One week after classes were back in session, a Tampa school district has 5,599 students isolating in quarantine. The students and 316 staff members have all either tested positive for COVID-19 or have been exposed to the virus, according to school officials.

Administrators within Hillsborough County Public Schools have now called an emergency meeting to discuss COVID-19 mitigation measures, including face coverings for all students and staff. The meeting will take place Wednesday afternoon.

"Isolation refers to individuals who have tested positive for COVID-19 while quarantine refers to those who have had close contact with a positive case," the school statement said, per NBC News.
