Distinguishing between a viral and bacterial sinus infection can be tricky, but there are a few indicators. A viral infection often accompanies a cold, with symptoms peaking and gradually improving after a few days. Bacterial infections may present with more prolonged symptoms, typically lasting over 10 days without improvement, including a high fever, facial pain, and thick, colored nasal discharge. However, only a healthcare provider can provide a definitive diagnosis using clinical evaluation and, if necessary, specific tests.
