Stability of cough reflex sensitivity during viral upper respiratory tract infection (common cold)

Cough is among the symptoms most commonly associated with an acute, viral upper respiratory tract infection (URI), such as the common cold. Two previous studies incorporating capsaicin cough challenge methodology have demonstrated that cough reflex sensitivity is transiently enhanced during URI. These studies used single measurements of cough reflex sensitivity during the URI period. To our knowledge, no previous studies have included multiple...
