Symptoms of common cold

The term “common cold” refers to a mild upper respiratory viral illness. It is self-limited therefore it will go away without treatment. It is the most frequent acute illness in the United States. It is separate and a distinctly different illness than influenza, throat infection, bronchitis, sinusitis, pertussis, and allergic rhinitis.

The common cold is caused by various respiratory viruses, most commonly a rhinovirus. These viruses, which concentrate in nasal secretions, are easily transmitted through sneezing, coughing, or nose blowing. Adults have an average of two to four episodes annually, and young children may have as many as six to eight episodes.

Colds take one to three days to develop. They usually begin with a sore throat, followed by sneezing, sometimes a fever, a runny or stuffy nose, and cough. The flu can be much more severe, it usually starts suddenly and can affect the whole body.

The second set of symptoms are what prompt most patients to see a physician for relief. Symptoms usually peak around day 3 or 4 and begin to resolve by day 7. Nasal discharge, appearing at the peak of illness, can become thick and purulent.

Common cold viruses can be spread by three mechanisms:
* Direct contact,
* Indirect contact,
* Inhaling viral particles
