It’s not an easy read, but Harvard scientists have put together a detailed plan for reopening.
"Roadmap to Pandemic Resilience: Massive Scale Testing, Tracing, and Supported Isolation (TTSI) as the Path to Pandemic Resilience for a Free Society," lays out how a massive scale-up of testing, paired with contact tracing and supported isolation, can rebuild trust in our personal safety and re-mobilize the U.S. economy.
Among the report’s top recommendations is the need to deliver at least 5 million tests per day by early June to help ensure a safe social opening. This number will need to increase to 20 million tests per day by mid-summer to fully re-mobilize the economy.
For a video explanation of the Roadmap, see Vi Hart's video "How We Reopen" on YouTube.
