The Martin County School District is telling 231 students from two high schools they should quarantine citing exposure to the coronavirus.
The district says the students at South Fork High in Stuart and Jensen Beach High will switch to remote learning for 14 days.
A district spokeswoman says those ordered to stay home include members of a swim team and travelers in a bus route.
Other schools in other areas of the state began to reopen this week as the number of people hospitalized due to COVID-19 declines statewide.
