So, if CV19 doesn't care if it's cold and dry or hot and wet, then it shouldn't surge in particular times or climates. Although, with global travel what it is in these times (when travel isn't locked down) that shouldn't matter much since it's almost always cold and dry somewhere, and folks are probably always going to/from those spots to other spots.

It could have a second wave due to seasonality, or due to control measures being lifted or failing - see Singapore etc
