US State Rollout of COVID-19 Exposure Notification Apps Remains Fragmented
A new review explores the development and fragmented state-level deployment of Google and Apple's Exposure Notification system during the COVID-19 pandemic. The technology offers privacy-preserving contact tracing, but faces significant adoption hurdles across the United States.
Public health authorities turn to digital technologies like exposure notification to help control the rapid spread of COVID-19. This mobile device-based technology alerts individuals to potential infections without collecting personally identifiable information, making it highly favored for its scalability, ease of use, and strong privacy protections.
A partnership between Google and Apple leads to the creation of the most widely implemented exposure notification protocol in the world, known as GAEN. The development process involves valuable collaboration and discourse between software developers and public health officials to ensure the system meets practical health needs.
Despite its technical promise, the actual rollout of GAEN applications across US states is much more fragmented than originally anticipated. The review highlights how this uneven deployment and limited population-level adoption create ongoing challenges for using the technology as an effective widespread public health tool.
