The common cold is an infection of the upper respiratory passages. The causative agents are the picorna viruses such as the rhinoviruses which comprise the largest single etiologic group, the adenoviruses, reovirus 1, and the myxoviruses. Generally speaking, the common cold refers to any undifferentiated upper respiratory infection. Rhinitis, laryngitis , "chest cold" and pharyngitis are terms used to refer to designated areas of infection.

The common cold is spread by direct person-to-person contact. Its frequency of occurrence peaks during the winter, and is correlated with sharp changes in temperature and humidity. Viruses from infected persons are airborne in droplet spray that is released into the air during breathing, snezing, talking, coughing and sneezing.

Symptoms of the common cold include: nasal discharge, nasal obstruction, sore or dry throat, malaise, headache, cough, sneezing, burning eyes andmucous membranes, and muscle aches.
