How severe is the spread of COVID-19 in your community? If you’re confused, you’re not alone. Though state and local dashboards provide lots of numbers, from case counts to deaths, it’s often unclear how to interpret them — and hard to compare them to other places.
“There hasn’t been a unified, national approach to communicating risk, says Danielle Allen, a professor and director of the Edmond J. Safra Center for Ethics at Harvard University. “That’s made it harder for people,” she says.
Allen, along with researchers at the Harvard Global Health Institute, is leading a collaboration of top scientists at institutions around the country who have joined forces to create a unified set of metrics, including a shared definition of risk levels — and tools for communities to fight the coronavirus.
The collaboration launched these tools Wednesday, including a new, online risk-assessment map that allows people to check the state or the county where they live and see a COVID-19 risk rating of green, yellow, orange or red. The risk levels are based upon the number of new daily cases per 100,000 people.
