(AP) The superintendent in one New Hampshire school district has canceled school as a precaution because an employee was advised to self-quarantine after traveling on a bus with a person diagnosed with the coronavirus.

Superintendent Susan Givens in Newmarket sent a letter to parents Sunday night. Givens said the employee, who is not a teacher, was contacted by the Centers for Disease Control Prevention. The agency, Givens said, asked the employee to self-quarantine because she traveled on a bus with a person who was just diagnosed with the coronavirus.  Givens said that neither the school employee nor her family are experiencing symptoms.
