According to a post on the RSU 24 website

Due to the extremely high number of staff at SMHS who are experiencing illness and will be out tomorrow, and the low number of available substitutes, there will be no school tomorrow, Monday, March 18th FOR HIGH SCHOOL STAFF & STUDENTS ONLY.
All other RSU 24 schools will be open.
