Hundreds of kids are expected to stay home from one local school on Friday because of a "super contagious" stomach virus.
Approximately 120 children at Carroll Elementary School in Frisco became ill from the virus and it is spreading so fast even the school's nurse experienced symptoms.
Children at the school along Legacy Drive continue experiencing flu-like symptoms -- stomach cramps, diarrhea and vomiting, according to a note sent home to parents.
The latest news from around North Texas.
The virus "is wreaking havoc on our sweet children," the note said. "It does seem to be a short-lived virus which is good; however, it appears to be super contagious!"
Students said some classes are mostly empty.
"It just, like, happens," third-grader Joseph Carlson said. "Everybody has just been throwing up without knowing."
"It's crazy," said his sister, Meadow Carlson, a first-grader. "They're all going home."
Nine-year-old Jaden Hill said only seven students were left in his third-grade class.
"There was throw-up everywhere on the floors," he said.
The children described a long line of students outside the nurse's office -- and even she went home sick, they said.
Cleaning crews are disinfecting the school to try to stop the virus from spreading, administrators said.
NBC 5 saw a cleaning crew loaded with supplies go inside soon after school dismissed.
Sarah McKinney, a spokeswoman for the Denton County Health Department, said experts are monitoring the situation.
No other schools have reported a similar outbreak, she said.
