Abstract: Objective To analyze the characteristics of reactive population in treponema pallidum particle assay (TPPA) among voluntary blood donors (BDs) in Wuhan area. Methods The positive samples by ELISA from voluntary blood donors in Wuhan were collected and confirmed by TPPA from January 2018 to June 2018. Combined with the personal information, the structural characteristics of the population were analyzed. Results Among 78 997 voluntary blood donors, 51 738 were male blood donors and 27 259 female blood donors. 212 cases were confirmed reactive by TPPA, including 119 males and 93 females. The positive rate of syphilis confirmed by TPPA was 0.23% (119/51 738) in male blood donors and 0.34% (93/27 259) in female blood donors, and there was significantly different between gender groups (χ2=8.24, P<0.05). 139 cases were married and 73 unmarried and there was statistical different in marital status groups (χ2=36.13, P<0.05). Among age groups, the highest positive ratio was shown in 36~45 years old with 0.66% and there was statistical different in different age groups (χ2=149.80, P<0.05). Considering education level, the blood donors with technical secondary school degree showed the highest positive rate 0.76% and there was statistical different in education groups (χ2=141.04, P<0.05). Farmers and workers had the highest positive ratio 0.66%, and there was statistical different in occupation groups (χ2=177.10, P<0.05). Conclusion We should focus on the married female blood donors with low education background, who belong to high-risk groups of syphilis. We should do a good job of consultation before blood donation, so as to reduce blood risk and improve blood safety.
