	Major Symptom
P	Facial P ain/pressure/fullness
O	Nasal O bstruction
D	Nasal purulence/discolored postnasal D ischarge
S	Hyposmia/anosmia (S mell)

*At least 1 symptom must be nasal obstruction or nasal purulence/discolored postnasal discharge. Thus, a diagnosis requires at least 2 PODS, one of which must be O or D.
Consider ABRS when viral URTI persists beyond 10 days or worsens after 5 to 7 days with similar symptoms [22]. Bacterial etiology should be suspected if sinus symptoms persist for more than 7 days without improvement [20].
