One Florida school district is facing a dire situation among students and staff just days after the school year began.

Hillsborough County Public Schools, which includes the city of Tampa, announced Monday that 5,599 students and 316 school employees are currently either in isolation or quarantine.

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 board will be holding an emergency meeting on Wednesday, in which the possibility of mandatory face coverings will be discussed, school officials said.

Georgia Gov. Brian Kemp is pleading with residents who have not been vaccinated to get the COVID-19 shot.

The state reported more than 14,000 new cases of the virus over the weekend, prompting Kemp to announce during a news conference Monday that state employees would be given the day off on Sept. 3 to get vaccinated ahead of Labor Day weekend.

The new surge in positive cases will not affect businesses, Kemp assured.

The average number of people being admitted to the hospital each day with COVID-19 in the U.S. has surged by more than 480% since the end of June, marking the highest number of patients seeking care in over six months.

Doctors are warning of the alarming rates of people entering the hospital with life-threatening conditions.

"What was more terrifying this time is that these people are drowning, they're drowning, and it is an awful thing to see,” Dr. Enrique Lopez, surgical tntensivist at Phoebe Health in Georgia said Monday in a new video message.”And you would look up on the monitor and their oxygen saturation would be near perfect and they would just sit there just starving for air just begging to breathe.”

Nationally, more than 83,000 Americans are currently hospitalized with COVID-19 nationwide. Several Southern states are experiencing their worst surge yet, with front line workers raising the alarm about overwhelmed ICUs, and patients waiting in hallways at some hospitals.

"They're just saying over and over again I can't breathe. I can't breathe. I can't breathe, and it was so different than it was last time," said Lopez. "Now, it wants kids, and those ICUs for those pediatric patients are filling up."

Likewise, as cases have increased, so have pediatric hospital admissions, experts say.

"Even though it's uncommon, it can be very severe and even life threatening in some cases," said Dr. Zac Aldewereld, assistant professor of pediatric critical care medicine and pediatric infectious diseases at the University of Pittsburgh. "And yet we have a vaccine to prevent it."
