One possible cause for post-viral 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 after the virus has disappeared,

Treatment

Post viral cough can be resistant to treatment. Inhaled steroids may work in some patients. Post-viral cough is usually treated the same way as a viral cough.
