We were on Equinox in December and few passengers wore masks, maybe about 5% We did wear them in elevators, theater etc. and noone commented. Only a few of the staff wore them, although some did. Our stateroom attendant didn't most days that we saw him, however I returned to the cabin one day while he was doing a cleaning during the cruise and he was masked up. There were no announcements made regarding covid cases. I did talk to one couple at the pool daily whose friend had 102 degree fever but I don't think they reported it to medical and just stayed in his cabin. His wife was out and about however as were their friends.
