Presidio Middle School in San Francisco closed Friday after more than 150 students reported having a stomach illness, officials said.

Approximately 155 students at the school reported symptoms consistent with gastroenteritis since Wednesday, according to officials with San Francisco Unified School District.

The school will close until Monday to sanitize all surfaces before students return, which requires about 48 hours.

“We understand that closing school is a burden on families and students, and we appreciate their understanding as we work to ensure the well-being of the school community,” Superintendent of schools Vincent Matthews said in a statement.

School officials said the symptoms are not consistent with coronavirus or anything other than gastroenteritis.
