Methods A descriptive statistical analysis was conducted on the HIV testing data reported in Shenzhen during 2016-2020. The chi-square test for trend was used to compare the positive rates of initial screening and confirmatory tests indifferent years, and a P-value of less than 0.05 was considered statistically significant. Results From 2016 to 2020, the number of HIV testing in Shenzhen increased from 1.6450 to 2.0120 million. The positive rate of HIV initial screening among population in Shenzhen decreased from 2.73‰ to 2.42‰. The positive rate of HIV confirmatory test declined from 77.5% in 2016 to 72.8% in2019, but rose to 78.1% in 2020. The positive rates of HIV initial screening in samples from medical institutions, voluntary counseling and testing (VCT), public security and judicial administration organs, HIV-positive relatives and specialinvestigation were 1.71‰, 30.58‰, 9.54‰, 233.98‰ and 24.32‰, respectively, and the positive rates of HIV confirmatory test were 74.6%, 94.1%, 74.6%, 83.5% and 61.1%, respectively. 70.4% of the positive samples in HIV initial screening underwent confirmatory testing, of which the ratio of HIV confirmatory test in medical institutions decreased from 71.3% in 2016 to 55.2% in 2020, and the ratio in public security and judicial administration organs was significantly reduced to 41.4% in 2020. Conclusion HIV testing in medical institutions is the main source of HIV infection and AIDS cases. It is necessary to further promote HIV consultation and testing service in key departments like sexually transmitted disease clinics; meanwhile, we should strengthen HIV active surveillance such as HIV voluntary counseling and testing, special investigation and screening of HIV-positive relativesand enhance coordination and communication among health, public security and judicial administration organs so as to promote the quality and efficiency of testing and information work.
