Big brother watching. My wife went to Greece for 10days with her friends. Within 12 hrs of her being home yesterday, Maine CDC calls and asks if she is quarantining for next 7days and whether she is vaccinated. Other than passport and covid test before flying out and covid test before coming home, which were negative, not sure how they knew she was home. There was no paperwork req'd for the 1st covid test stating if she was traveling to a foreign country, so we think it must be traced through the passport.
