ELVERTA -- Three schools in the Elverta School District were closed Thursday after students came down with some type of gastrointestinal illness.
Elverta Elementary, Alpha Middle School and Alpha Charter High School were closed Thursday and Friday as the district cleans the campuses.
The illness wasn't disclosed but district officials said symptoms included abdominal pain, vomiting and diarrhea. County health officials were investigating the illness as a possible norovirus outbreak.
Approximately 40 students and five staff members were sickened.
A letter was sent home to parents notifying them of the illness. Parents were asked to tell the school if their child has similar symptoms.
