Respiratory hygiene/cough etiquette evolved from observations made during the 2003 outbreak of coronavirus (CoV)-associated severe acute respiratory syndrome (SARS).1 Investigators concluded that transmission of the virus resulted from a failure to implement source-control measures when patients, visitors, and HCP with undiagnosed respiratory tract infections entered healthcare facilities.1 The new standard requires prompt implementation of source-control measures at the first point of encounter within all healthcare settings (Box A).1
Respiratory hygiene/cough etiquette is effective in decreasing the transmission of pathogens disseminated in droplets. Source-control measures apply to any person entering a healthcare facility with signs of illness, i.e., coughing, congestion, rhinorrhea, or production of respiratory secretions.1 In addition, the new standard requires educating HCP, patients, and visitors and the posting of signs with instructions about respiratory hygiene/cough etiquette (Figure 1).
