According to the National Syndemic Diseases Control Council’s Kenya HIV Estimates Report 2026, Kenya has demonstrated significant progress in reducing mother-to-child HIV transmission rates between 2012 and 2026. The transmission rate began at 14% in 2012, dropped to 8.3% in 2014, but rose to 11.5% in 2016. Following this setback, a steady decline occurred, reaching a record low of 7.3% in 2024. Despite a slight rebound to 9.3% in 2025, the rate settled at 8.04% in 2026. Antiretroviral therapy (ART) remains the essential medical intervention for virus suppression; however, adherence remains a significant challenge. Specifically, healthcare data indicates that 38% of new pediatric HIV infections result from mothers discontinuing ART during breastfeeding. While the long-term trend shows substantial improvement, consistent treatment adherence remains vital to preventing vertical transmission and protecting infants.
