It was a real-world example of the sort of public health measures many experts long have been urging: frequent testing — even of people with no symptoms — combined with contact tracing and technology-enabled exposure notifications.

They developed an app that monitors results and can quickly notify close contacts of anyone testing positive. Those who test positive are instructed to quickly self-isolate. Masks are required, and large gatherings were put off-limits. Modeling developed in-house projected it would all work.
