Engadget: National COVID-19 exposure server could alert people across states

Engadget: National COVID-19 exposure server could alert people across states. “COVID-19 contact tracing apps will only be effective across borders if states and countries can readily share data, and a collaboration could soon make that happen in the US. iMore reports that Apple, Google, and Microsoft are working with the Association of Public Health Laboratories to launch a national server to store keys and help exposure notifications reach people across states. It would be based around Apple and Google’s exposure alert framework, while Microsoft and APHL would host the server.”
