Background: In China, although quite a few bold programmes have been made for
HIV/AIDS, the epidemic has still shown an increasing trend.
Objectives: The study was aimed to investigate the characteristics of new HIV/AIDS and the major
factors of false positives (FP) for HIV testing.
Methods: A retrospective review was performed in a teaching hospital in Xi’an between 2013 and
2018. The overall characteristics and trends of new HIV/AIDS were described. Moreover, the major
factors of FP were determined by the Pareto analysis.
Results: A total of 469 new HIV/AIDS were diagnosed, with an increasing prevalence of the new
HIV/AIDS from 0.0626% (41/65503) in 2013 to 0.0827% (115/139046) in 2018. Of them, the majority
occurred in the males (88.50%), people aged 21-50 years (76.97%), migrants (60.98%), and
sexual contact route (88.70%). There was a rapid increase in the annual number of new HIV/AIDS
and increasing trends in groups of young individuals, students, and homosexual mode; however, a
downward trend in the percentage of injecting drug use was also observed. Over 50 years old and
patients from oncology, obstetrics, hepatobiliary surgery, nephrology, cardiology, and infectious
disease constituted the major factors of FP.
Conclusion: The HIV/AIDS epidemic in Xi’an is still evolving, therefore, effective strategies, appropriate
education and scaling up HIV testing should be developed. In addition, old adults and specific
departments were associated with FP.
