Plague Flags and Emojis

Still in use today, a yellow naval flag indicates a ship cleared infection. A ship with infected passengers, waiting out a 40-day quarantine (quarantine derives from Italian word for forty) hoists a checked "yellow jack" flag. (Both solid and checked flags are called "yellow jack".) Its use traces back to at least the bubonic plagues in 1300s and 1600s in Europe, if not earlier.

Trace-ER calls trace-EE and leaves a voicemail notifies trace-EE of test result and requests callback at [state approved number] with routing number sequence. "Please call me back at the tracing hotline, 1-8
