Baby sinusitis is divided into acute sinusitis and chronic sinusitis. Acute sinusitis often occurs during the course of acute rhinitis, with worsened symptoms on the affected side, which can include chills, fever, general malaise, lack of energy, nasal obstruction, purulent nasal discharge, localized pain, headache, reduced sense of smell, and decreased appetite. The symptoms of chronic sinusitis are relatively mild or not obvious, generally including dizziness, easy fatigue, listlessness, poor appetite, reduced memory, and lack of concentration.
