An upper respiratory infection is a viral or bacterial infection that affects the nose, throat, sinuses, and larynx. These are the most common of all illnesses. The most familiar upper respiratory infections include the common cold, infection of the throat (pharyngitis), tonsils (tonsillitis), the air sinuses behind the nose (sinusitis), and the larynx or voice box (laryngitis).

Colds (known medically as upper respiratory infections) and influenza affect the air passages in the head, neck, and chest. For more information, see Cold or Influenza.
