BACKGROUND The outbreak of monkeypox around the world in May 2022 is another health threat for who have sex with men (MSM), which accounts for almost all patients. OBJECTIVE This study aimed to describe the knowledge of Monkeypox, worries about monkeypox, their awareness of prevention strategies, willingness towards monkeypox vaccination and their correlates factors among MSM in China. METHODS Methods: In this regard, we conducted a cross-sectional survey of MSM in southern China from August to September 2022. Multivariate logistic regression was used to explore the correlates willingness of monkeypox vaccination and its correlates. RESULTS Results: Participants (N=1093) ranged in age from 18 to 70 years and mean age was 27.9 years. Over two-thirds 343(68.6%) had anal sex for one to five times in the past three months .999(91.4%) of participants were willing to receive a monkeypox vaccine and 639(89.4%) obtained information about monkeypox through the Internet. In multivariable analysis, considered the vaccine to be safe (aOR=6, 95%CI: 1.402–25.678), agreed that it was necessary for the government to promote smallpox/monkeypox vaccination in China (aOR=6.195, 95%CI: 1.038–36.993), agreed that smallpox/monkeypox vaccine should be given priority to MSM (aOR=8.88, 95% CI:1.742–45.274) and whose friends or sexual partners had received the monkeypox vaccination (aOR=14.305, 95%CI: 2.621–78.070) were more likely to be willing to receive monkeypox vaccine. Participants (729,66.7%) were aware that they were at a high risk of monkeypox infection and agree that vaccine should be given as a priority to MSM (661,60.5%). Those who were married (aOR=0.155, 95% CI: 0.039–0.614), had engaged in anal sex 4–6 times per week in the past three months (aOR=0.279, 95% CI: 0.089–0.875) and who received Jynneos (aOR=0.111, 95% CI: 0.013–0.922) were less likely to take the monkeypox vaccination. CONCLUSIONS Conclusions: There was a relatively high willingness of monkeypox vaccination among MSM in China. The hesitancy of monkeypox vaccination can be effectively addressed by eliminating concerns about the safety of the vaccine and adverse reactions to vaccination, and by increasing the acceptance of monkeypox vaccination of their peers among MSM. CLINICALTRIAL Ethical considerations The study was approved by the Human Research Ethics Committee of Guangxi Medical University under protocol 20220132. Written informed consent was obtained from all participants prior to enrolment in the study.
Background To analyze the trends of HIV-1 and syphilis prevalence as well as associated factors among local Chinese female sex workers (LCFSWs) and cross-border migrant female sex workers (CMFSWs) in Sino-Vietnam border cities in Guangxi, China. Methods A consecutive cross-sectional study was conducted from 2010 to 2018 in three border cities in Guangxi. The survey was conducted through face-to-face interview with a structured questionnaire. HIV-1 and syphilis infections were tested simultaneously. Cochran-Armitage analysis was used to assess the trends of HIV-1, syphilis and HCV prevalence, as well as the trend of risk behaviors, HIV/AIDS knowledge and prevention services. Multivariate logistics regression analysis was used to identify factors associated with HIV-1 and syphilis infection.Results Totally, 19873 LCFSWs and 1723 CMFSWs were enrolled. The overall prevalence of HIV-1 and syphilis infection was 0.91% and 5.14%, respectively. The HIV-1 prevalence among CMFSWs was higher than that among LCFSWs, without a declined trend. However, a downward trend was observed among LCFSWs. Overall, the main associated factors of HIV-1 infection among CMFSWs shifted from age >35 years old, staying in current residence for >12 months, self-reporting sexually transmitted infections (STIs) in the last year during 2010-2015 to inconsistent condoms use in commercial sex in last month, not receiving peer education and self-reporting STIs in the last year during 2016-2018. The main correlated factors of syphilis infection among CMFSWs changed from history of illicit drug use, staying in current residence for more than 12 months, self-reporting of STIs and inconsistent condoms use in commercial sex in the past month during 2010-2015 to working in low-tier venues, self-reporting of STIs in the last year, and sexing with commercial male clients who used aphrodisiac drugs during 2016-2018. For LCFSWs, the relative strong associated factors of HIV-1 infection shifted from receiving less than 6 years of education, illicit drugs use, and self-reporting STIs in the last year during 2010-2015 to sexing with commercial male clients who use aphrodisiac drugs and self-reporting of STIs during 2016-2018, while the main factors of syphilis infection changed from self-reporting STIs in the last year, history of illicit drug use and receiving less than 9 years of education during 2010-2015 to self-reporting of STIs in the last year, sexing with commercial male clients who use aphrodisiac drugs, and history of illicit drugs use during 2016-2018.Conclusions The relatively higher prevalence of HIV-1 infection and frequent risk behaviours among CMFSWs in border cities in Guangxi, indicating that CMFSWs is the high-risk population for HIV-1 infection and transmission in the region, and is the key population of HIV/AIDS prevention and control. Meanwhile, the change of HIV infection-associated risk factors over time suggests that HIV intervention strategies need to be changed accordingly.
