Miami, July 4 (RHC)-- The number of coronavirus cases in Florida jumped again as the mayor of the state's biggest city imposed a nightly curfew and rolled backed the reopening of entertainment venues to try to stem one of the most alarming coronavirus surges in the United States.

Miami-Dade County Mayor Carlos Gimenez announced an indefinite nightly curfew from 10 p.m. to 6 a.m. as the July Fourth holiday weekend began and halted the reopenings of venues, such as casinos and theaters that had been set for Friday.

"Let's celebrate Independence Day by respecting one another's right to life, liberty and happiness," Gimenez said in a video on Friday, citing the U.S. Declaration of Independence adopted on July 4, 1776.
