Kenya’s HIV epidemic carries a deeply gendered burden that national aggregate figures alone cannot fully convey.  

Of the 1,326,416 Kenyans currently living with HIV, the data reveals a persistent and troubling pattern: that women are disproportionately affected at every level in new infections, regional hotspots, and most alarmingly, among the youngest and most vulnerable age groups. 

With 20,106 new infections recorded, women account for 13,233 new infections compared to 6,868 among men, meaning females are contracting HIV at nearly twice the rate of their male counterparts.  

This dashboard, drawing on data from the National Syndemic Diseases Control Council (NSDCC), maps that disparity across Kenya’s 47 counties, illuminating where the gender gap is widest, which age groups face the greatest risk, and what the geographic concentration of cases tells us about the structural forces driving transmission. 

The gender dimension of Kenya’s HIV epidemic is stark and consistent. Of 20,106 new infections, women account for 13,233 compared to 6,868 among men, meaning females are contracting HIV at nearly twice the rate of males.  

The lake region and the capital city carry the heaviest gendered burden of the epidemic 

This disparity is starker among young women aged 15-24 years, where Nairobi alone recorded 697 new female incident cases against just 117 male cases in the same age group, reflecting the heightened biological, social, and economic vulnerabilities that young Kenyan women face.  

Migori followed with 525 female incident cases in this age bracket, and Kisumu recorded 423, reinforcing the western Kenya lake region as a zone of compounded vulnerability for young women. 

Among young males aged 15-24 years, Migori led with 154 incident cases, followed by Kisumu at 126 and Nairobi at 117, figures that, while significant, pale against the female case counts in the same counties. The People Living with HIV (PLHIV) gender gap is most pronounced in Nairobi at 59,786, followed by Migori at 35,090, Homa Bay at 30,775, and Kisumu at 29,496, confirming that the lake region and the capital city carry the heaviest gendered burden of the epidemic.  

Economic dependence and social norms render standard prevention messaging insufficient on its own 

Youth vulnerability indices tell an equally concerning story, with Tharaka-Nithi recording the highest score of 7, followed by Marsabit and Kitui at 6 each counties not typically associated with high HIV prevalence, suggesting that vulnerability among young people is spreading beyond traditional hotspot regions into areas where services and awareness may be even more limited. 

Nairobi’s PLHIV gender gap of 59,786, the highest in the country combined with Tharaka-Nithi’s youth vulnerability index of 7, the highest nationally, signals that both urban inequality and rural neglect are fuelling gender-unequal transmission. The data makes a compelling and urgent case: Kenya’s HIV response cannot be gender-neutral and expect equitable outcomes.  

Young women, particularly those aged 15-24 years in the lake region and Nairobi face a convergence of biological susceptibility, gender-based power imbalances, economic dependence, and social norms that render standard prevention messaging insufficient on its own.  

Closing the gender gap will require targeted interventions, from expanding access to pre-exposure prophylaxis (PrEP) for young women, to addressing the economic drivers of transactional relationships, strengthening gender-based violence response systems, and ensuring that HIV education in schools and communities speaks directly to the realities young Kenyan women navigate daily.  

The numbers are not just statistics; they are a policy directive. Any effective HIV response must centre women and girls as its primary focus.
