The problem with the Cruise ships is all were asymptomatic so they didn't know they had it. I spoke to the head of the Cruise line and got it first hand. My company is directly involved in that protocol. This spreads mask, no mask, vaccinated, no vaccination...... It has a faster incubation period so even being tested before cruising does not assure of a clean bill of health. Also, one of the biggest spreaders is getting off/on the ships at other ports for excursions. Talk about spreading the virus! The only good thing so far is it seems to be less lethal....and I know people have read other things on the lethal properties of it but that's my opinion and I'm sticking with it at this time. Not trying to debate or take up to much time on that issue. I agree about long haulers as they will increase in all probability.
