ABSTRACT
BACKGROUND AND OBJECTIVES: In 2016, France allowed men who have sex with men (MSM) to donate blood if they had not had sex with men in the previous 12 months. In April 2020, this restriction was relaxed to 4 months due to the lack of negative impact observed on blood safety. This study assesses the impact of reducing this deferral period on epidemiological surveillance indicators. MATERIALS AND METHODS: This study compares infection surveillance indicators between two 30-month periods before (P1) and after (P2) this second deferral change. RESULTS: Overall, 79 donations tested positive for human immunodeficiency virus (HIV) (49 in P1 and 30 in P2), 322 for hepatitis C virus (HCV) (185 and 137), 622 for hepatitis B virus (HBV) (355 and 267) and 1684 for syphilis (799 and 885). Positive donation rates decreased between P1 and P2, except for syphilis: HIV (0.07/10,000 donations vs. 0.04; p > 0.5), HCV (0.25 vs. 0.20; p < 0.05), HBV (0.49 vs. 0.39; p < 0.01) and syphilis (1.10 vs. 1.29; p < 0.001). For all three viruses, residual risks of transmission by transfusion did not increase: HIV (1/7,800,000 donations vs. 1/10,500,000), HCV (1/25,200,000 vs. 1/47,300,000) and HBV (1/6,400,000 vs. 1/6,000,000). CONCLUSION: Reducing the deferral period for MSM in April 2020 did not negatively impact residual risks, which remained very low, or the rate of positive donations, except for syphilis, which requires careful monitoring. To ensure equal access to blood donation, MSM have been allowed to donate blood under the same conditions as other donors since March 2022 (i.e., no more than one sexual partner in the last 4 months).
ABSTRACT
We examined changes in HIV testing and medical care among men who have sex with men (MSM) in Russia. Data come from the 2010 and 2017 waves of the European MSM Internet Survey. From 2010 to 2017 there was an increase in the proportion who had ever received an HIV test (+ 11.2%), had tested for HIV in the last year (+ 2.1%), had ever taken antiretroviral therapy (ART) (+ 31.9), were currently taking ART (+ 31.5%), and had an undetectable viral load (+ 19.4%). These results are encouraging, yet they also reveal that substantial proportions of MSM experience considerable unmet prevention and treatment needs.
RESUMEN: Examinamos los cambios en las pruebas de detección de VIH y la atención médica entre hombres que tienen sexo con hombres (HSH) en Rusia. Los datos provienen de las olas de 2010 y 2017 de la Encuesta Europea de Internet para HSH. De 2010 a 2017 hubo un aumento en la proporción de quienes alguna vez se habían hecho una prueba de VIH (+ 11.2%), se habían hecho una prueba de VIH en el último año (+ 2.1%), alguna vez habían tomado terapia antirretroviral (TAR) (+ 31.9%), estaban tomando TAR actualmente (+ 31.5%) y tenían una carga viral indetectable (+ 19.4%). Estos resultados son alentadores, pero también revelan que una proporción sustancial de HSH experimenta considerables necesidades de prevención y tratamiento no satisfechas.
ABSTRACT
Background: Men who have sex with men (MSM) are at a high risk for HIV infection. While pre-exposure prophylaxis (PrEP) is an effective oral preventive strategy, its success is largely dependent on consistent medication adherence. Objective: The aim of this study was to develop the machine learning web application and evaluate the performance in predicting PrEP adherence. Methods: The PrEP prospective cohort study of the MSM population conducted in Western China from 2019 to 2023, and we collected adherence data and personal characteristics data from 747 MSM. Predictor variables were screened and the performance of several machine learning methods in predicting nonadherent behaviors were compared. Results: A total of 11 candidate variables were screened that predicted nonadherent behaviors. We developed and evaluated five machine learning models that performed well in predicting adherence. Attitudes of male sexual partners, self-efficacy, HIV testing, number of male sexual partners, and risk perception were the most important predictors of adherence. The optimal prediction model was displayed in a shiny web application for online calculation of the probability of occurrence of nonadherent behaviors among MSM. Conclusions: Machine learning performed well in predicting nonadherent behaviors among MSM. An interactive and intuitive web application can help identify individuals who may have nonadherent behaviors, resulting in improved medication adherence and increased prevention efficacy.
ABSTRACT
HLA-I/KIR genotypes influence HIV-1 disease progression and viral load, but their role in primary infection is uncertain. Inconsistent results from previous studies suggest that the inoculum size and transmission route-parenteral vs. sexual-may influence this association. We conducted a GWAS in a population of people living with HIV-1 and HIV-1-exposed seronegative individuals exposed to the virus through the sexual route. Our data do not support any role of the HLA/KIR system in susceptibility to sexually transmitted HIV-1 infection. The genetics basis of HIV-1 viral load and disease progression are distinct from the genetics of HIV resistance, a paradox worth exploring.
ABSTRACT
BACKGROUND: Combining pathogen reduction technology (PRT) with blood screening may alleviate concerns over the risk of transfusion-transmitted infections (TTI) and support changes in blood donor selection to potentially increase blood availability. This study aimed to estimate the residual risk of human immunodeficiency virus (HIV), hepatitis B virus (HBV), and hepatitis C virus (HCV) transfusion-transmission in Canada after implementing PRT, while eliminating deferrals for sexual risk behaviors. STUDY DESIGN AND METHODS: A probabilistic approach that combined Bayesian networks with Monte Carlo simulations was used to estimate the risk of transfusing HIV-, HBV-, or HCV-contaminated blood components. Different scenarios were considered to compare the current residual risk after PRT implementation, with and without donor deferral criteria for sexual risk behaviors. Donor profiles and blood component outcomes were simulated based on a literature review including the prevalence and incidence of HIV, HBV, and HCV in the Canadian blood donor population; the use of current blood screening assays; and HIV, HBV, and HCV blood donor viral loads. RESULTS: In the universal PRT scenario (i.e., with PRT/without deferral criteria), the estimated risks of HIV, HBV, and HCV transmission were significantly lower than those in the currently observed scenario (i.e., without PRT/with deferral criteria). CONCLUSIONS: This risk model suggests that PRT for platelets and plasma (and eventually for RBCs when available) significantly reduces the residual risks of HIV, HBV and HCV transfusion-transmission and could enable the removal of blood donor deferral criteria for sexual risk behaviors.
ABSTRACT
BACKGROUND: Cobalt, an essential trace element, is vital for maintaining human nervous system function, aiding in DNA synthesis, and contributing to red blood cell production. It is helpful for disease diagnosis and treatment plan evaluation by precisely monitoring its concentration changes in the human body. Despite extensive efforts made, due to its ultra-low concentration, the current limit of detection (LOD) as reported is still inadequate and cannot be satisfied with the precise clinical applications. Therefore, it is crucial to develop novel label-free sensors with high sensitivity and excellent selectivity for detecting trace amounts of Co2+. RESULTS: Here, an ultrasensitive optical fiber SPR sensor was designed and fabricated for label-free detection of Co2+ with ultra-low concentration. It is achieved by modifying the carboxyl-functionalized CQDs on the AuNPs/Au film-coated hetero-core fiber, which can specifically capture the Co2+, leading to changes in the fiber's surface refractive index (RI) and subsequent SPR wavelength shifts in the transmission spectrum. Both the Au film and AuNPs on the fiber are modified with CQDs, leveraging their large surface area to enhance the number of active sites and probes. The sensor exhibits an ultra-high sensitivity of approximately 6.67 × 1019 nm/M, and the LOD is obtained as low as 5.36 × 10-20 M which is several orders of magnitude lower compared to other conventional methods. It is also experimentally demonstrated that the sensor possesses excellent specificity, stability, and repeatability, which may be adapted for detecting real clinical samples. SIGNIFICANCE: The CQDs-functionalized optical fiber SPR sensor exhibits substantial potential for precisely detecting Co2+ of trace amounts, which is especially vital for scarce clinical samples. Additionally, the sensing platform with sample sensor fabrication and measurement configuration introduces a novel, highly sensitive approach to biochemical analysis, particularly adapting for applications involving the detection of trace targets, which could also be employed to detect various biochemical targets by facile modification of CQDs with specific groups or biomolecules.

Persistent pre-exposure prophylaxis (PrEP) use reduces the risk of HIV infection, yet uptake lags among those with the greatest need. Sexual identity stigma may be a significant barrier to PrEP awareness and use among high-risk communities. The primary aim of this study was to determine whether sexual identity was related to PrEP awareness and use. This multi-site HIV Prevention Trials Network (HPTN) study (HPTN 078) focuses on men who have sex with men (MSM) (n=335) who were HIV-negative at screening. The majority of participants were non-white (62.1%), younger than 35 (57.9%), single (79.1%), and aware of PrEP, yet had never taken PrEP (52.5%). Participants completed questionnaires including sexual history and identity; lesbian, gay, bisexual, transgender, queer (LGBTQ) community engagement; PrEP awareness and use; and several measures of sexual identity stigma including family and friend stigma, general societal stigma, and anticipated healthcare stigma. Univariate and multinomial logistic regression models helped to determine factors associated with PrEP awareness and use. There were stark disparities in PrEP awareness comparing Black and White participants; 50% of Black participants reported being PrEP unaware vs 11.8% of White participants. In this sample, gay sexual identity (compared to bisexual identity) was associated with increased PrEP awareness (AOR 6.66) and use (AOR 16.9). Additionally, 29% of the association between sexual orientation and PrEP use was mediated through internalized stigma. Given low PrEP uptake among MSM, interventions that address sexual identity stigma may motivate greater PrEP uptake.
ABSTRACT
BACKGROUND: In Vietnam and other global settings, men who have sex with men (MSM) have become the population at greatest risk of HIV infection. Although HIV pre-exposure prophylaxis (PrEP) has been implemented as a prevention strategy, PrEP outcomes may be affected by low persistence and adherence among MSM with unhealthy alcohol use. MSM have a high prevalence of unhealthy alcohol use in Vietnam, which may affect PrEP outcomes. METHODS: Design: We will conduct a two-arm hybrid type 1 effectiveness-implementation randomized controlled trial of a brief alcohol intervention (BAI) compared to the standard of care (SOC) at the Sexual Health Promotion (SHP) clinic Hanoi, Vietnam. PARTICIPANTS: Sexually active MSM (n=564) who are newly initiating PrEP or re-initiating PrEP and have unhealthy alcohol use will be recruited and randomized 1:1 to the SOC or BAI arm. A subgroup of participants (n=20) in each arm will be selected for longitudinal qualitative interviews; an additional subset (n=48) in the BAI arm will complete brief quantitative and qualitative interviews after completion of the BAI to assess the acceptability of the intervention. Additional implementation outcomes will be assessed through interviews with clinic staff and stakeholders (n=35). INTERVENTION: Study participants in both arms will receive standard care for PrEP clients. In the BAI arm, each participant will receive two face-to-face intervention sessions and two brief booster phone sessions, based on cognitive behavioral therapy and delivered in motivational interviewing informed style, to address their unhealthy alcohol use. OUTCOMES: Effectiveness (PrEP and alcohol use) and cost-effectiveness outcomes will be compared between the two arms. Intervention implementation outcomes (acceptability, feasibility, adoption) will be assessed among MSM participants, clinic staff, and stakeholders. DISCUSSION: This proposed trial will assess an alcohol intervention for MSM with unhealthy alcohol use who initiate or re-initiate PrEP, while simultaneously preparing for subsequent implementation. The study will measure the effectiveness of the BAI for increasing PrEP persistence through reducing unhealthy alcohol use in a setting where excessive alcohol consumption is a normative behavior. If effective, implementation-focused results will inform future scale-up of the BAI in similar settings. TRIAL REGISTRATION: NCT06094634 on clinicaltrials.gov. Registered 16 October 2023.

This study assessed pre-exposure prophylaxis (PrEP) awareness, knowledge, and attitudes in a sample of 1389 men who have sex with men (MSM). Using a self-report survey, we measured PrEP knowledge mean scores, attitudes toward PrEP, and awareness rates to identify the key influences on PrEP uptake. PrEP awareness among participants was 66.3%, with 33.7% having never heard of PrEP. Approximately 4.5% had previous experience with PrEP but were not current users, while only 2.7% reported that they were currently taking it. Logistic regression analysis revealed that the significant predictors of PrEP awareness were educational attainment, marital status, prior HIV testing knowledge, and attitudes toward PrEP. Several demographic factors were not significant predictors of intention to use PrEP; however, using the internet to meet partners, number of partners, HIV testing, positive attitudes, and reduced perceived barriers played a critical role in shaping PrEP use intentions. These findings highlight the critical role of targeted educational strategies and tailored public health messaging in enhancing the awareness and intention to use PrEP among MSM.
ABSTRACT
Background: Little is known about how best to reach people with social marketing messages promoting use of clinical HIV and sexually transmitted infection (STI) services. Objective: We evaluated a multiplatform, digital social marketing campaign intended to increase use of HIV/STI testing, treatment, and prevention services among gay, bisexual, and other men who have sex with men (MSM) at an LGBTQ+ (lesbian, gay, bisexual, transgender, queer, and/or questioning) community health center. Methods: We evaluated engagement with a social marketing campaign launched by Open Door Health, the only LGBTQ+ community health center in Rhode Island, during the first 8 months of implementation (April to November 2021). Three types of advertisements encouraging use of HIV/STI services were developed and implemented on Google Search, Google Display, Grindr, and Facebook. Platforms tracked the number of times that an advertisement was displayed to a user (impressions), that a user clicked through to a landing page that facilitated scheduling (clicks), and that a user requested a call to schedule an appointment from the landing page (conversions). We calculated the click-through rate (clicks per impression), conversion rate (conversions per click), and the dollar amount spent per 1000 impressions and per click and conversion. Results: Overall, Google Search yielded the highest click-through rate (7.1%) and conversion rate (7.0%) compared to Google Display, Grindr, and Facebook (click-through rates=0.4%-3.3%; conversion rates=0%-0.03%). Although the spend per 1000 impressions and per click was higher for Google Search compared to other platforms, the spend per conversion-which measures the number of people intending to attend the clinic for services-was substantially lower for Google Search (US $48.19 vs US $3120.42-US $3436.03). Conclusions: Campaigns using the Google Search platform may yield the greatest return on investment for engaging MSM in HIV/STI services at community health clinics. Future studies are needed to measure clinical outcomes among those who present to the clinic for services after viewing campaign advertisements and to compare the return on investment with use of social marketing campaigns relative to other approaches.

OBJECTIVES: The saliva of individuals with oropharyngeal gonorrhoea can contain viable Neisseria gonorrhoeae. This study examined if using saliva as a lubricant for masturbation is a risk factor for urethral gonorrhoea among men who have sex with men (MSM). METHODS: In this cross-sectional study, MSM aged ≥18 years attending the Melbourne Sexual Health Centre between February 2021 and December 2023 were surveyed. Data were collected on sexual activities in the past seven days, including receiving fellatio, condomless insertive anal sex, docking, and using saliva for masturbation. Multivariable logistic regression examined associations between these exposures and urethral gonorrhoea. RESULTS: The median age of the 3114 men was 32 (IQR: 27-40), with 4.7% (n=145) testing positive for urethral gonorrhoea. Urethral gonorrhoea was independently associated with an increasing number of partners for condomless insertive anal sex (p<0.001). It was not significantly associated with receiving fellatio (p=0.613), docking (p=0.207), or using saliva for masturbation (p=0.117). However, of the 110 men who only used saliva for masturbation, two (1.8%) had urethral gonorrhoea, and one (0.9%) had both urethral and oropharyngeal gonorrhoea. CONCLUSION: Condomless insertive anal sex is the leading risk factor for urethral gonorrhoea and not using saliva as a lubricant for masturbation.
ABSTRACT
BACKGROUND: In the Hebei province, Human Immunodeficiency Virus type one (HIV-1) recombinant strains of subtypes B, C, and CRF01_AE are emerging very rapidly and diversely. OBJECTIVE: In order to confirm the characteristics of novel recombination forms, we aimed to analyze HIV-1 Near-full-length Genome sequences (NFLGs) obtained from three Men who have Sex with Men (MSM) in this study. METHOD: Phylogenetic trees were constructed and breakpoints analysis was performed based on the NFLGs and each gene fragment to examine the gene recombination patterns of three new HIV-1 NFLGs. RESULT: HIV-1 subtypes CRF01_AE and B were combined to generate the recombinant structures of the NFLGs 610 and 687. CRF01_AE, B, and C were combined to generate the recombinant structures of the NFLG 825. According to the NFLG phylogenetic tree, the NFLG 825 clustered with CRF65_cpx and the NFLGs 610 and 687 clustered with CRF68_01B. The recombination breakpoints analysis revealed that the recombination pattern of the NFLGs 610 and 687 was the insertion of subtype B fragment into the CRF01_AE backbone. Subregions I, II, and III were derived from CRF01_AE, subtype B, and CRF01_AE, respectively. The recombination pattern of the NFLG 825 contained ten fragments of subtypes CRF01_AE, C, and B. Finally, the above factors were formed using phylogenetic trees and breakpoints analysis, which were combined to get two CRF68_01B forms and one CRF65_cpx form. CONCLUSION: Our findings have suggested that it is crucial to keep an eye on the genetic diversity of HIV-1 in Hebei province.
ABSTRACT
Introduction: Homosexual transmission has contributed greatly to the current HIV-1 epidemic in Hebei province, China. Dolutegravir (DTG) will be conditionally used as a component of free antiretroviral therapy (ART) according to manual for national free anti-AIDS treatment drugs (2023 edition) issued by China in June 2023. However, current genetic characteristics and pretreatment drug resistance (PDR) to proteinase inhibitors (PIs), reverse transcriptase inhibitors (RTs) and integrase strand transfer inhibitors (INSTIs) of HIV-1 in this population have remained unclear. Methods: Serial consecutive cross-sectional analyses for HIV- 1 infection trend, genetic characteristics, PDR and molecular transmission networks were conducted from 2018 to 2022. All of participants were HIV-1- infected MSM newly diagnosed at the HIV surveillance points (HSPs) in Hebei, China. Evidence of PDR was confirmed using the world health organization (WHO) list for surveillance of drug resistance mutations. Results: In this study, a total of 14 HIV-1 subtypes were circulating in the HSPs of Hebei province, China. CRF01_ AE (51.9%, 350/675), CRF07_BC (30.4%, 205/675), B (6.2%, 42/675) and URFs (5.8%, 39/675) were the four most predominant subtypes among MSM. And, CRF07_BC (r > 0) and URFs (r > 0) indicated an increasing trend, respectively; however, CRF01_AE (r < 0) showed a decline trend. The overall prevalence of HIV-1 PDR showed a substantial increase from 6.3% in 2018 to 7.9% in 2022. The prevalence of NNRTI-PDR was the highest (5.8%, 39/675), followed by INSTIs (2.4%, 16/675), NRTIs (0.6%, 4/675) and PIs (0.3%, 2/675). Furthermore, extensive HIV-1 strains bearing PDR were circulating in the MSM population via molecular transmission networks for major HIV-1 subtypes, especially CRF01_AE and CRF07_BC. Discussion: Our findings reflect that HIV-1 epidemic in the MSM population is complex and severe in Hebei, China. Therefore, it is urgent for us to implement more effective intervention measures to limit the further dissemination of HIV-1, especially the spread of HIV-1 INSTI-PDR strains.
ABSTRACT
Risk factors for cytomegalovirus (CMV) acquisition in men having sex with men remain unclear. Seroprevalence, incidence, risk factors and shedding of CMV were analyzed among participants enrolled in the HIV pre-exposure prophylaxis IPERGAY-ANRS trial. Among the 417 participants tested, 382 were seropositive at baseline (prevalence of 91.6%; 95%CI[88.5-94.1]) and 10/35 seroconverted during the study (incidence of 17.1 per 100 person-years; 95%CI[8.2-31.3]). A high number of sexual partners was independently associated with CMV seroprevalence. Shedding among CMV-seroconverters was reported for 6/9 and 2/9 at the oral and anal levels, respectively. Our data supports transmission of CMV during sexual contacts. Study part of the ANRS-IPERGAY Clinical trial: ClinicalTrials.gov number, NCT01473472.
ABSTRACT
This study aimed to evaluate the interest in event-driven PrEP (ED-PrEP) among men who have sex with men (MSM) using daily PrEP in Mexico's PrEP demonstration project between 2019 and 2020. We compared participants interested or not in ED-PrEP during their first-month visit and identified associated factors. Of 1,021 MSM attending their first-month visit, 7% had previous knowledge of ED-PrEP, but 40% were interested in ED-PrEP. However, over 50% perceived the scheme as less protective than daily PrEP. Having doubts about ED-PrEP's level of protection was related to less interest in the scheme (aOR = 0.11; CI = 0.07-0.18), just like reporting perceived barriers such as having frequent sex (aOR = 0.06; CI = 0.03-0.14), unplanned sex (aOR = 0.17; CI = 0.11-0.27), forgetting the medicine (aOR = 0.06; CI = 0.03-0.12), or difficulty carrying the medicine (aOR = 0.13; CI = 0.07-0.25). Finally, reporting not taking PrEP for >20 days in the last month (aOR = 0.05; CI = 0.01-0.27) diminished interest in ED-PrEP. In conclusion, few MSM daily PrEP users knew about ED-PrEP yet many were interested in it, suggesting the importance of awareness campaigns regarding ED-PrEP's effectiveness. The lack of interest in ED-PrEP among participants with poor adherence to daily PrEP indicates that they might prefer long-acting PrEP or HIV prevention strategies without medication.
ABSTRACT
For Hispanic/Latino MSM (HLMSM) in the South, HIV burden remains high, and HIV elimination is a national priority. Between July and September 2016, using a strengths-based approach informed by resilience theory, we conducted qualitative interviews with HIV-negative HLMSM in five southern cities in the United States with elevated HIV prevalence. We analyzed data using a qualitative content analysis approach, assessing for interrater reliability. A brief behavioral survey was also conducted. We enrolled 51 HLMSM (mean age = 33 years, range = 15-63). HLMSM discussed the climate of fear about HIV and homosexuality impeding HIV prevention, including the impact of stigma and taboo. Three main strengths-based strategies emerged for preventing HIV: assessing partner risk, establishing boundaries for sexual interactions, and self-education. Future HIV prevention efforts may benefit from balancing risk-based approaches with those that emphasize resilience, address partner trustworthiness and safety, and focus on providing novel outlets for HIV prevention education.
ABSTRACT
PURPOSE: Asymptomatic pharyngeal gonorrhoea could play an important role in transmission and should be screened for in persons at risk. We investigated the sensitivity of oral gargle samples to detect N. gonorrhoea and describe the frequency of infection by anatomical site. METHODS: From June 2021 to July 2022 persons diagnosed with gonorrhoea in the STI/HIV department were asked to provide self-collected specimens for single-site testing by NAAT from throat (by gargling and swabbing), anorectum, and first-void urine. RESULTS: 104 episodes of gonorrhoea were analysed in 88 individuals. The median age was 33 years, 85 persons (96.5%) were male. The pharynx was the most common site of infection (71 cases, 68.2%); in 26 persons (25.0%) it was the only site of infection. Anorectal infection was detected in 65 cases (62.5%) and urogenital infection in 25 cases (24.0%). In 46 cases (44.2%) infection was detected in more than one anatomical site. Gargling was less sensitive than throat swabbing to detect pharyngeal infection (85.9% versus 97.2%, p = .038), but was preferred by patients. Only 4 of 71 pharyngeal infections (5.6%) were symptomatic; anorectal and urogenital infections were symptomatic in 12.3% and 76.0% of cases, respectively. Culture recovery of N.gonorrhoeae was only possible in 15.8% of throat swabs, but was successful in 61.9% of anorectal and 84.2% of urogenital samples. CONCLUSIONS: Asymptomatic pharyngeal gonorrhoea is common. Gargle samples should be used only as alternative specimens with inferior sensitivity compared to throat swab samples.
ABSTRACT
Purpose: Determining the relationship between the use of types of psychoactive substance and risky sexual behavior among men. The sources cited in the manuscript were selected through a search of scientific article databases in July 2023. Priority was given to publications with release dates from 2018-2023. Publications in Polish and English were included. Views: The phenomenon of chemsex, more and more often noted in the group of men who have sex with men (MSM), involving sexual activity under the influence of intoxicants, promotes risky sexual behavior. The drugs used for these practices are mainly stimulants, disinhibitors and anesthetics. Factors that increase the risk of an individual deciding to engage in chemical sex include not accepting his sexual preferences, feelings of guilt, personality traits characterizing a person prone to taking risks and with a tendency to seek sensations, as well as high scores on the scale of depressiveness. The main factor determining the emergence of the problem is the occurrence of minority stress. Conclusions: There is a relationship between the use of a certain type of psychoactive substance and engaging in risky sexual behavior. Psychoactive substances help to overcome fear and reduce the impact of minority stress on MSM. Risky behaviors undertaken during chemsex include increasing the risk of contracting diseases through the lack of appropriate safeguards, the risk of addiction, prostitution, as well as threats social relationships and mental health.
