Beginning this week, Google Maps app will display seven-day averages of new COVID-19 cases per 100,000 people. The chosen areas will show if cases are increasing or decreasing and be shaded with one of six colors to signify how many new cases were reported.

In a blog post. Google said the tool shows “critical information about COVID-19 cases in an area so you can make more informed decisions about where to go and what to do.”

Google is pulling data from three sources: Johns Hopkins University, the New York Times, and Wikipedia. They receive their data from the World Health Organization and other public or government health organizations. Information is available for all 220 countries that Google Maps works in.

The feature will soon be available on iOS and Android versions of Google Maps. To use it, open the app, press the layers button (two squares on top of each other) on the top right and press the “COVID-19 Info” button. That will reveal the color-coded app showing case counts.
