Who Is at Risk for Cystic Fibrosis?

Cystic fibrosis (CF) affects both males and females and people from all racial and ethnic groups. However, the disease is most common among Caucasians of Northern European descent.

CF also is common among Latinos and American Indians, especially the Pueblo and Zuni. The disease is less common among African Americans and Asian Americans.

More than 10 million Americans are carriers of a faulty CF gene. Many of them don't know that they're CF carriers.
