Honestly given how long a cargo ship takes from the EU to the USA and given that the crew of ships has basically no contact with the cargo crates this makes no sense at all...
The only think I can come up with is that this will allow Trump to show how bad it is that the USA is so much international dependent for certain goods and use that then to push through regulations to enforce more local production. But if it's really that it's quite crazy.
A normal travel ban on the other side will slow/reduce/eliminate cross infection between the EU and the USA which can be helpful to slow the spread. But then from all what I can tell it might be at a point where the slowing of the spread caused by EU/USA cross infection doesn't matter due to many more local sources of infection... Well we will see. At least during the ban he can't really put the blame of any increase onto the EU anymore as travel was cut.
