Why Are HIV Diagnoses Among Men Who Have Sex with Men Still Rising?

Recent worldwide data on HIV offer reasons for cautious optimism. UNAIDS reports that more than 21 million individuals are now receiving antiretroviral therapy, the gold-standard treatment for HIV infection. In addition, annual AIDS-related deaths have declined to under one million — the lowest level recorded since the beginning of the 21st century.

At the same time, global health organizations have emphasized measurable public health targets. Many nations committed to the “90-90-90” benchmarks by 2020: 90 percent of people living with HIV knowing their status, 90 percent of those diagnosed receiving treatment, and 90 percent of people on treatment achieving an undetectable viral load. These goals were designed to reduce HIV transmission rates and improve long-term outcomes through consistent access to antiretroviral therapy.

Yet despite this progress, new HIV diagnoses continue to increase in specific populations — particularly among men who have sex with men (MSM). Globally, MSM face a risk of acquiring HIV that is approximately 27 times higher than that of other groups. Understanding why this disparity persists is essential for developing effective prevention strategies and equitable healthcare policies.

When examining health communication trends — much like people explore topics such as Put some pep in your step origin or search for Put some pep in your step origin urban dictionary to better understand cultural context — it becomes clear that awareness and access to accurate information are powerful tools. In HIV prevention, informed communities and accessible services can significantly influence testing rates, early diagnosis, and adherence to treatment.

Regional statistics

Although MSM are disproportionately affected by HIV worldwide, the percentage of new diagnoses differs by geographic area. According to data compiled by UNAIDS for 2017, MSM accounted for approximately:

• 57 percent of all new cases in North America, central Europe, and western Europe
• 41 percent of all new cases in Latin America
• 25 percent of all new cases in Asia, the Pacific, and the Caribbean
• 20 percent of all new cases in eastern Europe, central Asia, the Middle East, and North Africa
• 12 percent of all new cases in western and central Africa

While these figures vary by region, the overarching pattern remains consistent: in most parts of the world, MSM experience a significantly higher likelihood of HIV diagnosis compared to other populations. These disparities highlight the need for region-specific prevention initiatives combined with broader structural reforms.

Regional and universal challenges

Each region faces distinct barriers in preventing new HIV infections. In several countries — particularly in parts of Africa and the Middle East — sexual relationships between men are criminalized. Such laws can drive MSM underground, discouraging them from seeking medical counseling, HIV testing, or treatment for sexually transmitted diseases. Criminalization also limits the ability of healthcare professionals and advocacy organizations to provide accurate sexual health education and HIV prevention resources.

Even in countries where same-sex relationships and marriage are legally recognized, stigma, discrimination, and homophobia remain pervasive. These social pressures can deter MSM from accessing preventive healthcare services or disclosing risk factors to providers. The fear of judgment — especially in clinical settings — may reduce the likelihood of routine HIV screening and open conversations about sexual health.

Access to HIV testing differs widely across countries. When individuals avoid testing, they may remain unaware of their HIV status and therefore miss the opportunity to begin antiretroviral therapy early. Early diagnosis is critical not only for preserving immune function but also for lowering the risk of onward transmission. Without treatment, viral load remains detectable, increasing the potential for spread.

According to the Centers for Disease Control and Prevention (CDC), roughly 1 in 6 MSM in the United States who are living with HIV do not know they have the virus. In certain countries, the numbers are even more concerning. In Kenya, Malawi, and South Africa, an estimated one in three MSM with HIV are unaware of their infection. These gaps in awareness represent missed opportunities for timely intervention.

Biological factors also contribute to increased vulnerability. Most MSM acquire HIV through anal sex without a condom. Condom-less anal sex carries a higher probability of HIV transmission compared to some other sexual activities, including oral sex. Consistent and correct condom use remains a cornerstone of HIV prevention.

However, condom usage rates among MSM vary considerably worldwide. Limited access to condoms, insufficient sex education, and cultural attitudes toward condom use can all influence behavior. In regions where condom availability is restricted or social stigma is strong, MSM face higher risks not only of HIV but also of other sexually transmitted diseases such as syphilis, gonorrhea, and chlamydia.

Biomedical prevention tools have significantly advanced in recent years. Pre-exposure prophylaxis (PrEP) and post-exposure prophylaxis (PEP) are antiretroviral medications that dramatically lower the risk of HIV transmission. When taken as prescribed, PrEP can prevent infection even after potential exposure, and PEP can reduce risk if started promptly after exposure. Despite their proven effectiveness, global access to PrEP and PEP remains uneven. In many settings, individuals at highest risk encounter obstacles including cost, limited supply, or lack of awareness about these preventive options.

Actionable solutions

Although these challenges are substantial, evidence-based interventions demonstrate that meaningful progress is achievable. Expanding access to antiretroviral therapies — especially PrEP — on a large scale has shown measurable benefits. Countries such as Australia, Brazil, Kenya, South Africa, United States, and Zimbabwe have implemented broad PrEP initiatives targeting high-risk populations.

Early results are encouraging. In one Australian region, the swift rollout of PrEP corresponded with a 35 percent reduction in new HIV diagnoses. Public education campaigns and community outreach played a critical role in informing individuals about eligibility, safety, and effectiveness.

Community-centered healthcare delivery is another promising approach. Programs that employ trained community health workers can foster trust, improve engagement, and support adherence to antiretroviral therapy. When people feel understood and respected, they are more likely to maintain regular medical appointments and follow prescribed treatment plans, which in turn helps achieve and sustain an undetectable viral load.

Digital innovation also offers new avenues for outreach and prevention. In China, the dating application Blued integrated a feature connecting its 40 million users to nearby HIV testing centers. This convenient appointment-booking system led to a 78 percent increase in HIV testing at clinics promoted through the app in 2016. Leveraging technology in this way can reduce logistical barriers and normalize routine testing.

Policy reform is equally important. Decriminalizing same-sex relationships and actively combating discrimination can substantially improve public health outcomes. UNAIDS emphasizes that inclusive policies encourage individuals living with HIV to seek medical care and remain engaged in treatment programs. Legal protections and anti-discrimination measures can foster safer healthcare environments.

Additionally, ensuring affordable healthcare and eliminating user fees for essential services can remove financial barriers to HIV testing and antiretroviral therapy. When cost is no longer prohibitive, more individuals are able to access preventive medications like PrEP, initiate timely treatment, and maintain long-term care — all of which contribute to lower transmission rates.

The takeaway: Looking at the big picture

Although global HIV infections among MSM remain a pressing concern, the vision of achieving 90-90-90 targets continues to guide international efforts. Progress requires coordinated action between community organizations, healthcare providers, policymakers, and governments. Expanding access to HIV testing, antiretroviral therapy, PrEP, and PEP is fundamental to protecting those at greatest risk.

Leaders in public health, business, and government must collaborate to secure sustainable funding and enact policies that prioritize equity in healthcare access. Ending the HIV epidemic among MSM — and ultimately across all populations — demands both local engagement and global solidarity. With evidence-based prevention strategies, inclusive laws, and accessible treatment, meaningful and lasting reductions in HIV transmission are within reach.
