Objective To analyze the epidemic characteristics of AIDS in Hainan Province, so as to provide the evidence and guild direction for prevention and control strategy of AIDS. Methods Through the AIDS prevention and control basic information system, the historical card data and statistical report data of case reports by the end of 2018 were collected and analyzed. Results A total of 2 937 cases of surviving HIV infections and AIDS patients had been reported in Hainan Province by the end of 2018. There were two cities with more than 500 reported cases, accounting for 59.18% of the total number of cases in the province. The rate of male to female was 5.85 : 1. The minimum age was 3 months and the maximum age was 91 years old, the age group between 20 and 40 accounted for 62.65%. The proportions of the current survival and the newly reported cases of sexual transmission in 2018 were 89.62% and 96.95%, respectively. The proportion of men who have sex with men (MSM) transmission of surviving cases in Haikou and Sanya was about 60%. The proportion of MSM transmission in the age groups 15-<20 and 20-<30 accounted for 80.00% and 71.62%, respectively. The proportion of heterosexual transmission in the age group of 60 years and above accounted for 89.73%; The proportion of MSM transmission of unmarried cases accounted for 64.74%, the proportion of heterosexual transmission of married cases accounted for 72.24% ; The proportion of MSM transmission in colleges and above accounted for 72.72%, The proportion of heterosexual transmission in junior high school and below accounted for 60.48%. There were significant differences in the proportions of sexual transmission among different age groups, marital status and educational level (P<0.05). Conclusion Regional distribution of AIDS epidemic is obvious in Hainan, mainly by sexual transmission. Different regions and populations with different characteristics have different modes of sexual transmission. According to local conditions, AIDS prevention and control strategies and measures should be formulated for different groups. [ABSTRACT FROM AUTHOR]

Objective: To understand the routes of newly reported HIV/AIDS cases with heterosexual mode of transmission in six districts of Chongqing city, and to provide evidence for HIV/AIDS prevention and control programs regarding heterosexual mode of transmission on HIV. Methods: HIV/AIDS cases that were newly reported as with heterosexual mode of transmission in six districts of Chongqing from July 1st to October 1st in 2019, were recruited in the study. Information related to their sociodemographic characteristics and heterosexual behaviors was collected. A self-designed questionnaire was used in this face-to-face survey. Results: A total of 312 HIV/AIDS cases with heterosexual mode of transmission were recruited. Most of them were males (207, 66.3 % ), aged 50 years or over (210, 67.3 % ), having junior high school or lower education (252, 80.8 % ), married or cohabitating (200, 64.1 % ). 48.7 % (152/312) of them were infected through commercial sexual contact while 40.4 % (126/312) of them were infected by spouses or stabled partners. 10.9 % (34/312) of them were infected by non-marital and non-commercial sexual contacts. Significant differences were noticed on the infection mode of heterosexual transmission in gender, age and occupation ( P <0.05). Results from the multivariate logistic regression analysis revealed that: male ( OR =822.34, 95 %CI : 103.99-6 503.10), junior high school and lower education level ( OR =3.02, 95 %CI : 1.05-8.66), household chores and underemployed ( OR =0.23, 95 %CI : 0.07-0.76) were influencing factors on HIV infection that were through commercial sexual contacts. Male ( OR =29.20, 95 %CI : 9.40-90.75), junior high school and lower education level ( OR =4.28, 95 %CI : 1.24-14.81) were influencing factors on HIV infection, through non-marital and non-commercial sexual contacts. In addition to meeting sexual partners in offline places, some HIV/AIDS patients with heterosexual mode of transmission had developed sexual partnerships through online dating and with low-grade venue as the main place for sex engagement. Conclusions: Newly reported HIV/AIDS cases under heterosexual mode of transmission in Chongqing were mainly infected from offline low-grade venues, and caused by commercial sexual engagement. The routes of HIV infections that caused by heterosexual contact should be deeply understood in order to develop targeted intervention programs.

Objective: To understand the characteristics and associated factors of newly reported HIV/AIDS cases with non-marital or non-commercial heterosexual transmission, in Guangxi Zhuang Autonomous Region (Guangxi), 2015-2018. Methods: Information of newly reported HIV/AIDS cases aged ≥18 years in Guangxi between 2015 and 2018 was collected from the National Comprehensive HIV/AIDS Information System. Unconditional logistic regression model was used to access those factors that were associated with HIV infections through non-marital or non-commercial heterosexual contact. Results: Between 2015 and 2018, a total number of 35 497 HIV/AIDS cases, aged ≥18 years were newly reported in Guangxi. Among them, 32 648 (92.0 % ) were infected heterosexually while 10 500 were infected through non-marital or non-commercial heterosexual behavior. Non-marital or non-commercial heterosexual transmission accounted for 29.6 % (10 500/35 497) of the newly reported HIV/AIDS cases, and 32.2 % (10 500/32 648) of those with heterosexual transmission. Males counted for 53.5 % (5 617/10 500) of non-marital or non-commercial heterosexual transmission and males to females ratio was 1.2∶1 (5 617∶4 883). Those married or had regular sexual partners counted for 55.9 % (5 873/10 500). Commercial heterosexual transmission appeared the main mode of HIV transmission for males (64.4 % ,16 516/25 633) while main mode for females was non-marital or non-commercial heterosexual transmission and counted for 49.5 % (4 883/9 864). Results from the multivariate logistic regression analysis showed that adjusted OR of female HIV/AIDS infected HIV via non-marital or non-commercial heterosexual transmission, was 3.98 times (95 %CI : 3.78-4.20) hight than that of males. Among the group aged<50 years and the aged 50-59 years, the adjusted OR s were 1.35 times (95 %CI : 1.27-1.44) and 1.13 times (95 %CI : 1.05-1.21) hight than that of aged ≥60 years. Those who were single/divorced/widowed, the adjusted OR was 1.53 times (95 %CI : 1.45-1.61) hight than that of those married/regular partners. Those with junior high school education, high school education and above the adjusted OR s were 1.22 times (95 %CI : 1.16-1.29) and 1.18 times (95 %CI : 1.10-1.27), compared to those only with education levels of primary school or below. Conclusions: The number of HIV/AIDS cases via non-marital or non-commercial heterosexual transmission accounted for nearly 30.0 % of all the routes of HIV transmission in Guangxi, 2015-2018. Female, aged<60 years old, single/divorced/widowed and having had junior and above high school education etc ., appeared as risk factors on non-marital or non-commercial heterosexual transmission, among newly reported HIV/AIDS in Guangxi.

Objective: To describe the characteristics of newly reported HIV/AIDS cases via non-marital or non-commercial heterosexual transmission and to find out the relative factors in Hangzhou, from 2015 to 2017. Methods: Data were collected through the national HIV/AIDS comprehensive control and prevention data system. Study subjects would include those reported HIV/AIDS cases who were residents of Hangzhou and were infected via non-marital heterosexual transmission, between January 1, 2015 and December 31, 2017. Demographic characteristics and behavioral information were collected. χ (2) test was used to compare different characteristics of the non-married heterosexual transmission subjects. Logistic regression was used to assess factors that associated with non-marital but non-commercial HIV heterosexual transmission with SPSS. 20 software used to analyze statistically. Results: Non-marital HIV heterosexual transmission accounted for 38.03% (1 393/3 663) of the total new reported HIV/AIDS cases in 2015-2017. Out of the 1 393 HIV/AIDS cases, those infected through non-marital but non-commercial heterosexual transmission accounted for 50.83% (708/1 393), and those through non-martial commercial transmission was accounted for 49.17% (685/1 393). Male to female ratio was 3.51 ∶ 1 (1 084/309). Male HIV cases reported that their major way of infection was via non-marital commercial transmission (670/1 084, 61.81%), while female patients reported the way was via non-marital non-commercial (294/309, 95.1%). Results from multivariate logistic analysis showed that the related risk factors and OR s for non-marital but non-commercial transmission appeared as: female (a OR =48.25, 95 %CI : 26.94- 88.44),<30 year olds (a OR =2.43, 95 %CI : 1.31-4.51), 30-39 year olds (a OR =1.92, 95 %CI : 1.11- 3.33), 40-49 year olds (a OR =1.80, 95 %CI : 1.08-3.00), married or unmarried ( vs. divorced or widowed, a OR =1.57, 95 %CI : 1.10-2.24; a OR =1.78, 95 %CI : 1.15-2.78), high school and above of education level ( vs. primary school and under of education level, a OR =1.82, 95 %CI : 1.18-2.80), administrative officers or employee ( vs. farmers, a OR =2.03, 95 %CI : 1.04-1.91). Number of non- marital partners less than 5 ( vs. number of non-marital partners more than 5, a OR =10.65, 95 %CI : 6.41-17.42). Conclusions: HIV/AIDS cases with non-marital heterosexual transmission accounted for considerable proportion regarding the HIV transmission in Hangzhou from 2015 to 2017. Differences were found in the following factors as non-marital and non-commercial heterosexual transmission with diverse gender, age, marital status, educational level and occupation among of the HIV/AIDS patients.
