Manu Jain, MD, and Steven Shepherd, MPH and a long-time cystic fibrosis patient, join D. Kyle Hogarth, MD, FCCP, for this discussion of the debate on the policy of allowing only one adult patient with cystic fibrosis to attend any indoor events. Dr. Jain argues that risks are great enough to make this policy a good one. Mr. Shepherd argues that the concept is based on outdated ideas, the risks are very small, and that adults should be able to make their own choices on the risks they want to take.
