I think we need to do like China!!! With 0 Covid. LOL.
Seriously, I have been on 7 cruises since restart. Got sick on cruise with the most restrictions. People get infected even with total testing. Some report, some do not. Same like with a Flu, Noro etc.
I like how people now wash their hands because of Covid. At least noro isn't a thing anymore. 🙂
Unfortunately pharmacies are dropping COVID testing (and even last year scheduled tests were cancelled left and right), so we have to remember to order home tests every time, and hope that fluid is there. And that connections won't fail.
