Masks — Masks should be used in the following circumstances:
●Masks should be worn by healthcare workers caring for patients with respiratory secretions to protect healthcare workers from patients' infectious material (such as aerosols containing blood or body fluids).
●Masks should be worn by healthcare workers caring for patients undergoing sterile procedures (including invasive spinal procedures) to protect patients from respiratory aerosols generated by healthcare personnel performing the procedure.
●Masks should be worn by patients with respiratory secretions who are coughing if they leave their hospital rooms to limit spread of infectious secretions to other patients and to healthcare workers.
