My wife and I have just got home from a cruise to Norway on Britannia.
A couple of days in we were informed that staff also had chickenpox.
We were a bit suspicious and concerned it could be Covid.
Staff were walking along corridors with backpacks spraying in the air and were wearing masks.
They were constantly cleaning and having watched a show staff came in and started to spray again.
Having driven home my wife felt unwell so she did a covid test which was positive.
It may be a coincident but I am suspicious.
