OBJECTIVE: Transfusion-transmissible infections (TTIs) are severe threats to blood safety and public health. A retrospective study of blood donor records from 2015 to 2019 in Shiyan, China, was conducted.
METHODS: TTI prevalence was analyzed using ELISA, RT-PCR, and demographic data. Chi-square test and logistic regression were used to analyze incidence trends and associations for HIV, hepatitis B virus (HBV), hepatitis C virus (HCV), and Treponema pallidum (T. pallidum).
RESULTS: Of 230,225 donors, 2,453 (1.07 %) were TTI-positive. HIV, HBV, HCV, syphilis rates were 0.08 %, 0.40 %, 0.19 %, 0.40 %. Significant decreases in HBV, HCV, T. pallidum from 2015 to 2019; HIV decreased from 2018 to 2019. The prevalence is higher among women aged 35-60, farmers with T. pallidum and young female students with HIV infection.
CONCLUSIONS: Despite the relatively low prevalence of TTIs at present, awareness of TTIs and ongoing blood screening are still needed to ensure blood safety.
