Sign in the elevator lobby of the George Washington University medical practice's outpatient center, Washington, D.C.
Last week, similar alerts were handwritten in English with a Sharpie marker. Now they've been commercially printed in English, Spanish, and Chinese (both traditional and simplified characters). Looks like they're planning for the long term.
(Yes, that elevator emergency call button reads "code blue." But I'm confident that antedates the outbreak of the new coronavirus, however symbolically appropriate it may seem.)
