Millions of people do this every year without incident and Rio has great beaches that are definitely worth exploring if you have the opportunity. Much of the interesting and beautiful things in the world live in developing nations with developing nation problems.

In fact, other than the high viral load, what do Rio beaches have that isn't available in Miami (or Key West, or Puerto Rico)?
I don't really see much reason to venture outside US territory.
