Question: Why cant 2 CF patients kiss?

Cross-infection is the transmission of an infection from one person with cystic fibrosis (CF) to another, which means two people with the condition should never meet face to face.

Is cystic fibrosis contagious through kissing?

No. Cystic fibrosis is not contagious, even via kissing, because its a genetic disease. “It requires a mutation on the gene, one copy from the mother and one copy from the father,” says Wylam. (Having just one copy from one parent makes you a carrier without having the disease.)

What race gets cystic fibrosis the most?

Cystic fibrosis is most common among Caucasians. In the U.S., the chances of being a carrier of a CFTR mutation are: 1 in 29 Caucasian-Americans. 1 in 46 Hispanic-Americans.
