The term upper respiratory infection is an inaccurate term used to describe acute infections of the nose, sinuses, pharynx, larynx, and bronchi.
Infection begins when a person's hand is infected with bacterial secretions and then touches his or her nose or mouth, or when the person inhales the bacteria containing the bacteria from an infected person when they cough or sneeze. After the entry of bacteria to the body exposed to a number of lines of defense, including physical, mechanical and immune, such as capillaries lining the nose and mucous lining of the upper respiratory system, and cells with cilia are surrounded by bacteria and transferred to the pharynx and from the stomach.
Most of the symptoms of upper respiratory infections include swelling in the affected area, redness, accumulation of fluids, secretions and a rise in temperature, but arises from the immune system's reaction to the body against bacteria, as these arise from the toxins produced by the bacteria.
