Help please! is cystic fibrosis something you can get in childhood?

No - Genetic defect: Cystic fibrosis is caused by a defective gene which results in alteration of a protein that regulates movement of salt and water in and out of cells. This leads to thick sticky mucus and very salty sweat. The thick mucus can block tubes both in the lungs and in the abdomen, especially the pancreas.

Words matter: CF will be recognized or diagnosed in childhood, so in a way you could say you get it then.However, the word use is confusing.You don't "get it" like you get a strep throat, you are born with the abnormal gene information that causes the disease.
