The common cold is a mild upper respiratory viral illness caused by several families of viruses (more than 200 subtypes of viruses), for example rhinoviruses, adenoviruses, human coronaviruses and respiratory syncytial virus. Rhinoviruses are the most common cause, accounting for 30 to 50 percent of common colds.1 

Initial symptoms include nasal discharge, nasal congestion/obstruction and a sore throat (dry or “scratchy” throat). Other symptoms include cough, sneezing, headache, fever (low grade, if present) and pressure or discomfort in the ears and face.1 It may also trigger asthma exacerbations. Colds typically last for 3 to 10 days, but may persist for longer, especially in smokers.1 

Preschool children have an average of about five to seven colds per year and adults an average of about two to three episodes per year.1 

Despite being a mild illness, the common cold is associated with a  significant economic burden as assessed by expenditures for treatment and by loss of productivity and subsequent loss of earnings.1 According to Sexton et al. “colds account for approximately 40 per cent of all time lost from jobs among employed people”.1
