Chronic rhinitis is a chronic inflammatory disease of the nasal mucosa. Clinically, it can be divided into simple, hypertrophic, and atrophic types. The treatment generally primarily involves the use of local medications, and typically does not involve the use of antiviral or antibiotic medications. Chronic rhinitis is not contagious. However, it is important to be aware of other conditions that can cause chronic rhinitis, such as tuberculosis-induced rhinitis and syphilitic rhinitis. These are not cases of the rhinitis itself being contagious, but rather the transmission of pathogens, so it cannot be simply stated that chronic rhinitis is contagious. Clinically diagnosed chronic rhinitis is definitively non-contagious.
