Hillsborough County students and staff will be required to wear masks in schools for another 30 days, unless they opt out for medical reasons.
The school district voted to extend the mask mandate during Wednesday's regularly scheduled board meeting.
In a letter to parents and staff, the district says the mandate has resulted in a 58% percent decrease in cases since they reached their peak on Aug. 20 — two days after the mandate went into effect.
At that point, the district says 13,485 people either tested positive or were in quarantine.
That number was down to 5,647 as of Wednesday.
Hillsborough is one of several counties to defy Gov. Ron DeSantis' executive order that aims to block student mask mandates by local school districts. A judge overturned that order and said it can't be enforced, and the case is now under appeal.
The extension in Hillsborough will run through Oct. 15.
