Not sure if most saw these reports over a month ago in NYC......
Large metro areas in Brazil are like NYC densities, but much more in poverty and squalid conditions.
Many living multi-generations cramped under one small roof.
These types of environments are ripe for explosive closed quarter spread world-wide.
I'm afraid international travel, particularly vacation travel, is going to be squashed for months, not just in and out of USA, but most all major 1st world nations. At least until these 3rd world nations still seeing or yet to see, spikes, get a handle on their nations. It's going to get worse in many high density 3rd world nations before it gets better in the coming months.
Last in, last out.
