Abstract

Objective To investigate the situation of HIV infection and epidemiological characteristics among voluntary blood donors and pre-transfusion patients in Yuxi prefecture between 2010 and 2021. Methods Date collected with the HIV/AIDS Case Reporting Cards and original record of blood station, HIV antibody positive rate, the demographic characteristics, and epidemiological data of blood donors and pre-transfusion patients, were analyzed accordingly, the related date were statistically analyzed. Results The HIV antibody positive ratio were 5.56‱ and 2.01‱ among pre-transfusion patients and voluntary blood donors （P < 0.001）, showing an downward trend year after year. The HIV-positive detection rate among blood donors aged <25 years was significantly higher at 3.72‰ compared to 1.60‰ for those aged ≥25 years （P = 0.003）. Among HIV-positive blood recipients, the proportion of individuals aged 15-24 years （34.62%） was markedly higher than that among blood donors （1.96%）, whereas no donors were aged ≥50 years compared to 23.53% of recipients （P < 0.001）. Farmers showed a significantly higher HIV detection rate （3.18‰） than students （2.66‰） and other occupations （1.60‰）（P = 0.041）. Similarly, individuals with high school education or below showed a higher detection rate （2.52‰） than those with high school education or above （1.45‰）（P = 0.045）. Among HIV-positive cases, blood donors had a higher proportion of HIV-infected individuals （84.62%） versus AIDS cases （15.38%）, whereas the recipients showed the opposite trend: 41.18% HIV-infected versus 58.82% AIDS cases （P < 0.001）. Conclusion In recent years, the HIV positive detection rate in Yuxi area has shown a downward trend, but the occurrence of HIV in Yuxi area is characterized by youthfulness and low education. Among them, HIV infected individuals through same-sex contact account for an important reason for HIV infection.
