Multiple students and staffers fell ill with a stomach virus at Sage Canyon School in Carmel Valley, prompting officials to clear the classrooms on Wednesday morning.
Sage Canyon’s principal, William Cameron, sent out a note to parents alerting them of the apparent stomach virus outbreak at the school.
Students were dismissed from classrooms at about 10:30 a.m. Wednesday, as custodians sanitized each room, the principal said.
In addition, a school open house set for Thursday night has been postponed until May 31.
One parent told NBC 7, his son, a kindergartner, had been vomiting the entire night before Wednesday and did not go to school today.
Another mom said she had heard from another parent about the illness.
"One of my friends who has a daughter in 5th grade, she mentioned to me, yes, my daughter yesterday was very sick. And apparently, a few others from her class," said parent Raquel Mussal.
Del Mar Union School District hasn't released how many students and staff were affected by the virus.
But students and parents have noted it appears to be mostly 5th graders, including half of one class.
Anoter parent NBC 7 spoke to said she's concerned and wants to know where the illness orginated from.
The school has reached out to the state’s Department of Health Services, which recommends all children with symptoms stay home from school until they’re free of symptoms for 48 hours.
