Statement from Miami-Dade County Mayor Carlos A. Gimenez on cancellation of
mass gatherings
...Therefore I have decided to suspend the operation of the Miami-Dade County
Youth Fair, the Miami Open tennis tournament, the MIA 5K run, and all major
events at the American Airlines Arena...
...In addition, I am recommending that small gatherings, if they're not
essential, also be reconsidered.
原则上不准大型聚会，也不建议小型聚会。
