My child has cystic fibrosis and i am concerned about his grandfather who has cardiac failure and is often sick. should he wear a mask?

Perhaps: This depends upon what illnesses your child with CF has developed and whether they are ill when around granddad. It certainly will not hurt him to wear a mask, but may interfere somewhat with the relationship between he and the child.

CF infections: A child with CF may experience flare ups of their symptoms during viral illness or community acquired bacterial illness. It is best to stay at least 6 feet away to avoid inhaling any infected material. In addition, good hand washing, use of hand sanitizer and not touching your nose or face will help avoid infections. I hope that his grandfather feels better.
