With the flu season ramping up in Australia along with new variants of Covid-19, just in time for our world cruise to begin, what I would like to see is Princess clamping down on inconsiderate people who insist on carrying on as usual, sneezing and/or coughing heavily over and around other passengers and, of course, not wearing masks. With the medallion technology it would be very easy to identify those people and pass on their details to the Medical Centre who should then require those people to be tested for flu and Covid, and the testing should be covered by Princess. If positive they should be required to isolate for several days (typically 5-6 for Covid) but medical treatment would be optional. If negative to flu and Covid but still showing symptoms they should be asked to isolate as well, and they don't then they should have to test every day at their own cost until their symptoms disappear.
