While some respiratory diseases such as pneumonia, asthma and allergies are well-defined in the popular imagination, colds, sinusitis and allergic rhinitis have inflammation of the airways in which it is easy to become confused. Let’s find out the differences of these diseases.
What is the difference between colds, sinusitis and allergic rhinitis?

The sinusitis, however, is a sinus infection which can be acute or chronic, and that occurs when the sinuses become swollen and inflamed. Sinusitis is usually caused by a virus, and often persists even after other respiratory symptoms resolved. In rare cases, fungi or bacteria can cause an infection of the sinus. Even allergies, nasal polyps, infections to the teeth, or a deviated septum can trigger sinusitis.
