When most people hear Primary Ciliary Dyskinesia (PCD), they think about the lungs. But PCD can affect another important part of the respiratory system: the sinuses.

Inside the nose and sinuses are millions of microscopic, hair-like structures called cilia. They normally work together to move mucus, trapped particles, and germs toward areas where they can be cleared. In PCD, these cilia may be 

Most of us never think about the microscopic cleaning system working inside our lungs every time we breathe. Millions of tiny, hair-like structures called cilia help keep the airways clean by moving mucus, germs, and debris out of the respiratory system.

For people living with Primary Ciliary Dyskinesia (PCD), that cleaning system doesn't

Let’s test your biology knowledge!

MYTH OR FACT?
"The modern name 'Primary Ciliary Dyskinesia' means that the microscopic, hair-like cilia in the lungs are completely paralyzed and cannot move at all."
Think you know the answer? Continue reading to find out.
For years, doctors and researchers couldn't quite agree on what to call

Imagine having millions of tiny cleaning crews inside your body—but those cleaning crews don't work properly. That's essentially what happens with Primary Ciliary Dyskinesia (PCD), a rare genetic condition that affects the tiny, hair-like structures called cilia.

PCD affects approximately 1 in 7,500 to 30,000 people. Because many of its symptoms can look like more common conditions, such as
