Abstract:
Objective To provide basic datas for enriching the scientific and reasonable security strategy of blood transfusion in Chongqing ,even for the national use in the future ,we studied the infection status of human parvovirus B19(B19V) among unpaid blood donors and evaluated the prevalence of B19V in Chongqing .Methods B19 IgM and B19 IgG antibody from blood donors were detected by the method of enzyme linked immunosorbent assay .Results Among 1 104 blood samples of blood donors ,the positive rate of B19 IgM was 5 .07% ,and the positive rate of B19 IgG was 36 .68% ,there was a significant difference between them(P<0 .05) .The positive rate of B19 IgM from females was higher than males′(P<0 .05) ,but there was no statistical difference for the positive rate of B19 IgG between different gender(P> 0 .05) .Comparing with various age groups ,There was still no significant difference of the positive rate of B19 IgM among them(P>0 .05) ,but the positive rates of B19 IgG increased with age increasing (P<0 .05) .The different blood types or collection seasons ,and the statistical difference were not established in these two condi‐tions (P>0 .05) .And there was no significant difference for positive rate of B19 IgM between positive samples and negative sam‐ples of HBV ,HCV ,HIV ,the results of B19 IgG also were such(P> 0 .05) .Conclusion Among blood donors in Chongqing ,al‐though there was no screening for B19V ,we still found infections by B19V .So this may illustrated that the risk of blood transfusion by B19V was still existed .
