Common cold
The common cold (also known as nasopharyngitis, rhinopharyngitis, acute coryza, head cold, or simply a cold) is a viral infectious disease of the upper respiratory tract which primarily affects the nose.Signs and symptoms include coughing, sore throat, runny nose, sneezing, and fever which usually resolve in seven to ten days, with some symptoms lasting up to three weeks. Well over 200 virus strains are implicated in the cause of the common cold; the rhinoviruses are the most common.Upper respiratory tract infections are loosely divided by the areas they affect, with the common cold primarily affecting the nose, the throat (pharyngitis), and the sinuses (sinusitis), occasionally involving either or both eyes via conjunctivitis. Symptoms are mostly due to the body's immune response to the infection rather than to tissue destruction by the viruses themselves. The primary method of prevention is by hand washing with some evidence to support the effectiveness of wearing face masks. The common cold may occasionally lead to pneumonia, either viral pneumonia or secondary bacterial pneumonia.No cure for the common cold exists, but the symptoms can be treated. It is the most frequent infectious disease in humans with the average adult getting two to three colds a year and the average child getting between six and twelve. These infections have been with humanity since ancient times.
