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.
A Honor Society of Nursing (STTI) answered. The incidence rate for Ehlers-Danlos Syndrome (EDS) varies widely for the different types of disorders, but in general, affects approximately one in 5,000 people. One of the most common types, classical EDS, occurs once in every 10,000 to 20,000 people. The other most common type, hypermobility EDS, occurs once in every 10,000 to 15,000 people.
