Keeping people safe from contracting communicable disease requires learning isolation technique. Whether you are a patient or visitor, medical seclusion cannot be effective without your cooperation. See the table on isolation technique for details on what to do.
As a nursing supervisor, I have often found doctors and nurses in the room of an isolated patient without the required gear. I would hand out the masks and gloves and remind them that they could jeopardize the health of other patients as well as their families. Breaches of isolation technique most often go unnoticed, so there should be constant reminders with signs, lapel buttons, and the like. You should speak up, too, for everyone's safety.
