ST. PETERSBURG, Fla. — Students have begun returning to some Florida college campuses and some public school classrooms in rural districts have opened with new safety precautions in place as the state reports its lowest number of daily cases of COVID-19 in more than a month.

Robert Brown, a grandfather of five and foster father of another child, had mixed emotions about students returning to school. Brown lives in Hamilton County, located in North Florida on the Georgia border, and he was aware of news reports of students at Georgia schools contracting the virus after recent reopenings.

“It’s leaving me with some skepticism, because kids are kind of irresponsible,” Brown said.

One of his grandsons attended first grade in person on Monday. Another granddaughter was returning to a private school on Tuesday. His other grandchildren were doing online classes, including one with sickle cell anemia.

Brown and his wife also care for a 14-year-old foster daughter, who is doing online school.

“I’m worried,” said Brown, who is also a Hamilton County commissioner. “It’s a tough situation for everybody.”

Meanwhile, Florida reported 4,155 new coronavirus cases on Monday, the smallest daily caseload increase since the end of June.
