An outbreak of the stomach flu prompted the closure of a private high school in the Sunset district Wednesday for deep cleaning of the campus.
St. Ignatius College Preparatory School officials announced the closure after an estimated 50 students called in sick Tuesday and another 90 kids were sent home from school, according to a letter from Principal Patrick Ruff that was posted on the school’s website.
Ruff said the campus will be closed and all events, including sports games, are canceled for Wednesday because the Public Health Department advised school officials it would be appropriate to “thoroughly” sanitize and “deeply clean” the campus.
Extra maintenance staff will be on hand to help with the cleaning.
The private school, located at 37th Avenue and Quintara Street, has an enrollment of 1,444. Tuition is $16,990 annually.
The health department was not immediately available for comment Tuesday night. The cause of the outbreak is unknown.
Several girls basketball players were absent from Tuesday’s game against Sacred Heart Cathedral due to the illness, St. Ignatius Athletic Director John Mulkerrins said.
“It’s all viral stomach flu,” Mulkerrins said. “It started three days ago with a couple of kids and spread pretty quickly.”
As of tonight, the boys basketball game between St. Ignatius and Sacred Heart is still scheduled to be played Wednesday at Sacred Heart, but St. Ignatius could be missing as many as seven players -- including all five regular starters.
Classes are slated to resume Thursday.
