I hope not. In my opinion, the cabin verandas are divided/spaced sufficiently for outdoor spacing to make transmission very unlikely. I heard one epidemiologist explain outdoor settings by a smoking analogy. If someone is in a closed room smoking, over time the smoke fills the air of the room. Outside, you might smell the smoke, but it dissipates rather rapidly. The virus does the same, and wind would only increase that. Because of that, there almost certainly wouldn't be sufficient virus in the air between verandas to make someone sick. Maybe if someone directly sneezed from above and you happened to get actual droplets on you. But the odds of that seem rather low too.I got wondering about distancing on the ships if you have a veranda cabin. Obviously, if you’re inside your cabin with all the doors closed that’s not an issue. But, would there be limits on being able to access your veranda? Would they make sure that no one was occupying a cabin either side of you to create distance. Does the fact that the ship moves and the wind could carry a cough or a sneeze downwind create an issue?
Opening veranda doors would actually help reduce transmission. Schools in parts of Europe leave classroom windows open for that purpose.
