Nasal polyps accompanied by fungal infection generally are not contagious to each other. This disease is not infectious and does not have direct contagion. However, it is necessary to visit an ENT (Ear, Nose, and Throat) specialist promptly after symptoms appear. The patient will need to undergo a nasal endoscopy and a sinus CT scan to assess the severity of the condition. Most patients may need to consider surgical treatment, and after surgery, regular follow-up visits are required to monitor the effectiveness of the procedure. One to two weeks after surgery, nasal irrigation should be performed, which can be done using saline or physiological seawater to help reduce the retention of nasal secretions.
