Chronic rhinitis primarily refers to the chronic inflammatory disease of the nasal mucosa. Clinically, it is classified into three types based on pathology: simple rhinitis, hypertrophic rhinitis, and atrophic rhinitis. From its classification, it can be seen that chronic rhinitis is not contagious. Clinically, it mainly manifests as nasal congestion, congestion of the nasal mucosa, nasal enlargement, etc. Therefore, it is not contagious. However, it is important to note that chronic rhinitis can sometimes acutely exacerbate under certain special conditions. During an acute exacerbation of chronic rhinitis, the nasal mucosa becomes highly congested, and secretion increases, which may be somewhat contagious under these circumstances. Therefore, analysis should be based on specific conditions. In summary, chronic rhinitis is not contagious.
