Post viral Cough is a condition that follows viral respiratory tract infections like Flu or Common cold . This usually happens because the receptors that were responsible for cough stimulation during previous infection are up reugulated and continue to stimulate after the virus is eliminated.
    This condition usually goes away on its own . However  increase in cardiac activity such as jogging ,running and other related cardiac activities help .
Cough suppressant drugs containing codeine may help .
