Joe Fingas, Engadget:

As hinted earlier, Apple has started displaying COVID-19 testing sites in Maps. People in all 50 states and Puerto Rico can use Apple’s default navigation app to quickly find a place to get checked, whether it’s a hospital, urgent care clinic, pharmacy or dedicated testing site. The facilities also fall under a new “COVID-19 Testing” search category that’s prioritized alongside other essentials like groceries and healthcare.

To see this yourself, fire up Maps, tap in the search field, then scroll down past Recent Searches to the section labeled Search Nearby. COVID-19 Testing should be first on that list. Tap it, then testing centers near you should appear on the map.

Each location is marked with an icon:

• Hospitals are marked with a “+”
• Clinics and others are marked with a “*”
• Military locations are marked with a stethoscope icon

Or that appears to be the scheme. I’ve found exceptions, so it’s possible there’s more to it than that. If you know the specifics, ping me, I’ll update the post.
