What is Cystic Fibrosis:

Cystic Fibrosis is a genetic defect in a cell's ability to properly move water and salt in and out of the cell. Victims of the disease are born with it. Newborns are now screened with two simple tests to detect the disease at birth to try and prevent irreversible damage from the disease to the lungs, but only 65% of all cases are positively identified at birth.

Survivability and Statistics of Patients with CF

  • Cystic fibrosis is more commonly seen in Caucasians, where approximately 1 in 2500-3500 children are affected compared to 1 in approximately 17,000 African-Americans and 1 in 31,000 Asian-Americans.
  • Within Canada, studies have shown that approximately 1 in 25 Canadians are carriers of an abnormal gene associated with CF. These carriers, however, do not exhibit any symptoms.
  • Although CF used to be considered a fatal childhood disease, thanks to current drugs and treatments the average survival age is now 37.4 years, meaning those affected with the disease are typically still able to live through adulthood.
