Abstract
The airborne route is a potential pathway in the person-to-person transmission of bacterial strains among cystic fibrosis (CF) populations. In this cross-sectional study, we investigate the physical properties and survival of common non-<i>Pseudomonas aeruginosa</i> CF pathogens generated during coughing. We conclude that Gram-negative bacteria and <i>Staphylococcus aureus</i> are aerosolised during coughing, can travel up to 4 m and remain viable within droplet nuclei for up to 45 min. These results suggest that airborne person-to-person transmission is plausible for the CF pathogens we measured.
