Description

Rhinitis is the most prevalent nasal disease and is characterized by nasal mucous membrane inflammation. It can be infectious or noninfectious. Infectious rhinitis usually results from viral infection, which may trigger a secondary bacterial infection. There are three noninfectious rhinitis subtypes: seasonal allergic rhinitis, perennial allergic rhinitis, and perennial nonallergic rhinitis. This three-course suite discusses the causes of rhinitis as well as how it is diagnosed and treated.
