  1. There was no overall significant difference between healthy volunteer and chronic cough groups (Fisher’s exact test). Ns = not significant (p > 0.05, Fisher’s exact test). RSV = respiratory syncytial virus, hMPV = human metapneumovirus, PIV = parainfluenza virus, HCoV = human coronavirus, EBV = Epstein-barr virus, HBoV = human bocavirus, VZV = varicella zoster virus.
