Inflame vs infect: Rhinitis is inflammation of the nose while sinusitis is inflammation of the sinuses. Both can be caused by either bacteria or viruses. Both can be caused by allergy or dysfunction of the nose or sinuses cause by chemicals or pollution. Both present differently depending on their cause. Infectious sinusitis can lead to inflammatory rhinitis. Infectious rhinitis can lead to inflammatory sinusitis.
