the common cold
the common coldthe common cold, also known simply as the cold, is a viral infectious disease of the upper respiratory 1 that primarily affects the nose. it is also possible that the throat, sinuses, and voice box get also 2. it is the most frequent infectious disease in humans. the average adult gets two to four colds a year, while the average child may get six to eight. they occur more commonly during the winter. these infections have been with humanity throughout history.
 
signs and symptoms
signs and symptoms may begin less than two days following exposure. they include coughing, sore throat, runny nose, sneezing, headache, and fever. people usually recover in seven to ten days. some symptoms may last up to three weeks. in those with other health problems, 3 may occasionally develop.
 
cause
well over 200 virus strains are 4 in the cause of the common cold; the rhinoviruses are the most common. they spread through the air during close contact with infected people and 5 through contact with infected objects. risk factors include going to daycare, not sleeping well, and psychological stress. symptoms are mostly due to the body's immune response to the infection rather than to tissue destruction by the viruses themselves.

hand washing;
not 11 the eyes, nose or mouth with unwashed hands;
