Objective:
To investigate the characteristics and prevalence of HIV infection among AIDS volunteer counseling and testing ( VCT ) clients in Shangcheng District, Hangzhou City from 2016 to 2019, so as to provide insights into local AIDS control.
Methods:
The demographic features, reasons for counseling and detection of anti-HIV antibody were captured from the VCT clinic of Shangcheng Center for Disease Control and Prevention from 2016 to 2019, and the reasons for counseling and prevalence of HIV infections were analyzed.
Results:
A total of 2 205 clients were included, among whom 1 920 participants ( 87.07% ) were male, 1 094 ( 49.61% ) were at ages of < 30 years, 1 293 ( 58.64% ) were single, and 1 165 ( 52.83% ) had an education level of diploma and above. The common reasons for counseling included a history of homosexual behaviors with men (887 clients, 40.23%), non-commercial irregular heterosexual behaviors ( 661 clients, 29.98% ), commercial heterosexual behaviors ( 308 clients, 13.97% ), HIV-positive spouse/regular sex partners ( 123 clients, 5.58% ), and no high-risk behaviors ( 47 clients, 2.13% ). The positive rate of anti-HIV antibody was 2.95% among the 2 205 clients, and a high positive rate was observed among clients at ages of 50 years and below ( 6.15% ), single clients ( 3.71% ), clients with an education level of primary school and below ( 6.04% ) and clients with HIV-positive spouse/regular sex partners ( 11.38% ).
Conclusions
Single men at ages of less than 30 years and with a high education level are predominant among VCT clients in Shangcheng District, and a history of homosexual behaviors with men is the predominant reason for counseling. There is a relative low prevalence rate of HIV infection among VCT clients in Shangcheng District; however, a high prevalence rate is found among single visitors at ages of 50 years and older, with an education level of primary school and below and HIV-positive spouse/regular sex partners.

To investigate the characteristics of newly reported HIV/AIDS cases aged 15 years and older in Shangcheng District, Hangzhou City from 2006 to 2022, so as to provide the basis for improving AIDS prevention and control strategies.
Methods:
Data of newly reported HIV/AIDS cases aged 15 years and older in Shangcheng District from 2006 to 2022 were collected through HIV/AIDS Comprehensive Control System of Chinese Disease Prevention and Control Information System. Population distribution and transmission routes were analyzed, and changing trends in case number were analyzed using average annual percent change (AAPC) and annual percent change (APC).
Results:
A total of 4 409 HIV/AIDS cases aged 15 years and older were newly reported in Shangcheng District from 2006 to 2022, including 3 932 males (89.18%). There were 3 447 cases (78.18%) under 50 years old and 962 cases (21.82%) being 50 years and older. Sexual contact was a predominant transmission route, with 4 326 cases accounting for 98.12%, including 2 626 cases (59.56%) with homosexual contact and 1 700 cases (38.56%) with heterosexual contact. The number of HIV/AIDS cases showed an overall upward trend from 2006 to 2022 (AAPC=13.038%, P<0.05), with an upward trend from 2006 to 2015 (APC=42.578%, P<0.05) and a downward trend from 2015 to 2022 (APC=-19.713%, P<0.05). The increase in the number of cases aged 50 years and older group was faster than that of cases aged under 50 years (AAPC=22.641% vs. 11.162%, both P<0.05). The increase in the number of cases with homosexual contact transmission was faster than that of cases with heterosexual contact transmission (AAPC=20.417% vs. 7.455%, both P<0.05).
Conclusions
The number of newly reported HIV/AIDS cases aged 15 years and older in Shangcheng District performed an overall upward trend from 2006 to 2022. The cases aged 50 years and older and transmitted through homosexual contact increased rapidly, which should be taken seriously.

Objective:
To analyze the characteristics of young students inquiry to voluntary counseling and testing (VCT) clinics, and to provide reference for AIDS prevention and control effectiveness of local schools.
Methods:
A total of 1 223 students aged 7-28 years were collected and characterized through HIV Testing Consulting Information Management System in Shangcheng VCT clinics during 2016-2020. The epidemic characteristics were analyzed by cross sectional studies.
Results:
Young students accounted for 25.21%(1 223/4 852) of the total counseling population in VCT clinics from 2016 to 2020. The main reason for counseling was non high risk (28.29%, 346 cases), followed by MSM (26.41%, 323 cases) and non commercial non fixed heterosexual behavior(25.92%, 317 cases). The counseling proportion of non commercial non fixed heterosexual behavior and commercial heterosexual sex behavior declined with time( χ 2 trend =-6.04, -3.59, P <0.01). The average of HIV positive detection rate among young students was 3.03%(37 cases), which increased with time( χ 2 trend=2.45, P <0.01).
Conclusion
Sex education and HIV/AIDS knowledge education are necessary in primary and secondary schools. Targeted strategies are in great need in terms of MSM behavior intervention.
