I agree with all of the comments that you must assume that everyone has coronavirus, and clean and vacate your space accordingly.
I do believe that due to international travel restrictions (arrival quarantines, closed borders, visa discrimination, etc.), there will be an uptick in local travel. At my places in St. Lucia and Atlanta, I found that a good bit of the guests were local couples looking for a romantic getaway, regional visitors, or returning immigrants who don't want to stay with family during their visitor. I foresee these types of travel will resume as more businesses/attractions open during the warmer months, along with the expanded access for testing.
St. Lucia's economy is too dependent upon tourism to keep the borders closed, and will start accepting international flights on June 4. They will remove the 14 day quarantine requirement for arrivals, and will heavily depend up the results from the testing performed at the departure and arrival airports to screen visitors to the island.
