PLEASANTON, CA — A Pleasanton student's family member may have been exposed to a presumptive positive coronavirus patient, according to a letter sent from from Principal Soraya Villaseñor to the Valley View Elementary School community Thursday afternoon.

The family member is thought to have been possibly exposed to the virus at work and will self-quarantine with their family at home for 14 days, according to the district. The student was picked up from school when the district found out Thursday and students were moved to another classroom. No students, teachers or staff members have received presumptive positives — a term public health officials use to describe a patient who is exhibiting symptoms but has not yet been tested, said Pleasanton Unified School District Superintendent David Haglund in an interview.

Haglund said the district has notified all school principals of the matter and a letter was to be sent out to the PUSD community Thursday night. He encouraged people to wash hands frequently, stay home if they're sick and to visit this page on the district website for updates. "I'm a parent too," he said. "I know what it's like to have kids and worry about them."

The district is in communication with and will follow the guidance of the Alameda County Public Health Department. The district has disinfected the student's classroom and spaces the classroom visited, such as the library, multipurpose room and cafeteria, Haglund said. Rooms were disinfected out of an abundance of caution, he said. Custodians are prioritizing wiping down tables, keyboards, door handles and frequently touched spaces. The district is using a cleaning solution used during the norovirus outbreak last year that sits on desks overnight and attacks the virus, Haglund said.

The district is in touch with the Alameda County Public Health Department on a daily basis, he said. Flyers have been sent home about self-care. Some classrooms and schools have taken steps to do hand-washing demonstrations, and watch videos and share announcements about preventative measures.

Should the outbreak spread, the district will work with the county to determine what schools might need to be temporarily closed on a case-by-case basis.

"No one wants to close schools," he said.

PUSD officials have spent about 15 hours preparing for how it will respond if the outbreak worsens, he said. Officials are considering limiting field trips, graduation ceremonies and employee travel if the situation escalates.
