Hillsborough and Miami-Dade counties became the third and fourth school districts in Florida to adopt stricter mask mandates Wednesday, a day after school boards in Broward and Alachua counties faced threats of severe penalties for defying Gov. Ron DeSantis' administration. The Hillsborough County school board, which oversees the state's third-largest district with more than 206,000 students in the Tampa area, voted 5-2 to adopt a 30-day mask mandate with a medical opt-out for students, teachers and staff. Most school districts have adopted optional mask policies or given options to parents to easily opt out of requirements. The new policy takes effect Thursday. "I think there may be some friction with parents wishes related to the new plan. We're going to help coach them through this," said Addison Davis, Hillsborough County Public Schools Superintendent. "And it's for it's only 30 days and while may be uncomfortable, I get it, no one wants to wear a mask for those who aspire not to. But sometimes we've got to do something that's greater for the community." Also Wednesday, the Miami-Dade school board passed a similar mandate with a medical exemption by a 7-1 vote. In Miami-Dade, Florida's largest school district with 334,000 students, a task force of medical experts recommended students be required to wear masks when they return to classrooms next week. Superintendent Alberto Carvalho agreed and pushed for the new rule at Wednesday's meeting.
