A bacterial cause accounts for 2%-10% of acute rhinosinusitis cases.

Recommendations for Management of Acute Bacterial Sinusitis by the Infectious Diseases Society of America (IDSA):
Bacterial rather than viral rhinosinusitis should be diagnosed when any of the following occurs:
- persistent symptoms lasting at least 10 days, without improvement
- symptoms or high fever and purulent nasal discharge or facial pain for 3–4 days at illness onset
- worsening symptoms after an initial respiratory infection, lasting 5–6 days, has started to improve.
Empirical therapy should be started as soon as acute bacterial rhinosinusitis is diagnosed clinically.
Amoxicillin-clavulanate, instead of amoxicillin alone, is recommended for both children and adults.
Macrolides and trimethoprim-sulfamethoxazole are not recommended as empirical therapy, because of high rates of antimicrobial resistance.
