The common cold is an acute, self-limiting viral infection of the upper respiratory tract involving the nose, sinuses, pharynx and larynx. The virus is spread by hand contact with secretions from an infected person (direct or indirect) or aerosol of the secretions and virus.1 The incubation period varies but is just under two days for rhinovirus.2 Symptoms, which generally relate to the infected mucosa, typically peak at 1–3 days and last 7–10 days, although they occasionally persist for three weeks.1,3–5 They include sore throat, rhinitis, rhinorrhea, cough and malaise.1,4 The severity and type of symptoms will vary among individuals and with different infective agents. For example, fever is common in children but rare and mild in adults.1 The incidence of the common cold declines with age.5–7 Children under two years have about six infections a year, adults two to three and older people about one per year.
