Objective To understand the prevalence of syphilis in unpaid blood donors, assess the effectiveness of blood donation and safety consultation strategies, and ensure blood safety. Methods The syphilis antibodies were detected by ELISA and the ELISA positive samples were detected by TPPA. Epidemiological analysis of syphilis positive donors from 2009 to 2013. Results A total of 121 006 cases were detected in 2009-2013. The positive rate of syphilis antibody ELISA was 448, with a positive rate of 0.37%. The positive rate of TPPA was 308 and the positive coincidence rate was 68.8%. There was no significant difference in the positive rates of syphilis between blood donors of different sexes in different years. The positive rates of syphilis in blood donors of different age groups were significantly different. Conclusion The prevalence of syphilis infection in blood donors in Shaoxing is at a low level, and the strategies for blood donation recruitment and safety consultation are effective and need to be maintained.
