I think Viking has stopped these practices because it is not sustainable anymore. It's incredibly expensive, time consuming, anxiety producing and caused people to be quarantined when many of them simply had bad cold symptoms. People were cancelling their cruises because of the possibility of this. Can we please now stop beating this dead horse?! Covid can be serious for some- so can other illnesses/ accidents etc. Cruises are petri dishes because you are living in close contact with many others thus the noro virus outbreaks you see from time to time. Traveling comes with all sorts of possible dangers. I can attest to masking being very effective against contracting covid. Keep wearing them especially if you are nervous about contracting covid.
