBV and syphilis markers in blood donors in the years 2006-2009].

UNLABELLED: In the recent years a great progress has been documented in infection prevention. There is more possibilities responsible for infection and its transmission. THE AIM OF THE STUDY: To analyze obtained epidemiological data concerned to detected infection in blood donors in the area of Blood Bank in Katowice in the years 2006-2009. MATERIAL AND METHODS: Statistic calculations taking account of confirmed infections in the years 2006-2009 were analyzed in first-time donors and multiple donors, and for all donors. RESULTS: Tests confirming infection were performed in the IHiT in Warsaw, in RBC in Katowice, confirmation test for syphilis in the RBC in Warsaw. Only the positive confirmed results are taken into account and presented in summary. In first-time donors more frequently the markers of infection: HCV and HBV dozens of times, HIV and syphilis several times were detected. In the group of first-time donors a downward trend was detected in the number of detected infections HBV and HCV In the group of multiple donors the downward trend was documented in the number of detected antibodies associated to syphilis. In the group of multiple donors the number of detected HIV infections has been increased in the years 2008 and 2009. CONCLUSIONS: For monitoring trends of each type of infections, a period of four-years is not sufficiently long. This data needs a further observations.
