Due to the Department of Defense guidance on the use of face coverings, all patients and visitors over the age of two are required to wear a face mask or cloth covering while inside the medical facility. Exceptions are made for individuals with intellectual disabilities and those experiencing difficulty in breathing. Face coverings shall extend above the nose without blocking the eyes, and below the chin to cover the mouth and nostrils completely. Masks with an exhalation valve are prohibited. Face shields may be worn in addition to a face covering, but may not be used as a substitute.
