Sounds like you have got it pretty much bang onIt's more the travel rules that have helped I think. Since 1st Feb we closed down travel by people from China or those who had been to Wuhan, then we stopped travel from Italy, then more generally to anybody not a resident or citizen then everybody that wanted to come here was put into 14 days quarantine and now between states there are similar 14 day quarantine restrictions.
Knowing what we know now we should have shut down travel from the states and closed the ports to cruise ships earlier.
