Interactive map from Harvard uses new coronavirus cases in last seven days to estimate risk level by county

How much is your county at risk from the coronavirus? A new mapping tool from Harvard University estimates that, based on the number of new cases per 100,000 people in the previous seven days.

“The public needs clear and consistent information about covid risk levels in different jurisdictions for personal decision-making, and policymakers need clear and consistent visibility that permits differentiating policy across jurisdictions,” Danielle Allen, director of Harvard's Edmond J. Safra Center for Ethics, said in a news release.

The map is color-coded but interactive, allowing users to see the data behind the colors, which are:
  • Green: Less than one case a day per 100,000 people, and containment is on track. Use contact tracing and testing to monitor.
  • Yellow: One to nine cases a day per 100,000 people, indicating community spread and the need for rigorous testing and tracing.
  • Orange: 10 to 24 cases a day per 100,000 people, showing “accelerated spread,” and stay-at-home orders are advised
  • Red: 25 or more a day cases per 100,000, meaning the county is at a “tipping point” and stay-at-home orders are necessary to contain the virus.
