I'm surprised Disney World has not been closed due to coronavirus.
Taking into consideration the Florida state population of 21 million people - this number does not include "snowbirds" nor tourists, and the number of people who have contracted coronavirus (28 people)
Here’s what we know about the coronavirus cases in Florida
it may seem like a lot of coronavirus victims for one state - as densely populated as Florida is in some areas like Sarasota County - unfortunately that number can rise due to permanent residents travelling (there is in fact a lot of money in the county where I live; I know four people who travelled to Italy last year, three people who travelled to France, one who travelled to Germany, France, and Poland).
Coronavirus won't do anything about the volume of traffic on Tamiami Trail (Rt 41) nor I-95.
