S Hyposmia/anosmia (S mell)
  1. *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.
  2. 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].
