Virus Outbreak Phone Surveillance

This April 28, 2020, photo shows a smartphone app built for the state of Utah displaying coronavirus test sites. The app tracks symptoms and shares location data for contact tracing, the process of determining who might have been exposed to the virus. The app is “a tool to help jog the memory of the person who is positive so we can more readily identify where they’ve been, who they’ve been in contact with, if they choose to allow that,” said Angela Dunn, Utah’s state epidemiologist.
