Cystic fibrosis is a genetic disorder that cannot be prevented. But people who have cystic fibrosis can help prevent more serious health problems such as lung infections by:

• Keeping immunizations current. Children who have cystic fibrosis should have all the recommended immunizations in addition to pneumococcal and flu shots. For more information on the recommended schedule of immunizations for children, see the topic Immunizations.
• Not smoking and avoiding secondhand smoke.
• Using airway clearance techniques, such as postural drainage and chest percussion.
• Eating nutritious, high-calorie foods.
• Having regular checkups and frequent tests, and following their treatment plan.
• Seeking care from a cystic fibrosis specialty treatment center, if possible.

In addition, parents of a newborn who has been diagnosed with cystic fibrosis should care for the baby at home and avoid placing him or her in day care for at least 6 months to 1 year, if possible.
