A large implementation study funded by the National Institutes of Health demonstrated a 70% reduction in new HIV infections in rural communities in Kenya and Uganda by integrating digital tools with tailored HIV services delivered by community health workers and clinicians. The findings were presented at the Conference on Retroviruses and Opportunistic Infections 2026.
Real-World Strategy to Address Gaps in HIV Care
Despite the availability of effective prevention and treatment options, HIV incidence remains substantial, with approximately 1.3 million new infections globally each year. A key barrier is the inability of health systems to consistently reach and retain individuals in prevention and care programs.
To address this, researchers from the Sustainable East Africa Research in Community Health (SEARCH) consortium evaluated a scalable, population-level intervention using existing healthcare infrastructure and locally available tools.
Jeffrey K. Taubenberger, M.D., Ph.D., acting director of the National Institute of Allergy and Infectious Diseases, emphasized that the study highlights the importance of testing HIV strategies in real-world settings, where implementation challenges often limit impact.
Study Design and Intervention Approach
The trial included 16 rural communities eight in Kenya and eight in Uganda. Communities were paired based on similar characteristics and then randomized to receive either the intervention or standard HIV care.
The intervention, delivered over two years starting in 2023, included three key components:
- Community-based HIV testing: Government-employed health workers conducted home visits to offer testing. Individuals who tested positive were referred for treatment, while those at risk were linked to prevention services.
- Personalized clinical care: Healthcare providers were trained to deliver HIV prevention and treatment tailored to individual needs and preferences.
- Digital integration: A ministry-compatible mobile application connected community workers with clinicians, medical records, and health services, enabling better follow-up and delivery of prevention medications.
Significant Reduction in HIV Incidence
After two years, HIV incidence was measured across approximately 84,000 participants. Only seven new infections were recorded among about 42,000 individuals in intervention communities, compared with 22 cases in control communities. This corresponds to a 70% reduction in new HIV infections.
The reduction was consistent across age groups, sexes, and both countries.
Increased Uptake of Preventive Therapies
The study also found a marked increase in the use of biomedical prevention methods. Among individuals without HIV, 1.67% in intervention communities reported recent use of pre-exposure prophylaxis or post-exposure prophylaxis, compared with 0.41% in control communities. This reflects a four-fold increase in prevention uptake.
At the same time, both intervention and control groups maintained high levels of HIV treatment coverage and viral suppression, indicating that improved prevention uptake alongside effective treatment contributed to the observed reduction in new infections.
Feasibility and Implementation
Most community health workers and clinicians reported that the intervention was easy to implement, despite limited prior experience with smartphones or HIV service delivery among many workers. Participants also responded positively to the approach.
Implications
The findings demonstrate that combining community-based outreach, personalized care, and digital tools within existing health systems can significantly reduce HIV incidence. This implementation model may be adaptable to other regions, including high-income settings, to improve HIV prevention and care delivery.
