Official Title: The Carrier Rates of Pseudomonas Aeruginosa in Family Members of Children With Cystic Fibrosis
Brief Summary: Pseudomonas aeruginosa (Pa) is the bacterium that causes one of the most consequential lung infections in people with CF. Many young children do not have Pa in their lungs but will become infected as they get older. The investigators want to learn more about how Pa is passed from person to person, especially to someone with Cystic Fibrosis (CF).
