Background/Objectives: Chemsex is defined as the intentional use of psychoactive substances to enhance or prolong sexual activity, predominantly observed among men who have sex with men. It has emerged as a notable behavioral and public health concern due to its association with high-risk sexual practices, psychiatric morbidity, and somatic complications. Despite increasing recognition, global prevalence estimates vary widely (3–52.5%) due to differences in study populations and methodology. Commonly used substances include synthetic cathinones, amphetamines/methamphetamines, MDMA, GHB/GBL, ketamine, alkyl nitrites, and PDE-5 inhibitors. Methods: A narrative review was conducted using PubMed through 11 December 2025. Search terms combined chemsex-related terminology, substance names, and health outcomes. Recent English-language publications (2020–2025) were prioritized. Evidence was synthesized thematically across epidemiology, health complications, motivations, and interventions. Results: Chemsex is strongly associated with unprotected sex, multipartner encounters, and prolonged intercourse, leading to significantly increased rates of HIV, syphilis, gonorrhoea, and chlamydia. Psychiatric complications include depression, anxiety, compulsive sexual behavior, and psychosis, with higher risks in individuals engaging in slamming or polysubstance use. Somatic complications vary by substance and include cardiovascular disease, hyponatremia, rhabdomyolysis, ulcerative cystitis, methemoglobinemia, and overdose. Motivational factors extend beyond sexual enhancement and include minority stress, internalized and externalized stigma, and maladaptive coping mechanisms. Integrated interventions combining harm reduction, cognitive–behavioral therapy, peer-led services, and pharmacotherapy, alongside digital health tools to support PrEP adherence and risk reduction, show promise in mitigating these harms. Conclusions: Chemsex represents a complex interplay of biological, psychological, and sociocultural factors that contribute to elevated STI risk and psychiatric and somatic morbidity. Addressing chemsex requires destigmatized, multidisciplinary approaches that integrate behavioral, pharmacological, and community-based interventions. Digital health innovations can further enhance engagement, risk reduction, and access to timely care.

Background/Objectives: This study investigates the potential association between the sharp increase in syphilis cases in Japan and the growing popularity of dating apps, with a specific focus on the dynamics during the COVID-19 pandemic. Syphilis, a sexually transmitted infection (STIs) caused by Treponema pallidum, presents a significant global public health challenge despite being curable with antibiotics. In Japan, the incidence of syphilis has risen dramatically since 2013, surpassing 10,000 reported cases annually by 2022. Methods: To examine this trend, we analyzed the quarterly reported syphilis cases alongside active user data from three major dating apps (App1, App2, and App3) and conducted a stratified linear correlation analysis by gender and age group. Results: The results reveal that syphilis cases showed accelerated growth starting in the first quarter of 2021, and App 3 demonstrated the strongest positive correlation with new syphilis cases. The association was particularly significant among males aged 20–29 (R2 = 0.70, p = 0.0007) and 30–39 (R2 = 0.82, p < 0.0001). Conclusions: These findings suggest that the widespread use of dating apps may contribute to the rise in sexually transmitted infections, including syphilis, by facilitating extensive new sexual contacts. Notably, this trend became increasingly evident during the COVID-19 pandemic. Future STI prevention strategies should consider integrating dating apps as a potential medium for public health interventions. Additionally, strengthening sexual health services is essential to ensure that responses to global crises do not inadvertently undermine STI prevention and control efforts.

Background/Objective: High-risk Human papillomavirus (hrHPV) is the leading cause of premalignant lesions and cervical cancer (CC), affecting disproportionally women living with HIV. Mozambique is among the countries with a heavy triple-burden of HIV, hrHPV infections and CC which accounts for more than 5300 new cases and 3800 deaths each year. In this study, we assessed the age-specific distribution and factors associated with hrHPV and cervical lesions among HIV-positive and -negative women from HPV-ISI (HPV Innovative Screening Initiative) study in Maputo, Mozambique. Methods: This cross-sectional study included 1248 non-pregnant women aged ≥18 years who attended CC screening at the DREAM Sant’Egídio Health Centre between July 2021 and April 2022. Screening involved visual inspection with acetic acid (VIA) and high-risk HPV DNA testing. Sociodemographic, lifestyle, and reproductive data were collected through a routine questionnaire. Logistic regression assessed associations between risk factors and hrHPV infection or cervical lesions. Age-specific hrHPV prevalence, partial HPV16/18 genotyping, and abnormal cytology rates were further analyzed by HIV status. Results: The mean age of participants was 43.0 ± 8.6 years. Overall hrHPV prevalence was 28.0%, being higher among HIV-positive women (46.8%) than HIV-negative women (23.8%). Non-16/18 hrHPV genotypes predominated across all age groups. VIA positivity was 11.1%, most frequently involving less than 75% of the cervical area and was more common among younger women (30–45 years) and those living with HIV. Increasing age was associated with lower odds of hrHPV infection (OR = 0.98, 95% CI: 0.97–1.00; p = 0.017), as was higher parity (≥3 deliveries vs. nulliparity: OR = 0.58, 95% CI: 0.36–0.94; p = 0.029). Contraceptive use (OR = 1.65, 95% CI: 1.15–2.38; p = 0.007) and a partially or non-visible squamocolumnar junction (SCJ) (OR = 2.88, 95% CI: 1.74–4.79; p < 0.001) were associated with higher odds of VIA positivity. Conclusions: hrHPV infection and cervical lesions were more frequent in younger and HIV-positive women, highlighting the need for strengthened targeted screening within HIV care services in Mozambique.

Background: In Bangladesh, a number of sex workers are involved in commercial sex work in different brothels in both legal and illegal settlements due to reasons such as lack of social support, depression, forced sex, abuse, violence, polyamory, being kidnapped, and unemployment. In this study, we tried to evaluate the demographic characteristics and prevalence of viral and sexually transmitted diseases (STDs) among the study population. Methods: A total of 250 female sex workers were interviewed and tested from the Daulatdia brothel of Rajbari district, Bangladesh, who had been working there for at least 1 month. Through questionnaires, demographic data were collected. Primarily, lateral flow immunoassay (LFIA) tests were used to investigate HCV (Hepatitis C Virus), HBV (Hepatitis B Virus), and Syphilis, which were reconfirmed using enzyme-linked immunosorbent assay (ELISA) in cases of positive results. Results: The mean age was 27.51 ± 6.69 years with a range of 18–50 years. Most of them (n = 243, 97.98%) had elementary knowledge of STDs. We determined that overall, 96 (38.40%) were positive for either of these diseases. Individually, 10 (4.00%), 18 (7.20%), and 68 (27.20%) were positive for HCV, HBV, and syphilis, respectively. Conclusions: Our observation indicates that females of all ages should be strictly protected from forced sex work. Current sex workers should be educated regarding the dangers and protective mechanisms of STDs. In addition, as a public health concern, regular clinical check-ups and STD associated diagnoses are necessary to ensure the safety of FSW from these highly infectious and concerning diseases. Due to their socio-economic condition, proper treatment and rehabilitation are highly recommended.

Background: HIV is one of the deadliest viruses in the world and the leading cause of mortality and morbidity in the Sub-Saharan African countries, including Ethiopia. Millions of new HIV infections are reported every year among the population in the 15–24 age group. Particularly, adolescents are vulnerable to HIV infection due to a lack of adequate information and engagement in risky sexual practices. Thus, the assessment of knowledge, attitudes, and practices (KAPs) is one of the cornerstones in the fight against HIV/AIDS for designing appropriate prevention strategies. This study aimed to assess the KAPs regarding HIV/AIDS among high school students in Burayu town, Ethiopia. Methods: A cross-sectional study design was conducted on students from three higher secondary schools in Burayu town from February to June 2022. A total of 394 students were selected using a stratified proportional sampling technique. Data were collected using pre-tested and self-administered questionnaires and analyzed by SPSS version 26. Descriptive statistics were conducted, and logistic regression was used to determine the associations between variables. A p-value ≤ 0.05 was considered significant in all cases. Results: Out of the 394 students, the majority of respondents (70%) had sufficient knowledge about HIV/AIDS transmission and prevention, while only 61% demonstrated a positive attitude towards people living with HIV/AIDS (PLWHA). In bivariate analysis, a higher level of knowledge was significantly associated with a positive attitude towards PLWHA at OR 23.4, 95% CI, 2.9–185.5, p = 0.003, and not having had sexual practice at OR 4.1, 95% CI, 1.2–13.9, p = 0.025. In multivariate analysis, sexual practice was significantly (p ≤ 0.05) associated with the level of knowledge, age, gender, and places of residence at AORs values of 5.5, 9.7, 3.4, and 5.5, respectively. Conclusions: This study suggests that students with high levels of knowledge had a positive attitude towards PLWHA and less sexual practice compared to students with low levels of knowledge. Furthermore, students’ sexual practice was significantly associated with knowledge level, age, gender, and place of residence. This underscores the urgent need for targeted education to empower vulnerable groups, foster positive attitudes and practive, and curb HIV/AIDS transmission for improved health outcomes.

Background: Oral manifestations are common among people living with HIV (PLWH) and serve as important clinical indicators of immune status and disease progression. Despite extensive global research, data from the Gulf Cooperation Council region, particularly Saudi Arabia, remain limited. Aims: In this study, we aimed to determine the prevalence of oral manifestations, and their associations with immunological parameters, in a large cohort of PLWH in the Eastern Province of Saudi Arabia. Methods: In this cross-sectional study, we enrolled 1500 adult PLWH who attended the Dammam Medical Complex HIV Clinic between January and December 2023. Demographic, clinical, and laboratory data were collected through medical record review. Standardized oral examinations were performed once per participant by two calibrated dentists using World Health Organization criteria. Statistical analyses included descriptive statistics, chi-square tests, and independent t-tests, with significance set at p < 0.05. Results: The cohort had a mean age of 38.3 ± 11.5 years and was predominantly male (78.3%). Most patients (89.6%) were receiving antiretroviral therapy (ART), with 75.7% achieving viral suppression. The mean CD4 count was 527 ± 221 cells/μL. Common co-infections included hepatitis C virus (11.7%), tuberculosis (17.2%), and hepatitis B virus (4.3%). The prevalence of any HIV-related oral manifestation was 72.9% (n = 1093); the most common findings were xerostomia (subjective dry mouth sensation, 48.1%), oral candidiasis (21.6%), and periodontitis (42.7%). Among severely immunosuppressed patients (CD4 < 200 cells/μL, n = 114), 89.5% had oral manifestations, with oral candidiasis affecting 66.7%. Severe immunosuppression was strongly associated with ART-naive status (92.0% vs. 8.0%, χ2 = 864.55, p < 0.001). The presence of HIV-related oral manifestations was significantly associated with CD4 count < 200 cells/μL (χ2 = 15.96, p < 0.001). Conclusions: HIV-related oral manifestations remain highly prevalent in our large Saudi cohort, despite high ART coverage, with xerostomia and oral candidiasis as the predominant findings. Severe immunosuppression was strongly associated with both ART-naive status and opportunistic oral infections. The association between oral manifestations and immunosuppression underscores their continued clinical relevance as accessible indicators of disease status. Integration of routine oral health screening into HIV care is essential for comprehensive patient management in the region.

Background: Syphilis, a major sexually transmitted infection, may contribute to cardiovascular complications, impacting hospital outcomes and costs. This study evaluates the association between syphilis burden and hospitalization outcomes (cost, length of stay, and aneurysm mortality) across Brazilian regions from 2010 to 2024. Methods: Using Brazil’s national healthcare database (n = 405 state-year observations), we classified states by syphilis burden (high, low, intermediate) based on hospitalization rates. Outcomes included average hospitalization cost (R$), length of stay (days), and aneurysm mortality rate (per 100,000). Descriptive statistics, non-parametric tests, ANCOVA models adjusted for hospital complexity and year, and sensitivity analyses (alternative thresholds, outlier removal) were conducted. Regional trends and economic impacts were assessed. Results: High syphilis burden was associated with shorter hospital stays (β = 2.11, p = 0.0008, Cohen’s d = −0.484, power = 0.937) but not with cost (β = 37.6, p = 0.758) or mortality (β = −0.077, p = 0.951). Syphilis incidence correlated moderately with hospitalizations (r = 0.422) but not with aneurysm mortality (Spearman ρ = −0.065, p = 0.193). Total costs (2010–2024) were R$17.7 M (high burden), R$1.9 M (low), and R$12.0 M (intermediate). Regional analyses revealed significant interactions in Nordeste and Norte for length of stay (p = 0.013–0.033). Sensitivity analyses confirmed robustness (Adjusted R2 = 0.049–0.273). Conclusion: High syphilis burden is linked, ecologically, to reduced hospital stays, potentially reflecting fewer complex cases, with substantial economic costs. Regional disparities highlight the need for targeted STI prevention. These findings inform health policy to mitigate syphilis-related hospital burdens in Brazil.

Background/Objective: High-risk human papillomavirus (hrHPV) is an established causative agent for the malignant transformation of cervical cells that can be detected using the Papanicolaou (Pap) smear test. A call by the World Health Organization (WHO) for global collective efforts towards eliminating cervical cancer has endorsed hrHPV DNA testing as an alternative screening test. The objective of this study was to determine the diagnostic utility of hrHPV DNA testing in detecting high-grade cervical intraepithelial lesions (HSILs) in unvaccinated women with abnormal Pap smears and histopathologically confirmed CIN3 and carcinoma. Methods: This study included 111 cervical tissues with a histopathological confirmation of the cervical intraepithelial neoplasia grade (CIN3) and malignancy. Tissues were sectioned, dewaxed, and digested, and DNA was extracted and tested for hrHPV using the Abbott RealTime HR HPV assay. Pap smear results associated with the tissue samples were extracted from corresponding clinical records, and data was analyzed using R-statistical software. Results: Extracted Pap smear records for the 111 cervical tissue samples indicated that 89 (80.2%) had a high-grade intraepithelial lesion (Pap-HSIL), 20 (18%) had squamous cell carcinoma (Pap-SCC), and two (1.8%) had Pap-adenocarcinoma. A total of 68/89 (76.4%) of Pap-HSIL, 15/20 (75%) of Pap-SCC, and ½ (50%) of Pap-adenocarcinoma cases had detectable hrHPV DNA. Conclusions: This study’s findings demonstrate that the Pap smear is still a valuable screening test especially for detecting both hrHPV-dependent and -independent cervical dysplasia in unvaccinated populations. While considerations are made to improve cervical cancer screening, including the introduction of hrHPV DNA testing in national cervical cancer screening programs, there is a need for the careful interpretation of molecular testing results for clinical intervention. This is especially important for hrHPV-independent cervical dysplasia screening, since this can have dire implications for clinically asymptomatic women.

Background: The increasing prevalence of antibiotic-resistant Mycoplasma genitalium poses a significant challenge to global public health, necessitating the exploration of alternative therapeutic strategies, including vaccine development. Methods: In this study, we employed an immuno-informatics-based reverse vaccinology approach augmented with artificial intelligence-driven tools, to identify and characterize potential B-cell and T-cell epitopes from the hypothetical proteins (HPs) retrieved from the genome of the MG_G37T strain, a previously uncharacterized yet promising vaccine target. Using multiple softwares, a systematic pipeline was utilized to assess the sub-cellular localization, antigenicity, and allergenicity of the selected proteins. Results: Sub-cellular localization analysis identified the presence of several outer membrane and extracellular proteins in the genome of MG_G37T, indicating their surface association and accessibility to immune surveillance. Antigenicity and allergenicity prediction tools led to the identification of two top-scoring hypothetical proteins (fig|2097.71.peg.1 (UniProt ID: P22747) and fig|2097.70.peg.33 (UniProt ID: Q57081)) that demonstrated strong antigenic potential, non-allergenic properties, and suitability as vaccine candidates. Epitope mapping and structural modeling analyses further validated the immunogenic potential of these epitopes, highlighting their ability to interact with host immune components effectively. Comparative analyses with mouse allelic regions indicated the potential translational relevance of these predicted epitopes for preclinical studies. Conclusions: In particular, this study highlights the potential of these two hypothetical proteins as a promising vaccine candidate and provides a strong reason for experimental validation towards the design and development of effective vaccines to combat M. genitalium infections in the era of antimicrobial resistance.

Background: There is an urgent need for novel treatment options for Neisseria gonorrhoeae. Methenamine is an interesting urinary antiseptic with a very low propensity to induce antimicrobial resistance. Methods: We assessed the MICs of methenamine-hippurate for 18 N. gonorrhoeae isolates. We then assessed the in vivo efficacy of methenamine-hippurate against N. gonorrhoeae using the Galleria mellonella infection model. Results: We found that all the gonococcal isolates had a methenamine-hippurate MIC of 300 mg/L. This MIC was not higher in isolates with higher ceftriaxone MICs. No toxicity of methenamine at the doses tested was found, and doses as low as 200 mg/kg were effective in the G. mellonella model. Conclusions: Further studies in mice and humans are required to assess if methenamine-hippurate could be used to treat gonococcal urethritis alone or in combination with other agents such as ceftriaxone.

Background/Objectives: Mycoplasma and Ureaplasma species are pathogens commonly associated with urogenital infections in sexually active individuals. Despite their clinical relevance, these organisms are less frequently studied than other sexually transmitted infections (STIs), leading to limited data on their antimicrobial susceptibility and resistance profiles. This study aimed to characterize the antimicrobial susceptibility and resistance patterns of Mycoplasma hominis and Ureaplasma spp. among individuals in Salvador, Bahia, Brazil, and to identify the potential associated risk factors. Methods: We conducted a retrospective descriptive study during 2022–2024 using secondary data obtained from the SMARTLab® diagnostic system. Sociodemographic and epidemiological data, along with results from IST2 and IST3 diagnostic tests, were analyzed. Absolute and relative frequencies were calculated by sex, age group, and antimicrobial susceptibility profile. Results: Our results revealed a predominance of M. hominis and Ureaplasma spp. infection among women (98.5%), and in individuals aged 38 to 47 years. Ureaplasma spp. accounted for the majority of positive cases. High rates of resistance were observed in the IST2 test, with 75.0% of M. hominis and 84.1% of Ureaplasma urealyticum resistant to ciprofloxacin. In the IST3 test, Ureaplasma spp. demonstrated a 7.3% resistance rate to levofloxacin, which increased to 22.2% in cases of co-infection. Conclusions: These findings underscore the growing threat of antimicrobial resistance in Mycoplasma and Ureaplasma species and highlight the need for targeted public health strategies and diagnostic tools to manage infections caused by these organisms, particularly in high-risk populations.

Background/Objectives: An optimal approach to addressing oral antiretroviral therapy (ART) adherence remains unclear in the research literature. This review aimed to identify definitions and thresholds of adherence, proposed methods and frequencies of evaluating adherence levels, barriers to adherence, and interventions to address adherence problems. Methods: A scoping review of HIV guidelines drew on guidance from the Joanna Briggs Institute. Eligible English and French guidelines and their updates concerned adults with HIV and oral ART from developed countries and international health organizations from 2017 to May 2023. Three databases were systematically searched, along with the gray literature. Then, a targeted search for omitted developed countries was conducted. Document selection and data charting were performed with two reviewers for 20% of records and full texts, followed by an independent review. Inductive–deductive content analysis of extracted data was performed using NVivo 14 software. Results: Twenty-four guidelines were identified from seven countries and two international health organizations. Only two defined ART adherence, and none offered a threshold for adequate adherence. Most guidelines (n = 22/24) reported adherence interventions, 20 guidelines (83%) identified adherence barriers, 20 guidelines (83%) noted variable methods to evaluate adherence, and 17 guidelines (71%) proposed a range of frequencies for assessing adherence. Conclusions: This review underscored a lack of consensus around adherence and its management. Very few guidelines defined adherence, none proposed an optimal threshold, and there was no agreement on how to gauge adherence. These gaps and variability raise questions about how clinicians manage adherence in practice. More systematic and preventative approaches to monitoring adherence may be needed.

Multidrug-resistant (MDR) Mycoplasma genitalium (M. genitalium) presents a significant risk of treatment failure in many sexually transmitted infections (STIs) and can result in persistent and recurrent urethritis or cervicitis. This case report describes a recurrent M. genitalium urethritis resistant to sulfamethoxazole-trimethoprim (TMP-SMX), doxycycline, and moxifloxacin. The infection was ultimately cured after both the removal of a nidus of infection and through the use of Lefamulin. Lefamulin is a novel agent approved for use in community-acquired bacterial pneumonia and bacterial skin infections that may be useful in difficult sexually transmitted infections. Background/Objectives: Deciding whether or not to treat M. genitalium can be challenging as it can be a colonizer, or present with a symptomatic pathogen, and even if it is causing symptoms, it can be drug-resistant. Our objective here is to highlight important considerations on whether or not to treat and, if so, what options exist. Conclusions: In a world of increasing drug-resistant STIs, this case highlights the challenges of managing MDR M. genitalium and how foreign bodies can allow reoccurrence. Also highlighted in this case, Lefamulin appears to be a viable alternative line of treatment of MDR M. genitalium that defies other first-line antibiotics.

Background/Objectives: In Mexico, there is very little data on the prevalence of metabolic syndrome in people living with human immunodeficiency virus (HIV) receiving antiretroviral therapy (ART), so, determining the number of people with this condition will help to establish measures to treat it promptly. Methods: A descriptive, observational, prospective, cross-sectional study was conducted in a cohort of people living with HIV who signed the informed consent form and were stratified according to the criteria established by the Adult Treatment Panel III (ATP-III) and the Latin American Diabetes Association (ALAD) for the diagnosis of metabolic syndrome. Results: According to the ATP-III and ALAD criteria, 26.5% and 36.3% of people living with HIV receiving ART were diagnosed with metabolic syndrome, respectively. Metabolic syndrome was more prevalent in men than in women, using both classification criteria (ATP-III: 58 men [67.4%] vs. 28 women [32.6%]; ALAD: 84 men [71.2%] vs. 34 women [28.8%]). The median time since HIV diagnosis of the participants with metabolic syndrome was longer than for the participants without metabolic syndrome, using the ALAD criteria (p = 0.023). The time spent on ART among participants with metabolic syndrome was longer than among those without, using the ATP-III criteria (p = 0.011). The CD4+ T-cell count and HIV-RNA detection showed no significant difference between participants with and without metabolic syndrome (p > 0.05). No statistical significance was found concerning ART and metabolic syndrome; it is noteworthy that for participants with dolutegravir/abacavir/lamivudine (DTG/ABC/3TC), the frequency was similar regardless of the criteria used, and different for those who were taking bictegravir/emtricitabine/tenofovir alafenamide (BIC/FTC/TAF) or were in other schemes (etravirine, darunavir/ritonavir, raltegravir). Conclusions: Our results suggested that 26.5% and 36.3% of the people living with HIV receiving ART included in this study had metabolic syndrome according to ATP-III and ALAD criteria, respectively. These results are consistent with results reported in the Latin American population. Interestingly, both criteria showed a higher frequency of metabolic syndrome in men living with HIV compared to women.

Background/Objectives: The recent Executive Order suspending the United States Agency for International Development (USAID) programmes, including Development Assistance for Health (DAH), has sparked serious debates about the sustainability of ongoing HIV/AIDS control programmes, particularly in Africa. In this study, we examined HIV/AIDS-specific DAH allocation to Africa from 1990 to 2022, and the potential effects of funding cutbacks on disease outcomes. Methods: We nested 54 countries within five sub-regions of Africa and applied linear mixed-effects models to estimate the effects of DAH on HIV/AIDS incidence and mortality rates, accounting for clustering by sub-region and potential variability due to baseline incidence and mortality and other sources of heterogeneity. Results: Total DAH allocated to Africa increased from US$534,343 in 1990 to US$5,273,264 in 2022. The United States (U.S.) public sector contributed nearly two-thirds (US$58,399,088; 63.01%) of the total funding. Most of these funds were disbursed to Southern and Eastern Sub-Saharan Africa (SSA), particularly countries with the highest HIV/AIDS burdens, including South Africa and Kenya. The fixed effects results and predicted margins indicate that, in addition to having a direct effect, U.S. public sector-specific DAH moderates the effectiveness of other international donor funding and domestic general government health spending (GHES) on HIV/AIDS incidence and mortality. Conclusions: Based on the historical trends and funding interactions, the cutback in U.S. DAH could be associated with weakening of the overall effectiveness of other donor funding and GHES. However, any future effects are contingent on African countries’ resilience to evolving challenges and resource allocation.

Forced displacement exacerbates health vulnerabilities, particularly regarding HIV prevention, diagnosis, and treatment. Refugees often experience heightened exposure to HIV due to precarious living conditions, sexual violence, and healthcare access barriers. Background: Structural inequalities, legal precarity, and stigma hinder HIV care for refugees, especially in resource-limited settings. Excluded from national health programs, refugees often depend on underfunded humanitarian aid. Cultural stigma, limited awareness, and mobility constraints further heighten their vulnerability. Methods: This study draws on a review of peer-reviewed articles, policy documents, and case studies from refugee-hosting countries. It examines healthcare access, service provision gaps, and policy responses to HIV among displaced populations. Results: The article highlights systemic barriers to HIV services, including inadequate testing, inconsistent treatment availability, and cultural barriers to care. Policy frameworks often fail to integrate refugees into national HIV programs, exacerbating health disparities. Conclusions: The exclusion of refugees from national healthcare, compounded by stigma and mobility constraints, deepens health disparities and heightens HIV transmission risks. Without targeted interventions and inclusive health systems, refugees face disproportionate HIV-related morbidity, endangering broader public health in host communities.

Background/Objectives: Syphilis diagnosis in Armenia is unreliable due to inconsistent testing methods, limited access to confirmatory tests, and the underutilization of healthcare services due to stigma and lack of awareness. In 2022, 29% of cases were latent, 8.1% were late latent, 21% were secondary, and 1% were congenital. We assessed primary care physicians’ (PCPs) knowledge, attitudes, and practices regarding syphilis diagnosis and prevention to improve early detection. Methods: Between December 2023 and February 2024, we conducted a cross-sectional survey among outpatient physicians. We randomly selected 24 clinics in six regions. In each clinic, we randomly selected respondents from employee registries. We assigned one or two points to correct answers and zero points to incorrect or unknown answers; scores were categorized as Poor (0–<30%), Moderate (30–<70%), and Good (>70%). We used non-parametric tests to compare groups. Results: Of the 413 physicians contacted, 345 (83%) responded; 74% were female; the median age was 46 years; 54% had > 16 years work experience; and 47% worked as general practitioners. The respondents had moderate knowledge of risk groups (56%) and symptoms (49%) and poor knowledge of disease transmission (8%). As for practices, the respondents expressed difficulty in prescribing additional laboratory tests based on clinical symptoms (51%) and struggled with reporting diagnosed syphilis cases (66%); moderate opinions on pregnancy termination decisions (65%) were conveyed. The respondents’ knowledge did not correlate with their practice (r = 0.23) and attitude (r = 0.25) scores. Conclusions: PCPs’ knowledge was not positively associated with improved practices and attitudes regarding syphilis diagnosis and prevention. This highlights the need to improve healthcare workers’ post-graduate education and implement an efficient screening program to detect and treat asymptomatic, late latent, and congenital infections, as well as to prevent complications, transmission, and reinfection.

Sub-Saharan African (SSA) women experience a high prevalence of HIV, sexually transmitted infections (STIs), and unintended pregnancies, necessitating effective, integrated prevention strategies. Multipurpose prevention technologies (MPTs) offer a promising approach to address these overlapping health concerns by providing single products that simultaneously prevent HIV, other STIs, and/or unintended pregnancies. Given the persistent sexual and reproductive health (SRH) challenges faced by women in SSA, in this opinion piece, we explore practical considerations for MPT adoption and scale-up within the region. With this opinion article, we discuss the data on MPT development and identify key factors for successful MPT implementation in SSA. We examine the current MPT pipeline, product features, regulatory challenges, and structural, individual, and community barriers that impact MPT acceptance and usage among SSA women. Successful MPT uptake hinges on designing discreet, user-controlled products and engaging end-users, healthcare providers, and communities in product development and promotion. Structural factors such as robust supply chains, regulatory clarity, and financial support are also essential. Addressing socio-cultural norms, especially partner consent, and strengthening demand creation through community-driven, culturally sensitive strategies are critical for scaling MPTs. In conclusion, MPTs represent a transformative opportunity to reduce the burden of HIV, STIs, and unintended pregnancies in SSA. Strategic, culturally attuned approaches are essential to ensure the acceptability and accessibility of MPTs. Expedited pathways for regulatory approval, collaborative partnerships, and community-centered demand creation will be vital to realize the full potential of MPTs in advancing women’s SRH in SSA.
