Post-viral cough is a persistent cough that remains after a viral infection of the respiratory tract, such as flu or colds, and lasts for more than eight weeks. It represents a recognized clinical case in European medical literature, but is not mentioned in American studies. One possible cause of this cough is that receptors responsible for cough stimulation, during respiratory tract infection, become more susceptible and continue to stimulate cough even when the virus has disappeared. Post-viral cough can be resistant to therapies. Normally it passes by itself with time, however, sedatives containing codeine are prescribed. It can often be caused by mucus accumulations and in this case may be helpful to nasal inhaled steroids. Voices correlateemodify wikitesto
