This is a multicenter, non-interventional point-prevalence study conducted in the US to determine the seroprevalence of antibodies to selected porcine viruses in pancreatic enzyme replacement therapy-exposed CF patients and in an unexposed control group with chronic medical conditions matched for age and geographic region of residence. Data collection includes demographic and medical history, pancreatic enzyme replacement therapy, transfusion history, and history of potential exposure to pig viruses. If a patient meets all the requirements of the study and provides a study specific informed consent/assent, a single blood sample is obtained as part of a planned standard-of-care blood collection.
