People who get chronic illnesses as children are living longer. When they turn 18, they switch from pediatric care to adult care. This can be a difficult change. Chronic Granulomatous Disease (CGD) is an inherited disease. It causes long-term, repeated infections. People with CGD are usually diagnosed when they are very young children. Researchers want to find out more about how young people with CGD handle the change to adult care. What they learn may make this easier for people with CGD in the future.
