MIAMI — Mayors of some of the largest municipalities in hard-hit Miami-Dade County, gathered at a press conference on Monday and challenged Florida governor’s contention over the weekend that a spike in cases in the state could be attributed to an increase in testing and positive test results from people without symptoms.

They announced they will start requiring people to wear masks the moment they step out of their homes.

“This is a real spike. This is a real trajectory,” said Miami Beach Mayor Dan Gelber. “People can argue about the number of positives, being related to more testing, but they can’t argue with the percentage at now over 10%, which is what the CDC says tells you you have too much virus in your community.”
