Bacterial rhinitis is almost always secondary to underlying disease.

• A. True
• B. False
• C. Sometimes
• D. Not enough information

Answer: (A)

Bacterial rhinitis typically comes about when the nasal mucosa’s defenses are already compromised. The nasal lining relies on intact mucociliary clearance and local immune defenses to keep bacteria in check. When an underlying issue occurs—such as a viral upper respiratory infection damaging the mucosa, allergic inflammation with thick secretions, a foreign body causing obstruction, trauma, or systemic immunosuppression—these defenses are overwhelmed. That disruption creates an environment where bacteria can proliferate and invade, leading to bacterial rhinitis. Because this sequence (preexisting condition leading to a secondary bacterial infection) is so common, the statement is considered true. There are rare instances of primary bacterial rhinitis in severely immunocompromised individuals or unusual pathogens, but the usual pattern is that bacterial rhinitis is secondary to another disease.
