This simply shows just how important the Port of New Orleans is in the planet's economy, with a huge amount of shipping routes heading into and out of it. It is involved in the second busiest shipping area in the world, potentially bringing in international cargo or people that are infected with a hazardous disease. Also shown are the other super-ports of the world, of which New Orleans is a part of.

this illustration shows the level of vulnerability of materials and people in the Port of New Orleans, showing how it changes depending on the area that you are in. The left side is almost entire cargo, and it is handled by heavy machinery and mechanized equipment, with very little human interaction. The right side of the Port is almost entirely human oriented, with the majority of the cruise ship terminals here. This illustrates the different precautions and steps that need to be taken to ensure that the right kind of quarantined item (whether cargo or a human) is properly quarantined.
