A large study in Kenya and Uganda showed that community health workers can dramatically reduce the number of new HIV cases by delivering tests and preventive medicines directly to homes instead of people visiting clinics[1][2]. This approach, supported by digital tools and a smartphone app, reduced new infections by 70 percent[1][2]. The intervention involved 16 remote rural communities, and over two years, seven people out of approximately 42,000 became infected in the intervention groups compared to 22 people in the control groups[2]. The study included nearly 500 community health workers, most of whom had no prior experience with smartphones or HIV service delivery, but most found implementation easy[2]. According to researchers, longer-term medication could potentially reduce the incidence of HIV by up to 99 percent[1]. These findings were presented at the 2026 Conference on Retroviruses and Opportunistic Infections in Denver[1][2].
