It is not necessarily misleading, for a test positivity rate for SARS-COV-2 doesn’t have a perfect correlation with the infection prevalence or death counts for each of the viruses causing increased workplace and school absences in Scandinavia and coughing on SAS flights in recent weeks. That includes viruses that cause Covid-19, RSV, the flu and more.
Things would perhaps even be “healthier” on SAS TATL flights if SAS were to not so easily accept digital certificates of Covid-19 recovery from travelers and were to be more firm about mask requirements on these SAS flights, but alas SAS is SAS in being a reflection of its employees in the main who find Covid-19 to be “over” for reasons that have less to do with the infection scenes than with popular sickness with Covid-19 as a topic even in the background.
