Abstract
Calling a code is a common way to sound the alarm of an emergency. Many kinds of codes exist: for patients who arrest, for fires, and for babies who have gone missing, to name a few. This article proposes a new code, Code Flu, which will alert staff, patients, cooperating and referring agencies, and members of the community that they are to operate under the preplanned pandemic flu plan. Suggestions for developing a Code Flu plan are outlined.
