Background

Human immunodeficiency virus (HIV) is a retrovirus that attacks and destroys the immune system’s CD4+ T cells, significantly increasing a person’s vulnerability to other infections and diseases. It is primarily transmitted through contact with infected bodily fluids, including unprotected sexual contact, intravenous drug use, pregnancy, and breastfeeding. Since its recognition as an epidemic in the early 1980s, HIV has been the subject of widespread public concern and numerous misconceptions regarding its symptoms and modes of transmission.
The establishment of HIV latency, a key obstacle to curing the infection, occurs early in the disease process. Latently infected cells, mainly resting memory CD4+ T cells, harbor dormant virus reservoirs that evade immune detection and antiretroviral therapy (ART). These reservoirs are found in multiple anatomical sites such as circulating blood cells, lymphoid tissues, and the brain, complicating efforts to eliminate the virus completely.
Despite ongoing challenges, global efforts to control HIV have seen significant progress. In 2023, an estimated 1.3 million individuals worldwide acquired HIV, representing a 39% decline in new infections since 2010 and a 60% decline since the epidemic peak in 1995. This reduction underscores advances in prevention, treatment, and awareness, although persistent stigma and barriers to ART adherence continue to impact outcomes.
Meanwhile, scientific advances in genetic engineering and gene therapy are beginning to open new avenues for potential cures. Although early gene therapy research encountered setbacks due to genotoxic events, recent technological progress has renewed optimism, exemplified by the approval of gene therapies targeting genetic disorders starting in 2017. These developments hold promise for future HIV treatment strategies aimed at eradicating latent reservoirs and achieving durable remission.

Epidemiology and Global Trends in 2025

The global epidemiology of HIV in 2025 reflects both significant progress and persistent challenges. Despite substantial advances in treatment and prevention, HIV remains a major public health issue with notable regional disparities and evolving demographic patterns.

Global Prevalence and Incidence

As of 2025, approximately 20.8 million people living with HIV (PLHIV) reside in eastern and southern Africa, the region most severely affected by the epidemic. Western and central Africa account for 5.1 million PLHIV, while Asia and the Pacific have 6.7 million, and Western and Central Europe and North America have 2.3 million individuals living with the virus. Although the number of AIDS-related deaths has declined by 69% since its peak in 2004, about 630,000 people died from AIDS-related illnesses worldwide in 2023, underscoring the continuing toll of the disease.
Incidence rates show uneven trends across regions and even within countries. In sub-Saharan Africa, HIV prevalence exhibits substantial local variation, with differing rates of change in incidence and mortality between 2000 and 2017. These variations complicate efforts to monitor and respond effectively to the epidemic, especially given the limited availability of direct empirical data in some high-burden settings.

Age and Demographic Shifts

The demographic profile of people living with HIV is shifting globally. In Asia, analysis of the TAHOD-LITE cohort projects that by 2025 nearly one-third of the HIV-positive population will be aged 50 or older, reflecting improved survival due to antiretroviral therapy (ART) and aging cohorts. The mean age of this population increased from 32 years in 2000 to 41 years in 2013 and is expected to rise to 45 years by 2025.
Adolescent girls and young women remain disproportionately affected in sub-Saharan Africa, accounting for 25% of all new HIV infections globally in 2017 despite representing just 10% of the population. Among adolescents in the region, 80% of infections occur in girls aged 15–19 years. Additionally, key populations such as sex workers, men who have sex with men, transgender individuals, and people who inject drugs continue to experience higher HIV burdens worldwide.

Challenges in the Global Response

Efforts to reach the UNAIDS 95-95-95 targets—95% of people living with HIV knowing their status, 95% of those diagnosed receiving ART, and 95% of those on treatment achieving viral suppression—are ongoing but uneven. An estimated additional 5.6 million PLHIV still need to be diagnosed, treated, and virally suppressed to meet these goals by 2025. Funding constraints and legal barriers remain critical obstacles, particularly in regions with restrictive laws criminalizing LGBTQ+ populations, sex workers, and other key groups.
Human rights restrictions continue to impede effective HIV responses, especially in parts of Africa where harsh anti-gay laws are enforced. Civil society empowerment remains essential for progress, but ongoing stigma and conspiracy beliefs—such as the misconception that a cure is being withheld—pose further challenges to prevention and treatment efforts.

Progress and Outlook

While overall HIV-related mortality has declined globally—with the death rate in the United States halving between 2010 and 2021—incidence rates have not decreased as rapidly, threatening the achievement of 2020 and 2030 global targets. The World Health Assembly’s agenda in 2025 continues to emphasize integrated responses to HIV, hepatitis, and sexually transmitted infections as part of a comprehensive global health strategy.
Continued commitment to equitable treatment access, expanded testing, and addressing social determinants of health is critical. Without sustained efforts, including legal reforms and enhanced funding, the goal of ending the AIDS epidemic by 2030 may remain out of reach.

Advances in HIV Treatment and Management

Over the past several decades, significant progress has been made in the treatment and management of HIV, greatly improving the life expectancy and quality of life for people living with the virus. Modern antiretroviral therapies (ART) have enabled many individuals to suppress HIV to undetectable levels, which not only benefits their health but also prevents transmission to others. However, lifelong adherence to these treatments remains essential and can pose emotional and physical challenges due to side effects and pill burden.

Improvements in Antiretroviral Therapies

Antiretroviral drugs have transformed HIV from a fatal diagnosis into a manageable chronic condition. Despite their effectiveness, many ART regimens come with side effects ranging from bone loss, heart disease, and diabetes to kidney damage, impacting patients’ overall health and quality of life. Daily dosing requirements, except for some newer injectable drugs, can also be burdensome. To address these issues, research is focusing on developing long-acting formulations and innovative treatment options that can reduce dosing frequency and improve adherence.
Lenacapavir, for instance, is a promising long-acting agent under development that may offer oral and injectable options with dosing frequencies tailored to individual needs. Additionally, broadly neutralizing antibodies (bNAbs) have shown potential in maintaining viral control over extended periods in some patients, suggesting new avenues for treatment and prevention.

Emerging Gene Therapy and Cure Research

The pursuit of an HIV cure remains a critical goal in the scientific community. Recent breakthroughs in gene-editing and stem cell transplant therapies have offered hope for potential functional cures. Notably, in February 2022, a woman living with HIV who underwent a stem cell transplant using cord blood and adult stem cells for leukemia treatment showed no evidence of viral rebound after stopping ART for over a year, marking a significant milestone in cure research.
Similarly, the “Geneva patient,” treated with a stem cell transplant in July 2023, was reported as ‘cured’ of HIV. Furthermore, novel gene-editing therapies such as EBT-101 have received fast-track designation from the FDA and are currently in clinical trials aiming to excise HIV DNA from infected cells, potentially eradicating the virus.
Advances in gene therapy technologies, including safer delivery systems and improved targeting methods, have revitalized efforts to develop definitive cures not only for HIV but for various chronic and infectious diseases. Despite earlier setbacks related to genotoxicity, modern techniques have enhanced the safety profile of these approaches.

Managing Drug Resistance and Complex Care

One of the ongoing challenges in HIV treatment is the emergence of drug-resistant viral strains, which can limit the effectiveness of available therapies and complicate management strategies. Understanding the mechanisms of drug resistance is vital for developing new regimens and preventing treatment failure. Continuous surveillance and research are necessary to monitor resistance patterns, particularly with the expanded use of drugs like dolutegravir, where resistance has been observed in a minority of cases.
Additionally, managing HIV in patients with comorbidities such as cancer or those requiring organ transplantation demands multidisciplinary approaches due to the complexity of drug interactions and increased risks of adverse effects. Updated guidelines emphasize coordinated care to optimize ART management in these scenarios.

Impact of the COVID-19 Pandemic on HIV Research

The COVID-19 pandemic has posed significant challenges to HIV research and clinical trials, causing delays and disruptions worldwide. Despite these hurdles, global efforts continue to focus on advancing treatments and preventive strategies, with several upcoming guideline updates and expert panel meetings planned to refine therapeutic recommendations and improve outcomes.

HIV Virology and Pathogenesis: New Insights in 2025

HIV remains a complex retrovirus that primarily targets CD4+ T cells, undermining the immune system and increasing susceptibility to opportunistic infections and other diseases. Recent advances in 2025 have deepened our understanding of the virological and immunological mechanisms underlying HIV persistence and pathogenesis, challenging many previous assumptions about the virus.
A critical feature of HIV infection is the integration of the viral genome into the host’s chromosomes, particularly within memory CD4+ T cells. This integration is pivotal to viral persistence, as the proviral DNA can remain latent and evade immune detection and antiretroviral therapy (ART), forming a reservoir that is the main obstacle to curing HIV. Latently infected cells are predominantly resting memory CD4+ T cells, which provide a stable reservoir for HIV and allow the virus to rebound rapidly once ART is stopped.
New insights reveal that circulating CD4+ T cells are not the exclusive or even the most favorable environment for establishing HIV latency. Instead, the anatomical location and timing of the emergence of persistently infected cells indicate a more complex interplay between viral replication and host immune environment. Additionally, viral gene expression is influenced by the co-opting of host transcription factors such as AP-1, NFAT-1, Sp1, and IRF-1, which are involved in pro-inflammatory and immune activation signals. This hijacking not only drives viral replication during T cell activation but may also enable HIV to evade host antiviral responses through modulation of innate immunity.
Structural biology breakthroughs, including cryo-electron microscopy studies of the HIV-1 envelope glycoprotein (Env), have elucidated how receptor binding alters viral fusion mechanisms and antibody accessibility. These findings inform the design of broadly neutralizing antibodies (bNAbs) targeting the CD4 binding site of Env, which show promise in reducing viral load in preclinical models. Furthermore, the discovery of unconventional mutations in bNAbs has provided new perspectives on how HIV evades immune recognition, emphasizing the dynamic arms race between virus and host immunity.
Host immune responses play dual roles in HIV infection. While innate immune factors such as cytokines, chemokines, and antiviral restriction factors are activated early during infection, HIV employs multiple strategies to evade these defenses, including interference with interferon-stimulated genes (ISGs) like BST-2 that restrict viral egress. The virus’s ability to manipulate host immune pathways underscores its persistence and pathogenicity.
Efforts to eradicate the latent reservoir through latency reversal agents (LRAs) have thus far been unsuccessful, as reactivation of latent virus often leads to rapid viral rebound once ART is discontinued. However, individuals with higher levels of autologous neutralizing antibodies (aNAbs) exhibit a significant delay in viral rebound, suggesting that immune-mediated control may be enhanced by such antibodies. This phenomenon, known as the “vaccinal effect,” may boost T cell responses and holds potential for future therapeutic strategies.

Prevention Strategies and Public Health Interventions

Efforts to prevent HIV transmission have evolved significantly, driven by advances in biomedical interventions, public health strategies, and global policy initiatives. Central to these efforts is the World Health Organization (WHO) Department of Global HIV, Hepatitis and Sexually Transmitted Infections Programmes, which leads the development and implementation of the global health sector strategy aimed at eliminating HIV as a public health threat.
One of the most impactful biomedical prevention tools is pre-exposure prophylaxis (PrEP). Recent data suggest that improvements in PrEP prescriptions have contributed to a decline in new HIV infections, particularly in regions prioritized by initiatives such as the Ending the HIV Epidemic (EHE) in the United States, where HIV incidence among people aged 13 and older decreased by 21% between 2017 and 2022. Promising research indicates that long-acting injectable PrEP could provide protection for up to a year after a single dose, representing a potential breakthrough in ease of use and adherence. Additionally, the discovery of unusual antibodies capable of controlling HIV without antiretroviral drugs offers hope for future preventive therapies and potential cures.
Antiretroviral therapy (ART) remains a cornerstone of both treatment and prevention. Since the demonstration in 1996 that combination drug regimens can suppress HIV replication and prevent progression to AIDS, ART has dramatically improved the prognosis for people living with HIV. Suppressed viral loads not only improve individual health but also effectively eliminate the risk of sexual transmission, a concept popularly summarized as “undetectable = untransmittable” (U=U). This approach, often referred to as “treatment as prevention,” was recognized as a breakthrough by the scientific community and underpins many public health policies.
Despite these biomedical advances, stigma continues to be a significant barrier to prevention and care. HIV-related stigma negatively affects mental health, reduces health-related quality of life, and undermines adherence to ART, particularly among pediatric and young adult populations. Surveys reveal widespread misconceptions about HIV transmission and treatment;

Common Misconceptions and Stigma in 2025

Despite significant advances in HIV treatment and prevention, misconceptions and stigma surrounding HIV remain pervasive in 2025. A substantial proportion of the general public continues to hold inaccurate beliefs about HIV transmission and the realities of living with the virus. For instance, an online survey conducted by The Harris Poll across Australia, Portugal, the UK, and the USA found that 76% of adults were unaware that effective HIV treatment can suppress the virus to undetectable levels, thereby preventing sexual transmission—commonly known as the “undetectable = untransmittable” or U=U concept. Furthermore, nearly a third of respondents incorrectly believed that HIV could be transmitted through kissing, underscoring persistent misinformation.
Stigma associated with HIV affects many aspects of life for people living with the virus, including mental health, relationships, and community integration. Individuals often fear rejection from families and communities, which can lead to social isolation and changes in daily routines. This stigma is linked with increased symptoms of depression, anxiety, and hopelessness among HIV-positive individuals, as well as poorer adherence to antiretroviral therapy (ART). Although HIV treatment has transformed the prognosis for many, 88% of survey respondents still believed that negative perceptions toward people living with HIV persist widely, indicating that stigma remains a significant barrier to full social acceptance and engagement in care.
Moreover, conspiracy theories and denialist beliefs continue to contribute to stigma and hinder prevention efforts. Studies have documented widespread mistrust in medical institutions among various populations, with some individuals believing that a cure for HIV is being intentionally withheld or that HIV was created as a means of population control. Such beliefs are associated with lower rates of condom use and reduced adherence to ART, thereby increasing the risk of transmission and worsening health outcomes. HIV denialism, though largely discredited within the scientific community, still influences public perceptions and can fuel misinformation campaigns that undermine prevention and treatment efforts.
Economic and social interventions have been proposed to reduce HIV-related stigma, but the mechanisms through which stigma affects treatment adherence and health behaviors remain inadequately understood. Despite the global push toward universal testing and treatment—aiming for 95% of diagnosed individuals to be on treatment and virally suppressed by 2025—stigma continues to pose a major obstacle to these goals. Anti-stigma campaigns and increased education about HIV transmission and treatment efficacy, including the promotion of U=U and pre-exposure prophylaxis (PrEP), are critical for improving knowledge, reducing fear, and fostering supportive environments for people living with HIV.

Societal and Economic Impact

HIV continues to exert a profound societal and economic burden worldwide, disproportionately affecting certain regions and populations. In 2023, eastern and southern Africa bore the highest prevalence with 20.8 million people living with HIV, followed by western and central Africa with 5.1 million, Asia and the Pacific with 6.7 million, and Western and Central Europe and North America with 2.3 million people affected. This uneven distribution exacerbates existing inequalities and places significant strain on healthcare systems and economies in the most impacted areas.
Stigma surrounding HIV remains a critical barrier, impacting mental health, social relationships, and access to healthcare services such as prevention and treatment. Studies reveal that 38% of people living with HIV report diagnoses of anxiety and/or depression, with particularly negative trends noted in Europe and North America. Stigma also undermines career opportunities and intimate relationships, perpetuating cycles of discrimination and marginalization. Community-based initiatives, like Positive Action programmes, aim to mitigate these effects by addressing mental health challenges related to HIV stigma.
Economically, the HIV response faces considerable challenges. Funding for HIV interventions dropped by 5% from 2022 to 2023 and by 7.9% between 2020 and 2023, falling significantly short of the estimated US$ 29.3 billion required in 2025 for low- and middle-income countries to meet global targets. This financial shortfall threatens progress towards ending AIDS as a public health threat by 2030 and risks reversing gains made in reducing HIV-related mortality and incidence. The looming three-year replenishment of the global HIV fund in 2025 occurs amid a challenging political and economic climate, underscoring the need for increased commitment from governments and private sectors.
The historical context illustrates the consequences of inadequate access to treatment: between 1997 and 2006, approximately 12 million people in Africa died waiting for affordable first-generation HIV therapies. Innovations such as long-acting HIV medications offer hope for more accessible and effective treatment options, which could transform prevention and care worldwide.
Global leadership has reaffirmed commitments to combat HIV, adopting political declarations with targets for 2025 to address inequalities impeding the response. Despite these commitments, the current funding landscape remains insufficient, with donor governments providing only $7.9 billion of the $22.1 billion available in 2023 for low- and middle-income countries. The economic and social consequences of HIV continue to reverberate, affecting not only individuals but also the broader health infrastructure and societal stability, particularly in high-burden regions.
The reductions in funding and the resulting uncertainty have sparked concern among researchers, healthcare workers, and advocates, highlighting the urgent need to sustain and expand investment in HIV-related public health and biomedical research to avoid setbacks in global progress.

Challenges and Controversies

The ongoing fight against HIV/AIDS in 2025 is marked by a complex landscape of scientific, social, and economic challenges. Despite significant advances in antiretroviral therapy (ART) and increased access to treatment worldwide, numerous obstacles continue to impede progress toward an ultimate cure and equitable care.
One major challenge is the impact of funding cuts on public health and biomedical research. The recent reductions in U.S. funding for HIV/AIDS research have sparked shock, grief, and anger among thousands of researchers, healthcare workers, and advocates, highlighting concerns about the sustainability of efforts to combat the epidemic. These financial constraints risk slowing the development of newer antiretroviral drugs and innovations critical for managing the disease.
Scientific hurdles also persist. Although ART has transformed HIV from a fatal disease into a manageable chronic condition, the therapies themselves often bring serious side effects, including bone loss, heart disease, diabetes, and kidney damage, which compromise patients’ quality of life and lifespan. Furthermore, while research into gene and cell therapies offers hope for a functional cure by 2025, the path remains uncertain and challenging, particularly as the COVID-19 pandemic has disrupted clinical trials and delayed progress in HIV cure research.
Social stigma and discrimination continue to exacerbate these difficulties. HIV-related stigma remains deeply entrenched, obstructing access to testing, treatment adherence, and broader care initiatives. While economic strengthening and livelihood interventions have been proposed as means to reduce stigma, formal testing of these hypotheses is lacking, and interventions targeting antiretroviral adherence have yielded inconsistent results. The persistence of stigma not only undermines individual health outcomes but also limits the transformative potential of medical advances in controlling the epidemic.
Another source of controversy involves the development and dissemination of clinical guidelines. The federally approved clinical practice guidelines for HIV/AIDS are formulated by expert panels and are regularly updated to reflect emerging evidence and comply with new executive orders. However, the rapidly evolving nature of HIV treatment regimens and the global diversity of healthcare systems pose ongoing challenges in ensuring that guidelines remain relevant, accessible, and effectively implemented.
Finally, despite progress such as a 33% reduction in AIDS-related deaths between 2010 and 2018 and a decline in HIV incidence in many regions, the global burden of HIV remains substantial. With approximately 38 million people living with HIV and 1.7 million new infections in 2018 alone, the epidemic demands sustained and coordinated global responses to close persistent gaps, break down barriers, and address injustices that continue to fuel transmission and hinder treatment.
In sum, the challenges and controversies surrounding HIV/AIDS in 2025 reflect a multifaceted struggle involving scientific innovation, funding priorities, social dynamics, and policy implementation. While advancements in treatment have improved lives, overcoming the enduring obstacles requires renewed commitment and collaboration across sectors to ensure equitable progress toward ending the epidemic.

Future Directions and Research Frontiers

The pursuit of an HIV cure remains a central focus of global health research, building on over four decades of advances in understanding and managing the virus. Recent breakthroughs have signaled promising new avenues, particularly in the field of stem cell and gene therapies. Notably, in February 2022, a woman living with HIV who received a unique stem cell transplant combining cord blood and adult stem cells from a relative showed no viral rebound after 14 months without antiretroviral therapy (ART), representing a potential paradigm shift in HIV cure strategies. Similarly, the “Geneva patient,” a man cured of HIV following a stem cell transplant for cancer treatment in July 2023, exemplifies the clinical potential of such interventions.
Gene therapy is increasingly viewed as a frontier in HIV research, with early setbacks due to genotoxicity now being addressed through advances in genetic engineering. The ex vivo approach, wherein cells are modified outside the body before reintroduction, dominates current HIV gene therapy trials. Since the approval of the first gene therapy targeting genetic mutations in 2017, researchers have renewed efforts to develop safe and effective gene-based cures for HIV. Biopharmaceutical companies like AGT are leading initiatives aimed at moving beyond lifelong ART to functional cures by 2025, leveraging improved understanding of gene and cell therapies.
Despite these scientific advances, challenges remain. Antiretroviral drugs, while life-extending and crucial for viral suppression, carry long-term health risks including bone loss, cardiovascular disease, diabetes, and kidney damage. Moreover, HIV-related stigma continues to undermine ART adherence, which is critical for both individual health outcomes and public health efforts to control transmission. The mechanisms by which stigma affects adherence are not fully elucidated, posing obstacles to the widespread success of “test-and-treat” strategies.
The COVID-19 pandemic has also temporarily disrupted HIV research and clinical trials, although the global commitment to ending AIDS by 2030 remains strong. International organizations such as WHO and UNAIDS continue to lead coordinated efforts, backed by substantial funding from donor governments and multilaterals, to advance both prevention and cure research. Over the next five years, the integration of innovative gene and cell therapies with improved public health approaches promises to reshape the HIV treatment landscape fundamentally.
