Again, I don’t think heating or cooling has an effect in these circumstances.
Didn’t most of the cruise ships have air conditioning turned on? Didn’t most of the nursing homes have heating turned on?
It is my view that the continued circulation of infected air at whatever temperature will increase the viral load to lethal proportions in any closed system.

It transmits through the air, not “droplets”.
In automobiles these days, you can set the AC and sometimes heat to either recirculate the cabin air or to pull in fresh air. I don’t know about cruise ships. Would they have that capability to pull in fresh air?
