Effectiveness of eHealth interventions for HIV prevention, testing and management: An umbrella review.

Human immunodeficiency virus (HIV) infection has become a major contributor to the global burden of disease. Globally, the number of cases of HIV continues to increase. Electronic health (eHealth) interventions have emerged as promising tools to support disease self-management among people living with HIV. The purpose of this umbrella review is to systematically evaluate and summarize the evidence and results of published systematic reviews and meta-analyses on the effectiveness of eHealth interventions for HIV prevention, testing and management. PubMed, Embase and the Cochrane Library were searched for reviews. The methodological quality of the included studies was assessed using AMSTAR-2. A total of 22 systematic reviews were included. The methodological quality of the reviews was low or critically low. EHealth interventions range from Internet, computer, or mobile interventions to websites, programs, applications, email, video, games, telemedicine, texting, and social media, or a combination of them. The majority of the reviews showed evidence of effectiveness (including increased participation in HIV management behaviours, successfully changed HIV testing behaviours, and reduced risk behaviours). EHealth interventions were effective in the short term. Ehealth interventions have the potential to improve HIV prevention, HIV testing and disease management. Due to the limitations of the low methodological quality of the currently available systematic reviews, more high-quality evidence is needed to develop clear and robust recommendations.

Factors affecting HIV prevention communication between professional nurses and high school learners in eThekwini

Background: Communication within healthcare settings is crucial for a therapeutic relationship between nurse and patient especially in preventing human immunodeficiency virus (HIV) among adolescent girls. The school health programme in South Africa provides an opportunity to provide HIV prevention services among adolescent girls, however, uptake is low and effective communication can address this.Aim: The study’s purpose was to describe factors affecting HIV prevention communication between professional nurses and high school learners in eThekwini Metropolitan Municipality.Setting: The study was conducted in two high schools in eThekwini Metropolitan Municipality.Methods: The study used a qualitative approach and a descriptive research design. A semi-structured interview guide was used to conduct face-to-face interviews with 30 participants after ethical approval from the researchers’ affiliated institution and informed consent from participants or their guardians were obtained. Thematic analysis was used to analyse the data.Results: Participants were aged between 14 years and 17 years. Most (25) participants were female. Three main themes emerged from the study: communication between the school health nurses and high school learners is facilitated by trust, communication is hindered by fear, and infrequent visits by nurses affect communication positively or negatively.Conclusion: Health education on HIV is essential to prevent HIV among adolescent girls. Effective communication between healthcare providers and adolescent girls facilitates such health education.Contribution: The uptake of HIV prevention services by adolescent girls can be improved by communication that facilitates the therapeutic relationship which is founded on trust, with frequent visits by nurses.

Broadly neutralizing antibodies for HIV prevention: a comprehensive review and future perspectives.

SUMMARYThe human immunodeficiency virus (HIV) epidemic remains a formidable global health concern, with 39 million people living with the virus and 1.3 million new infections reported in 2022. Despite anti-retroviral therapy's effectiveness in pre-exposure prophylaxis, its global adoption is limited. Broadly neutralizing antibodies (bNAbs) offer an alternative strategy for HIV prevention through passive immunization. Historically, passive immunization has been efficacious in the treatment of various diseases ranging from oncology to infectious diseases. Early clinical trials suggest bNAbs are safe, tolerable, and capable of reducing HIV RNA levels. Although challenges such as bNAb resistance have been noted in phase I trials, ongoing research aims to assess the additive or synergistic benefits of combining multiple bNAbs. Researchers are exploring bispecific and trispecific antibodies, and fragment crystallizable region modifications to augment antibody efficacy and half-life. Moreover, the potential of other antibody isotypes like IgG3 and IgA is under investigation. While promising, the application of bNAbs faces economic and logistical barriers. High manufacturing costs, particularly in resource-limited settings, and logistical challenges like cold-chain requirements pose obstacles. Preliminary studies suggest cost-effectiveness, although this is contingent on various factors like efficacy and distribution. Technological advancements and strategic partnerships may mitigate some challenges, but issues like molecular aggregation remain. The World Health Organization has provided preferred product characteristics for bNAbs, focusing on optimizing their efficacy, safety, and accessibility. The integration of bNAbs in HIV prophylaxis necessitates a multi-faceted approach, considering economic, logistical, and scientific variables. This review comprehensively covers the historical context, current advancements, and future avenues of bNAbs in HIV prevention.

The Global Impact of HIV: A Comprehensive Review

The Human Immunodeficiency Virus (HIV) has been a significant global health challenge since its discovery in the 1980s, leading to the devastating Acquired Immunodeficiency Syndrome (AIDS). Despite advancements in medical research and antiretroviral therapies, HIV/AIDS remains a pressing public health concern, particularly in resource-limited regions. This comprehensive review provides updated data and scientific insights on the global impact of HIV, shedding light on the current state of the epidemic and the challenges faced in combating it. The review highlights the resurgence of HIV cases in Eastern European countries, such as Ukraine, Estonia, and Latvia, with surprising increases in AIDS cases observed in East Asian countries. However, it is in sub-Saharan Africa that the burden of HIV remains most acute, with high prevalence rates and a significant number of affected individuals. The region requires continued attention and resources to address the complex challenges associated with HIV prevention, treatment, and care. The article delves into the classification and structure of HIV, emphasizing its belonging to the Lentivirinae subfamily, specifically HIV-1 and HIV-2. HIV-1, the predominant viral species globally, exhibits a distinct clinical latency phase, contributing to its persistence and infectivity. The high replication rate and genetic variability of HIV, driven by the error-prone reverse transcriptase enzyme, result in the emergence of diverse subtypes and strains across different regions. Furthermore, the article explores the structural components of HIV-1, including the envelope glycoproteins (gp120 and gp41), matrix protein, and various enzymes critical to the viral life cycle. Despite progress in medical research and access to antiretroviral therapies, HIV/AIDS continues to present challenges such as limited resources, drug resistance, and regional disparities.

Facilitators, Barriers, and Opportunities to Implementing Sexual History Screening and Human Immunodeficiency Virus Pre-Exposure Prophylaxis at a Federally Qualified Health Center.

Sexual history screening (SHS) is recommended to determine risk for acquisition of human immunodeficiency virus (HIV) and eligibility for pre-exposure prophylaxis (PrEP). SHS and PrEP are underutilized, sequential screening, and prevention practices. This study aimed to understand factors impacting the implementation of SHS and PrEP at a multi-site federally qualified health center (FQHC) in Connecticut. Guided by the Consolidated Framework for Implementation Research, semistructured interviews were conducted on Zoom with primary care providers (PCPs), medical assistants, clinical leadership, and PrEP navigators. Convenience and purposive sampling took place via email until thematic saturation was achieved. Thematic analysis was conducted. Twenty-two participants were interviewed for this study. PCPs lacked knowledge and reported limited or no use of SHS to determine patients' level of HIV risk, which may explain why most PCPs relied on patients to request PrEP. While PCPs perceived organizational support to prescribe PrEP, clinical staff were unaware of structural resources. Lastly, participants described a vertical trajectory of influence from external sources (policies and insurance) to time allocated to appointments that limits their ability to implement SHS and PrEP, further complicated by the electronic health record and disparities in structural resources across clinical sites. This study provides foundational evidence for future research on implementation strategies to improve HIV prevention through universal, comprehensive SHS to identify patients for PrEP. Overcoming barriers to SHS and PrEP, particularly in clinical settings such as FQHCs that care for vulnerable populations, may improve identification, prevention, and treatment of HIV and aid in ending the HIV epidemic.

Spatial distribution and determinants of HIV high burden in the Southern African sub-region.

Spatial analysis at different levels can help understand spatial variation of human immunodeficiency virus (HIV) infection, disease drivers, and targeted interventions. Combining spatial analysis and the evaluation of the determinants of the HIV burden in Southern African countries is essential for a better understanding of the disease dynamics in high-burden settings. The study countries were selected based on the availability of demographic and health surveys (DHS) and corresponding geographic coordinates. We used multivariable regression to evaluate the determinants of HIV burden and assessed the presence and nature of HIV spatial autocorrelation in six Southern African countries. The overall prevalence of HIV for each country varied between 11.3% in Zambia and 22.4% in South Africa. The HIV prevalence rate was higher among female respondents in all six countries. There were reductions in prevalence estimates in most countries yearly from 2011 to 2020. The hotspot cluster findings show that the major cities in each country are the key sites of high HIV burden. Compared with female respondents, the odds of being HIV positive were lesser among the male respondents. The probability of HIV infection was higher among those who had sexually transmitted infections (STI) in the last 12 months, divorced and widowed individuals, and women aged 25 years and older. Our research findings show that analysis of survey data could provide reasonable estimates of the wide-ranging spatial structure of the HIV epidemic in Southern African countries. Key determinants such as individuals who are divorced, middle-aged women, and people who recently treated STIs, should be the focus of HIV prevention and control interventions. The spatial distribution of high-burden areas for HIV in the selected countries was more pronounced in the major cities. Interventions should also be focused on locations identified as hotspot clusters.

Safe sex negotiation and HIV risk reduction among women: A cross-sectional analysis of Burkina Faso 2021 Demographic and Health Survey.

Women are biologically more susceptible to the Human Immunodeficiency Virus (HIV) and other sexually transmitted Infections (STIs) because receptive sex is riskier than insertive. Despite condom use being the staple preventive method for HIV infection (over 80% efficacy), in Sub-Saharan African countries like Burkina Faso, a high burden of HIV and the unmet need for condom use coexist. Moreover, even though women in SSA are disproportionately HIV positive, they are reportedly less capable of negotiating condom use for HIV risk reduction. Thus, using the Health Believe Model (HBM), this study explored the factors that influence condom use among women within the context of HIV prevention, with a key interest in condom use negotiation. Using the women's dataset of the 2021 Burkina Faso Demographic and Health Survey and applying logistic regression models, this study examined the factors associated with condom use for HIV risk reduction. Women who had confidence to negotiate condom use with their partners (OR = 1.57, P<0.001, 95%CI: 1.29, 1.91), those with secondary education (OR = 1.38, P<0.05, 95%CI: 1.07 1.77), from richest households (OR = 1.64, P<0.05, 95%CI: 1.08, 2.47), the employed (OR = 1.23, P<0.05, 95%CI: 1.02, 1.49), women with knowledge of sexually transmitted infections (OR = 1.58, P<0.001, 95%CI: 1.26, 1.97), those who have ever been tested for HIV (OR = 1.85, P<0.001, 95%CI: 1.52 2.24), as well as those who knew that a healthy-looking person can have HIV (OR = 2.64, P<0.001, 95%CI: 2.15, 3.24) were all significantly more likely to practice condom use for HIV risk reduction. Also, religion and geographical location of participants significantly predicted condom use for HIV risk reduction in the study context. The ability to negotiate condom use, knowledge of HIV and STIs, the socioeconomic status of women, as well as their geographical location, influence their practice of safer sex for HIV risk reduction in Burkina Faso.

Perceptions and Acceptance of a Prophylactic Vaccine for Human Immunodeficiency Virus (HIV): A Qualitative Study.

Despite advances in human immunodeficiency virus (HIV) prevention methods, such as the advent of pre-exposure prophylaxis (PrEP), the number of people with newly acquired HIV remains high, particularly in at-risk groups. A prophylactic HIV vaccine could contribute to reduced disease prevalence and future transmission and address limitations of existing options, such as suboptimal long-term adherence to PrEPs. This qualitative study aimed to capture perceptions towards and acceptance of prophylactic HIV vaccination in three adult populations in the United States: the general population, 'at-risk' individuals (e.g. men who have sex with men, transgender individuals, gender-nonconforming individuals, and individuals in a sexual relationship with a person living with HIV), and parents/caregivers of children aged 9-17years. Interviews were conducted with 55 participants to explore key drivers and barriers to HIV vaccine uptake, and a conceptual model was developed. The sample was diverse; participants were 51% female, aged 20-57 years (mean 37years), 33% with high school diploma as highest education level, and identified as White (42%), Black or African American (35%), of Hispanic, Latino, or Spanish origin (22%), or other races/ethnicities (8%) [groupings are not mutually exclusive]. Perceptions were influenced by individual, interpersonal, community, institutional, and structural factors. Overall, 98% of participants thought vaccination would be beneficial in preventing HIV. Key considerations/barriers included perceived susceptibility, i.e. whether participants felt there was a risk of contracting HIV (discussed by 90%); the clinical profile of the vaccine (e.g. the adverse effect profile [98%], and vaccine efficacy [85%], cost [73%] and administration schedule [88%]); and concerns around potential vaccine-induced seropositivity (VISP; 62%). Stigma was not found to be an important barrier, with a general view that vaccination status was personal. Participants in the 'at-risk' group were the most likely to accept an HIV vaccine (70%). Unique concerns in the subgroups included how a potential vaccine's clinical profile compared with PrEP, voiced by those receiving/considering PrEP, and considerations of children's views on the topic, voiced by parents/caregivers. Understanding these factors could help develop HIV vaccine research strategies and contribute toward public health messaging to support future HIV vaccination programs.

Socio-demographic correlates of knowledge, perceived risk and uptake of HIV testing among Nurses in Osogbo, South-western Nigeria.

Introduction: Human Immunodeficiency Virus (HIV)testing is a crucial step in the prevention and control of HIV. Nurses, as primary healthcare providers, play a vital role in promoting HIV testing service and providing accurate information to patients. This study assessed the sociodemographic correlates of HIV knowledge, perceived risk and uptake of HIV testing among nurses in Osogbo.Methods: This was a cross-sectional study design using multistage sampling method for selection of 220 nurses from both private and public health facilities in Osogbo. Data was collected using a semi-structured self-administered questionnaire and IBM SPSS version 23 was used for data analysis.Results: The knowledge of HIV/AIDs was good among the respondents (74.4%), 63.6% of the respondents had perceived high-risk of contracting HIV while 89.3% had uptake HIV testing service. Statistical significance was found with nurses in private hospitals who were more knowledgeable on HIV/AIDs than those who work in a public hospital (x2= 4.136, P= 0.042), none of the socio-demographic characteristics was statistically associated with perceived high-risk of the disease.Conclusion: The study found that a significant number of respondents had poor knowledge on HIV/AIDS despite being health workers, there was a gap in their perceived risk and a satisfactoryuptake of HIV testing. However, the socio-demographic characteristics that had a statistical relationship with HIV knowledge and uptake of HIV test were facility category and gender

Experiences of the National Post-Exposure Prophylaxis Hotline (PEPline): Occupational PEP consultation needs and trends, 2014 to 2022

The National Clinician Consultation Center operates the Post-Exposure Prophylaxis Hotline (PEPline), a federally-funded educational resource providing bloodborne pathogen exposure management teleconsultation to US clinicians. Sixty-seven thousand one hundred nine occupational post-exposure prophylaxis (PEP) consultations (January 2014 to December 2022) were retrospectively analyzed to describe PEPline utilization and common inquiries addressed by National Clinician Consultation Center consultants. Most calls involved percutaneous incidents (70%); blood was the most common body fluid discussed (60%). Inpatient units were the most common exposure setting (35%) and licensed nursing professionals were the most common category of exposed workers (28%). Of 2,295 calls where workers had already initiated PEP for human immunodeficiency virus (HIV) prevention and time to first dose was known, 9% had initiated HIV PEP within 2hours of exposure; almost 80% had initiated HIV PEP between 2 and 24hours; 3% after 24 to 36hours; 5% after 36 to 72hours; and 2% after 72hours. Calls from urgent care providers increased by 10% over time. Overall, more than 90% of callers requested support on risk assessment, including source person testing; other common questions involved PEP side effects and follow-up care. PEPline consultations can help raise awareness about PEP availability and timely initiation, and reduce stigma by addressing common misperceptions about bloodborne pathogen transmission mechanisms and likelihood, particularly regarding HIV.

Uptake and challenges with daily oral pre-exposure prophylaxis among men who have sex with men and transgender women, suburban Yangon, Myanmar.

Pre-exposure prophylaxis (PrEP) is effective for human immunodeficiency virus (HIV) prevention in risk groups. We assessed PrEP uptake and 12-month retention among men who have sex with men (MSM) and transgender women (TGW) in Myanmar during the coronavirus disease 2019 pandemic and a political crisis. Using prospectively collected data, we assessed the proportion of persons eligible, initiated and retained 12months on PrEP. We calculated HIV and syphilis incidence among those initiated on PrEP. Predictors of compliance to scheduled visits were assessed with fractional logistic regression. Among 652 persons screened between July and December 2020, 85.3% were eligible and 38.8% initiated PrEP. The daily pill burden was the main reason (86.5%) for refusing PrEP. A history of HIV post-exposure prophylaxis (PEP) and having an HIV-positive partner not on anti-retroviral therapy (ART) was associated with PrEP uptake (p<0.05). The 12-month retention among those initiating PrEP was 43.0%. Age ≥25y, a history of PEP and having an HIV-positive partner not on ART predicted better compliance with scheduled visits (p<0.05). HIV incidence among PrEP initiators was 3.1 per 100 person-years (95% confidence interval [CI] 1.3 to 7.4) and syphilis incidence was 17.6 per 100 person-years (95% CI 12.3 to 25.1). A PrEP program for MSM and TGW in Myanmar was implemented successfully under difficult circumstances. Alternative strategies are needed addressing PrEP uptake and retention.

Co-designing strategies to implement long-acting injectable PrEP for sexual minority men in Chicago: a study protocol for an innovation tournament and implementation mapping

BackgroundParticipatory design approaches can improve successful selection and tailoring of implementation strategies by centering the voices of key constituents. To reduce incidence of the human immunodeficiency virus (HIV) in the USA, co-design of implementation strategies is needed for long-acting injectable cabotegravir (CAB-LA), a new form of HIV pre-exposure prophylaxis, among the disproportionately impacted population of sexual minority men (SMM). This manuscript describes the protocol for participatory design approaches (i.e., innovation tournament and implementation mapping) to inform implementation of CAB-LA among SMM (≥ 12 years), particularly Black and Latino populations, in Chicago.MethodsThis research incorporates innovative methods to accomplish two objectives: (1) to crowdsource ideas for the design of implementation strategies for CAB-LA through a virtual innovation tournament and (2) to leverage the ideas from the innovation tournament to operationalize implementation strategies for CAB-LA thorough the systematic process of implementation mapping. A committee of constituents with diverse expertise and perspectives (e.g., SMM, implementation scientists, HIV clinicians, public health leadership, and community partners) will provide input throughout the design process.DiscussionThis research will produce a menu of co-designed implementation strategies, which can guide plans for CAB-LA integration in Chicago and provide insights for other EHE regions. Further, as the first innovation tournament focused on HIV prevention, this research can provide a framework for participatory approaches across the care continuum. Given that the co-design of implementation strategies often does not involve the participation of individuals with lived experiences, this work will center the voices of those who will benefit most.

Development and validation of the information-motivation-behavioural skills model-based human immunodeficiency virus education kit for adolescents in Malaysia

The growing Human Immunodeficiency Virus (HIV) incidences and insufficient HIV knowledge among Malaysian late adolescents necessitate immediate attention to HIV prevention via education. This study aims to develop and validate an Information-Motivation-Behavioural skills (IMB) model-based education kit for adolescents, PREM-Kit, to educate on HIV prevention among Malaysian late adolescents. Utilizing the Analysis, Design, Development, Implementation, and Evaluation model, we conducted the study in three phases: needs assessment, development of PREM-Kit, and validation of PREM-Kit by applying the IMB model to map the PREM-Kit’s contents. PREM-Kit, developed in Malay language, consisted of an infographic flip chart and videos. Five multi-disciplinary experts validated the PREM-Kit using the content validity index (CVI), and 13 end-users validated the PREM-Kit using the Malay version of the Patient Education Materials Assessment Tool for Printable and Audiovisual Materials. The infographic flip chart comprised three modules covering 15 topics, and an animated video accompanied each module. PREM-Kit achieved CVI scores of 1.0 and median scores of over 80% for understandability and actionability. Overall, the newly developed IMB model-based HIV education kit has good content validity, is simple to comprehend and apply, and is ready for testing its effectiveness in improving adolescents’ knowledge, attitudes, and practices for HIV prevention.

Self-Perception of Risk for HIV Acquisition and Calculated Risk for HIV Acquisition Among Active Duty Air Force Members With Newly Diagnosed HIV Infection.

There have been nearly 1,600 new diagnoses of Human Immunodeficiency Virus (HIV) across the US Armed Forces between 2017 and 2022. While treatment has improved overall survival, self-perception of acquiring HIV may not align with actual risk of acquiring HIV, thus slowing diagnosis and treatment. We aim to evaluate self-perceived risk (SPR) versus calculated risk (CR) of HIV infection in US Air Force (USAF) members with incident HIV diagnosis. All USAF members with new HIV diagnosis evaluated at a specialty care military medical center between January 2015 and March 2020 with case report forms were included (n = 142). SPR was compared to CR using the Denver HIV Risk Score (DHRS). The study was approved by the Army Public Health Center's Public Health Review Board (#14-311) and the Walter Reed Army Institute of Research Human Subjects Protection Branch (#1861E). Patients were predominantly male (98%), with a median age of 26 (IQR 22-30) years, and the majority (85%) reported same-sex partners. Most patients reported a low SPR (n = 78; 55%). A higher proportion of low SPR patients were married or partnered than high SPR patients (29% versus 14%; P = 0.04). Both groups had median DHRS scores in the highest risk category with similar results by reason for HIV screening. The majority of USAF members with incident HIV infection reported a low SPR despite risk factors and CRs identical to high SPR patients. In order to inform HIV prevention strategies in the military, further efforts are needed to educate the military population and providers about HIV risk perception.

Pre-Exposure Prophylaxis for HIV: Bioethical, Clinical, and Epidemiological Considerations

Public health authorities are broadly promoting a strategy known as pre-exposure prophylaxis (PrEP) for the prevention of human immunodeficiency virus (HIV) transmission in the context of high-risk sexual activity and injection drug use. However, there are several limitations to this strategy that are underrecognized. This article reviews the primary literature supporting the use of PrEP and explores the unintended consequences associated with its use. Current public health messaging indicates that PrEP reduces the risk of HIV transmission during sex by 99 percent; however, this figure is based on modeling rather than study findings, and real-world efficacy may be significantly lower. PrEP has been associated with increased rates of sexually transmitted infections, risk compensation, HIV drug resistance, low adherence, and drug side effects. To make fully informed decisions, medical professionals and patients should be aware of these pitfalls. Additionally, this article explores the bioethical implications of prescribing PrEP from a Catholic perspective. Although not always morally illicit, PrEP is most often prescribed in the context of sexual activity outside of marriage between a biological male and female, placing the prescriber in cooperation with activity deemed to be immoral by the Catholic Church. While all medical professionals seeking the common good should aim to reduce the transmission of HIV, not all means are morally licit. Conscience protection for medical professionals opposed to this strategy has become increasingly relevant. Thoughtful discernment is necessary when considering PrEP. Summary: The use of CDC material (figure 1) in this article does not imply endorsement by CDC. The material is in the public domain and available on the CDC website free of charge.

Knowledge, acceptance, and uptake of voluntary counseling and testing for human immunodeficiency virus/acquired immunodeficiency syndrome among undergraduates of a public university in Southwestern Nigeria

Objectives: Human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome (AIDS) is a global public health problem, and Nigeria has about 1.9 million people living with the virus. HIV testing and counseling services serve as a very important entry point to HIV/AIDS care and treatment. Voluntary counseling and testing (VCT) is one of the interventions developed to tackle the HIV/AIDS epidemic in Africa. This study determined the knowledge, acceptance, and utilization of VCT for HIV/AIDS among undergraduates in a public University in Southwestern Nigeria. Material and Methods: The study adopted a descriptive cross-sectional design, using the multistage sampling technique to select 425 respondents. A self-administered questionnaire was used for data collection. Data analysis was done using Statistical package for the social sciences (SPSS), version 25. Descriptive statistics were presented in tables and figures, and inferential statistics were analyzed at a level of significance of 0.05. Results: Over half of the respondents, 226 (53.2%) were within the age range of 18–25 years. The majority were female, 345 (81.2%), single 403 (94.8%), and had never had sexual intercourse 300 (70.6%). Over half of the respondents’ 240 (57%), had above average knowledge of VCT for HIV/AIDs, had above average levels of acceptance 254 (59%), and the majority 326 (76.2%) of the respondents had very low level of utilization of VCT for HIV/AIDS. There was a significant association between respondents’ age (χ2 = 55.599a, P = 0.000), gender (χ2 = 19.094a, P = 0.000), religion (χ2 = 8.990a, P = 0,038), marital status (χ2 = 8.411a, P = 0.038), age at first sex (χ2 = 61.847a, P = 0.000), knowledge of VCT (χ2 = 5.297a, P = 0.021), acceptance of VCT (χ2 = 80.235a, P = 0.000), and their uptake of VCT for HIV/AIDs. Furthermore, selected socio-demographic characteristics, knowledge, and acceptance of VCT significantly predicted the uptake of VCT among respondents (F [8,416] = 20.163, P &lt; 0.05). Conclusion: The study concluded that respondents had an above average knowledge and acceptance of VCT but a low level of utilization. To increase the utilization of VCT for HIV/AIDS among undergraduates, public health programs should focus on educating undergraduates and significant others on the importance of VCT in the context of HIV prevention, care, and treatment.

Effectiveness of human immunodeficiency virus prevention strategies by mapping the geographic dispersion pattern of human immunodeficiency virus prevalence in Nanning, China

BackgroundThe Guangxi government initiated two rounds of the Guangxi AIDS Conquering Project (GACP) in 2010 (Phase I) and 2015 (Phase II) to control human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome (AIDS) epidemics. However, the effectiveness of GACP in HIV prevention and treatment has rarely been reported. This study aimed to assess the effectiveness of the GACP implemented in Guangxi, China and provide data for strategy and praxis improvements to achieve Joint United Nations Programme on HIV/AIDS (UNAIDS) 95-95 targets.MethodsWe used spatial approaches to trace the spatiotemporal distribution properties, epidemic trends, and correlation between macroscopic factors and HIV incidence using data from the Chinese HIV/AIDS case reporting system to explore the effects of the GACP.ResultsDuring the GACP era, the HIV epidemic stabilized in urban centers, showing a downward trend in the Hengzhou and Binyang Counties in the eastern region, whereas it continued to increase in rural areas of the northwest region, such as the Long’an, Mashan, Shanglin, and Wuming Districts. The linear directional mean (LDM) of HIV infection reported cases displayed a southeast–northwest direction, with an LDM value of 12.52°. Compared with that in Phase I, Hengzhou withdrew from the high-high clustering area, and the west–north suburban counties pulled out the low-low clustering area during Phase II. Significant HIV clusters were identified in the eastern region during Phase I, whereas these clusters emerged in the northwestern areas during Phase II. Regarding HIV, socioeconomic status, population mobility, and medical care levels were the key social drivers of heterogeneous spatial distribution.ConclusionsThe GACP assisted in effectively managing the HIV epidemic in urban and eastern areas of Nanning City. However, prevention and control efforts in rural regions, particularly those located in the northwest, may not have yielded comparable outcomes. To address this disparity, allocating additional resources and implementing tailored intervention measures for these rural areas are imperative.

Prevention and infection control of HIV infection and AIDS

Background: Although the global incidence of human immunodeficiency virus (HIV) has decreased significantly since modern antiretroviral therapy (ART), new HIV infections steadily occur, in the Republic of Korea. Based on the understanding of the risk factors for HIV infection, combined strategic behavioral and biomedical interventions should be implemented to reduce HIV infection. This paper reviews the strategies for the prevention of HIV infection.Current Concepts: While the consistent use of latex condoms is effective for the prevention of HIV transmission, consistent use of condoms is low among sexually active individuals. ART can be initiated, after exposure, to prevent HIV infection (post-exposure prophylaxis) after occupational or sexual exposure, injection drug use, and other nonoccupational exposures to HIV. There is a negligible risk of sexual transmission of HIV when the HIV-infected sexual partner has durably suppressed viral replication with ART. Antiretroviral agents have been shown to be highly effective when administered prophylactically to HIV-uninfected but at-risk individuals (preexposure prophylaxis). A high-risk group, such as men who have sex with men, is required to be included in health insurance care benefits for pre-exposure prophylaxis, in addition to the current partners of HIV-infected individuals, to ensure its efficacy.Discussion and Conclusion: HIV-related deaths are rapidly decreasing, but new HIV infections continue to occur. In an environment where a cure or the development of vaccines is unlikely, a multifaceted and proactive approach is required to minimize new HIV infections.

Development of a risk estimation model for condomless sex among college students in Zhuhai, China: a cross-sectional study

BackgroundCondom use at last intercourse is an effective indicator for human immunodeficiency virus (HIV) prevention. To identify at-risk individuals and improve prevention strategies, this study explored factors associated with condomless sex at last intercourse in the last year and developed a risk estimation model to calculate the individual possibility of condomless sex among college students in Zhuhai, China.MethodsA cross-sectional study was conducted among 1430 college students who had sex in the last year from six universities in Zhuhai. The least absolute shrinkage and selection operator (LASSO) and logistic regression were performed to explore the predictors of condomless sex. The nomogram was constructed to calculate the individual possibility of condomless sex. Discrimination and calibration of the nomogram were evaluated using the area under the receiver-operator characteristic curve (AUROC) and the calibration curve.ResultsThe proportion of students who had condomless sex at last intercourse was 18.2% (260/1430). Students who had experienced more types of intimate partner violence (aOR, 1.58; 95% CI, 1.31 ~ 1.92) and had anal sex (aOR, 1.75; 95% CI, 1.06 ~ 2.84) were more likely to have condomless sex. Students who had heterosexual intercourse (aOR, 0.37; 95% CI, 0.21 ~ 0.70), used condoms at first sex (aOR, 0.20; 95% CI, 0.14 ~ 0.27), had high attitudes towards condom use (aOR, 0.87; 95% CI, 0.80 ~ 0.95) and self-efficacy for condom use (aOR, 0.84; 95% CI, 0.78 ~ 0.90) were less likely to have condomless sex. The nomogram had high accuracy with an AUROC of 0.83 and good discrimination.ConclusionsIntimate partner violence, anal sex, condom use at first sex, attitude towards condom use, and self-efficacy for condom use were associated with condomless sex among college students. The nomogram was an effective and convenient tool for calculating the individualized possibility of condomless sex among college students. It could help to identify individuals at risk and help universities and colleges to formulate appropriate individualized interventions and sexual health education programs.

“We mostly focus on preventing pregnancy, we don’t really focus on preventing HIV … ”: Young people’s perceptions and priorities when preventing unplanned pregnancy and HIV

In South Africa, the high rate of human immunodeficiency virus (HIV) infection among young people and unplanned pregnancies remains a concern. Using a qualitative approach, this study aimed to explore how young people between 18 and 24 years old perceive the risk of unplanned pregnancy and HIV, and how they give priority to and act to prevent both concerns. Fifty-four young people were recruited from three provinces in South Africa: KwaZulu-Natal, Eastern Cape, and Gauteng. Data collection took place between May and June in 2016. All data collection was carried out in person using a standardised discussion guide and a semi-structured interview guide in English. We conducted eight focus group discussions with young people and three in-depth interviews with young people who had become parents in their teens. We utilised thematic analysis grounded in a social constructionist framework to assess patterns and associations in the data. Respondents reported unplanned pregnancy and HIV as prevalent among their peers, but prioritised both concerns differently. Preventing pregnancy was a greater priority and threat than HIV. Respondents were less concerned about being infected with HIV which was perceived as invisible and not a death sentence because of the efficacy and ease of use of treatment. HIV was considered comparatively more manageable and less burdensome than other chronic illnesses and unplanned pregnancy. Our study suggests unplanned pregnancy and HIV prevention interventions should prioritise responding to young people’s primary desire to control their fertility, but also encourage them to have holistic sexual and reproductive health goals that include HIV prevention. Our findings suggest a pressing need for biomedical therapies that offer combined HIV and pregnancy prevention for young people. Future programmes need to be agile and innovative in addressing young people’s tendency to prioritise HIV and pregnancy differently, and they need to revive the sense of urgency to prevent HIV.
