The common cold is medically referred to as a viral upper respiratory tract infection. Symptoms of the common cold may include cough, sore throat, watery eyes, nasal congestion, runny nose, and sneezing.ecause so many different viruses can cause the common cold and because new cold viruses constantly develop, the body never builds up resistance against all of them. For this reason, colds are a frequent and recurring problem.
And the evidence is not very powerful that you can. A cold is caused by an infection with a virus and then the symptoms that we all experience are really produced by the body's response to the viral infection. And it turns out that the body's response is very important in helping you get over the cold within five to seven days.
