A postinfectious cough is a lingering cough that follows a respiratory tract infection, such as a common cold or flu and lasting up to eight weeks. Postinfectious cough is a clinically recognized condition represented within the medical literature.[1][2][3][4] Patients usually experience repeated episodes of postinfectious cough. The heightened sensitivity in the respiratory tract is demonstrated by inhalation cough challenge.[5]

Cause

One possible cause for postinfectious cough is that the receptors that are responsible for stimulating the cough during the respiratory tract infection are up-regulated by respiratory tract infection and continue to stimulate even after the virus has disappeared.[5]

Treatment

Postinfectious cough can be resistant to treatment, and usually goes away on its own; however, cough suppressants containing codeine may be prescribed.
