HIV remains a leading public-health challenge in Kenya, and young people (roughly ages 15–24) are taking up an increasing share of new infections. This article summarizes the latest national and international data, outlines the main drivers behind the rise among youth, and lists policy- and program-level actions that evidence suggests would help reverse the trend.
What the numbers say (most recent estimates)
- Kenya’s HIV estimates portal reports about 1,326,419 people living with HIV in the country (latest national estimates).
- A large share of new adult infections in Kenya are occurring in adolescents and young people: about 38% of all new adult HIV infections are among those aged 15–24.
- National modelling and recent analyses estimate the number of young adults (15–24 years) living with HIV in Kenya at roughly 160–165 thousand people (modelled estimates in recent Kenya HIV reports).
- The shift in burden is part of a wider regional and global pattern: in 2024 an estimated 370,000 young people aged 15–24 were newly infected with HIV worldwide, with sub-Saharan Africa carrying the largest share.
- Globally, UNAIDS continues to highlight that adolescent girls and young women are disproportionately affected — a fact that is reflected in Kenya’s data and in program priorities.
(Those five sources above are the main factual anchors used in the analysis below.)
Why infections among youths are rising — the main drivers
1. Unequal vulnerability — especially for adolescent girls and young women
Adolescent girls and young women face biological, socio-economic and cultural risks that increase their chance of HIV infection (age-disparate sex, transactional sex, lower negotiating power for condom use). National surveys and UNAIDS analyses show girls in this age group account for a disproportionate share of new infections.
2. Gaps in access to sexual and reproductive health (SRH) services
Many young people — particularly unmarried adolescents — still face barriers to confidential, youth-friendly HIV testing, PrEP (pre-exposure prophylaxis), condoms and sexual health education. Where services are not youth-friendly or are stigmatizing, uptake falls and prevention gaps remain. Kenya’s prevention frameworks and programme reviews point to these service gaps as critical bottlenecks.
3. Social and economic drivers (poverty, schooling, migration)
Poverty and limited schooling raise the likelihood of transactional sex or early sexual debut. Urban migration and informal work can expose youth to networks with higher HIV prevalence. These structural drivers are repeatedly identified in Kenya’s HIV situation analyses.
4. Gender-based violence (GBV) and coercion
GBV increases both the biological and behavioural risk of HIV acquisition. Young women who have experienced violence are less able to negotiate condom use and more likely to have older sexual partners — a pattern linked to higher HIV risk in national studies.
5. Service disruptions and funding pressures
Interruptions to prevention and testing services — whether caused by health system shocks (e.g., COVID-19 era disruptions) or reductions in donor support — reduce routine testing, community outreach and PrEP delivery. Recent national reporting and international commentary have flagged concerns about funding and program continuity as threats to progress.
6. Low use of combination prevention among youth
While biomedical tools exist (condoms, voluntary medical male circumcision, PrEP, treatment as prevention), uptake among adolescents and young adults is uneven. Low risk perception, stigma about accessing services, and limited targeted outreach mean many young people do not use the full mix of prevention options.
7. Information gaps, misinformation and social norms
Digital misinformation, limited comprehensive sexuality education in some settings, and cultural taboos about discussing sex with adolescents can leave young people uninformed about how to protect themselves. Programs that combine accurate SRH education with service linkages have been shown to improve prevention behavior.
What works — evidence-based actions to turn the tide
Program and policy responses that programs and international agencies recommend for Kenya include:
- Scale up youth-friendly testing and prevention (bring HIV testing, PrEP and condoms to schools, youth centers and community outlets; make services confidential and non-judgmental).
- Prioritise adolescent girls and young women with combination packages — economic empowerment, GBV prevention, SRH services and PrEP where indicated.
- Strengthen social-behavioural interventions — comprehensive sexuality education adapted for local contexts, digital outreach, and peer-led mobilisation.
- Protect and stabilise funding for prevention so community outreach, testing and PrEP programs are continuous and can reach remote and high-risk youth populations.
- Improve data and local targeting — use county-level estimates and hotspot mapping to target interventions where new infections among youth are rising fastest.
Kenya has made strong gains in HIV control overall, but recent national and global data show young people — especially adolescent girls and young women — are shouldering a growing share of new infections. The rise among youth is driven by a mix of biological vulnerability, social and economic inequality, service gaps, and program/funding pressures. Reversing the trend requires scaling youth-friendly, combination prevention and stabilising the delivery platforms that reach adolescents where they live, learn and work.
