OBJECTIVE: To estimate the prevalence of parvovirus B19 infection in Chinese Xiamen area blood donors. METHODS: Blood samples from blood donors were tested for detection of parvovirus B19 DNA and antibody. The direct sequencing and genetype analysis of B19 DNA positive samples were performed. RESULTS: Six out of 10452 samples were B19 DNA positive. The viral loads of the 6 samples were between 3.59×102-1.07×104 IU/ml; the positive rate of B19-IgM was 4.64%(50/1078) and B19-IgG was 16.79%(181/1078). The positive rate of B19-IgG increased with ages, and was not related with the sex. CONCLUSION: The overall prevalence of parvovirus B19 infection in blood donors is lower in Chinese Xiamen area than that in other areas, however, there is still a certain percentage of viremia in donors and the attention should be paid to blood safety in the future work.
