The Infirmary at MMIS Karnal is well-equipped and is meant to take care of nearly four children in case of any health emergency. An attendant is always present to take care of the children. All the required medicines are there in the infirmary like the first-aid box, pain-killer medicines, sprays, height and weight measuring machine etc. We also invite expert doctors to our campus for regular checkups of the students especially for dental, eye and general health checkups.
