HIV No Longer a Disease of Youth: Prevalence Surges Among Older Adults in Africa
A growing and often overlooked crisis is unfolding in sub-Saharan Africa: HIV prevalence among individuals aged 50 and older is not only increasing but now exceeds that of younger adults, demanding a critical re-evaluation of prevention and treatment strategies.
The number of adults aged 50 years and older living with HIV in sub-Saharan Africa doubled between 2000 and 2016, a trend that continues to accelerate. Projections indicate that by 2040, a full quarter of all people living with HIV in africa will be in this age group, necessitating urgent and tailored interventions.
Did You Know?
The rate of new HIV infections among older adults is rising faster than in almost any other age group. This is partly due to increased life expectancy and better HIV treatment, meaning people with HIV are living longer.
A recent study published in The Lancet Healthy longevity investigated HIV in older populations in Kenya and South Africa, revealing a meaningful gap in understanding and addressing the unique needs of this demographic.According to a researcher involved in the study,perceptions surrounding HIV remain dangerously limited. “We often think of HIV as a disease of younger people. It doesn’t help that intervention campaigns are mainly targeted at the youth.”
This misconception is pervasive, with older adults frequently enough believing they are not at risk. This belief poses a substantial threat to achieving the UNAIDS 95-95-95 targets by 2030 – a global initiative aiming for 95% of people living with HIV to know thier status, 95% of those diagnosed to be on treatment, and 95% of those on treatment to achieve viral suppression.
Understanding the 95-95-95 Targets
These ambitious goals aim to control the HIV epidemic by ensuring that the vast majority of people with HIV are aware of their status,receive treatment,and achieve viral suppression,preventing further transmission.
current HIV surveys overwhelmingly focus on younger individuals, leaving a critical void in data regarding prevalence, incidence, and treatment outcomes in older populations. “While HIV prevalence among individuals over 50 years of age is similar to or even exceeds that of younger adults, HIV surveys focus on younger individuals,” explained an associate professor at the MRC/Wits-Agincourt Research Unit. “This leaves considerable gaps in understanding.”
Stigma Remains a Significant Barrier
Personal Story
“I never thought I could get HIV at my age. It was a shock,and the shame was almost unbearable. It took me a long time to seek help.” – Anonymous, 62 years old.
The uptake of HIV testing among older adults remains alarmingly low, leading to delayed diagnoses and limited access to vital care. this hesitancy is deeply rooted in the pervasive stigma surrounding the disease. A researcher noted, “We certainly know that there is significant social stigma related to HIV infection.This is why understanding HIV-related stigma in older adults remains crucial as a way to inform interventions to support older people’s mental health and overall well-being.”
Effective interventions must prioritize repeated testing opportunities, the utilization of pre-exposure prophylaxis (PrEP), and targeted awareness campaigns designed to reach the elderly. Importantly, HIV can be effectively managed alongside other chronic conditions, as the disease is now understood as a long-term illness requiring ongoing care.
The rise in non-communicable diseases – such as hypertension, diabetes, and obesity – is also impacting older adults in sub-Saharan Africa. Integrating HIV treatment and prevention into existing healthcare systems focused on managing these chronic illnesses offers a pragmatic and efficient approach.
Pragmatic Integration
Integrating HIV care into existing chronic disease management programs can reduce stigma, improve access to care, and streamline healthcare delivery for older adults.
A Complex Web of Risk Factors
The study highlights that a complex interplay of factors influences HIV risk, including age, education level, gender, and geographic location. While access to HIV treatment has improved, older adults – especially those in rural areas – continue to face significant challenges, exacerbated by low education levels and gender inequality.
Data revealed a particularly high HIV rate among widowed women (30.8%),possibly linked to loss of a partner to HIV,the stigma associated with the disease,and increased vulnerability to unsafe sexual practices,including transactional sex,coupled with limited agency in negotiating condom use. Individuals without formal education and those with lower incomes also demonstrated higher rates of infection.
The Power of Longitudinal Data
The study’s strength lies in its longitudinal design, providing valuable insights into the evolving HIV epidemic among older adults in sub-Saharan Africa. “Our study is beneficial in that older populations are under-represented, and not much is known about them over time. What changes are occurring? We have to answer these kinds of questions,” stated a researcher. “With longitudinal data, we can look at the effectiveness of antiretroviral therapy coverage in older people.”
The research utilized data collected in urban Kenya and both urban and rural sites across South Africa between 2013-2016 and 2019-2022. This decade-long examination is yielding crucial insights and addressing critical knowledge gaps regarding HIV in aging populations. The data source was the Africa wits-INDEPTH Partnership for Genomic Research (AWI-Gen), a multi-center longitudinal cohort study spanning six research centers across four sub-Saharan African countries – South Africa, Kenya, Burkina Faso, and Ghana – dedicated to investigating various health determinants.
Addressing this growing crisis requires a fundamental shift in perspective, recognizing that HIV is no longer solely a disease of the young and prioritizing the unique needs of older adults in Africa.

Beyond Stigma: Tailoring HIV Prevention and Care for Older Adults
The previous discussion highlighted the alarming rise in HIV prevalence among older adults in sub-Saharan Africa, emphasizing the need for specific interventions. To effectively address this issue, it’s crucial to move beyond broad strategies and implement tailored approaches that consider the unique circumstances and realities of this demographic. This involves understanding the specific risk factors within this age group, addressing the long-standing stigma, and ensuring accessible and age-appropriate care. This is essential to better protect older adults from HIV, improve their health outcomes, and help them lead long, fulfilling lives. Addressing this crisis demands a shift in perspective and the specific focus on tailored interventions targeted at people 50 years and older.
One of the primary challenges is the lack of specific data related to HIV in older adults. Most HIV surveys and prevention campaigns are geared towards younger populations, leading to importent data gaps regarding prevalence, incidence, and treatment outcomes in the over-50 age group [[3]]. This lack of data hinders the development of effective, evidence-based interventions. Furthermore,the effectiveness of antiretroviral therapy (ART) and pre-exposure prophylaxis (PrEP) in older populations needs further inquiry. This is also vitally important as the disease can then managed along side other health conditions.
Targeted Prevention Strategies: A Multifaceted Approach
Effective prevention strategies must be designed with the specific needs of older adults in mind. This requires focusing beyond traditional approaches and considering the complex interplay of factors influencing their risk.
