The common cold is a viral infectious disease that infects the upper respiratory system. It is also known as acute viral rhinopharyngitis, or acute coryza. Being the most common infectious disease in humans, the cold is mainly caused by coronaviruses or rhinoviruses.
The human body can never build up resistance to all the viruses that can cause the common cold. It is for this reason that colds are so common and recurring. According to the CDC (Centers for Disease Control and Prevention) kindergarten children get an average of 12 colds per year, compared to adolescents and adults who catch about seven per year.
Experts say that going out when it is cold does not have any effect on the risk of catching a cold or spreading one. In addition, antibiotics do not cure a cold or speed up recovery.http://www.medicalnewstoday.com/articles/166606.php
