Common Cold

The common cold, also known as a viral upper respiratory tract infection.


More than 200 different types of viruses are known to cause the common cold. Because so many different viruses can cause a cold and new cold viruses constantly develop, the body never builds up resistance against all of them. Colds are a frequent and recurring problem.


The common cold is usually spread by direct hand-to-hand contact with infected secretions .Colds are most contagious during the first 2 to 4 days after symptoms appear, and may be contagious for up to 3 weeks. Your can catch a cold from person-to-person contact or by breathing in virus particles spread through the air by sneezing or coughing. Touching the mouth or nose after touching skin or another surface contaminated with a virus can also spread a cold.

Additionally, a cold virus can live on objects such as pens, books, telephones, computer keyboards, and coffee cups for several hours and can thus be acquired from contact with these objects.


The cold weather itself does not cause the common cold. Rather, it is thought that during cold-weather months people spend more time indoors in close proximity to each other, thus facilitating the spread of the virus. For this same reason, children in day care and school are particularly prone to acquiring the common cold.
