What is Radon? Radon is a gas that you cannot smell, taste or see. Radon forms naturally when uranium, thorium, or radium, radioactive metals, breaks down in rocks, soil and groundwater. People can be exposed to radon primarily from breathing radon in air that comes through cracks and gaps in buildings and homes.
The term 'prevalence' of Ehlers-Danlos syndrome usually refers to the estimated population of people who are managing Ehlers-Danlos syndrome at any given time. The term 'incidence' of Ehlers-Danlos syndrome refers to the annual diagnosis rate, or the number of new cases of Ehlers-Danlos syndrome diagnosed each year.
Ehlers-Danlos syndrome is a group of disorders that affect the connective tissues that support the skin, bones, blood vessels, and many other organs and tissues. Defects in connective tissues cause the signs and symptoms of Ehlers-Danlos syndrome, which vary from mildly loose joints to life-threatening complications.
