The common cold
Viral cause of the common cold1
|Virus||Estimated annual proportion of cases|
|Respiratory syncytial virus||5%|
The mean duration of the common cold is 7–10 days, but in a proportion of patients some symptoms can still be present after 3 weeks1.
1.Rhinovirus infections typically start with a sore throat, which is soon accompanied by nasal stuffiness and discharge, sneezing, and cough. The soreness of the throat usually disappears quickly, 2.whereas the initial watery rhinorrhoea turns thicker and more purulent.
2.Other symptoms associated with the cold syndrome include hoarseness, headache, malaise, and lethargy. Myalgia is an occasional complaint in patients with colds.
3.Fever is an infrequent finding during rhinovirus infections in adults, but it is fairly common in children with upper respiratory infections of any cause.
2.There are a host of nonprescription medications available to treat the complex of symptoms associated with the common cold including decongestants, antihistamines, antitussives, expectorants and analgesic-antipyretic.
3.Ibuprofen and acetaminophen are recommended antipyretic to be used in children which have good safety profiles.
