Catarrh and the common cold
Viral URTIs are otherwise known as the 'common cold'. They are the commonest diseases among humans. This limited acute mild catarrhal illness is usually a nasopharyngitis of 5 to 7 days duration. Symptoms include nasal discharge/congestion, pharyngitis, cough, and catarrh with minimal fever or systemic symptoms.
Most colds are caused by rhinovirus infection.3 Other frequent pathogens include, coronavirus, adenovirus, para-influenza virus, respiratory syncytial virus and influenza virus (A + B). Colds induced by different viruses differ primarily in their incubation period, ranging from 48-72 hours. Influenza virus has been shown to produce consistently more severe symptoms in all age groups when compared to rhinovirus infection3 and may be particularily debilitating in certain high risk patient groups
