Exposure to indoor radon, a colorless, odorless radioactive gas, is thought to be the second leading cause of lung cancer and the leading cause of lung cancer among people who have never smoked. Testing your home or other normally occupied area is the only way to know for sure if an indoor radon problem exists. The Virginia Department of Health and your local health department have pulled together the following resources to help you learn about and test for radon in your home.

"Vector-borne disease" is the term commonly used to describe an illness caused by an infectious microbe that is transmitted to people by blood-sucking arthropods. Vectors typically become infected by a disease agent while feeding on infected vertebrates (e.g., birds, rodents, other larger animals, or humans), and then pass on the microbe to a susceptible person or other animal.  The most common vector-borne diseases in Virginia are carried by mosquitoes and ticks.


“Molds are types of fungi that are found everywhere. Molds reproduce by means of tiny spores; the spores are invisible to the naked eye and float through outdoor and indoor air.  Mold may begin growing indoors when mold spores land on surfaces that are wet.  Visible mold is an indication of excessive dampness; the source of moisture should be sought and corrected before the mold contamination is remediated. There are many types of mold, and none of them will grow without water or moisture. Molds are part of the natural environment.  Outdoors, molds play a part in nature by breaking down dead organic matter such as fallen leaves and dead trees, but indoors, mold growth should be avoided.  There is no practical way to eliminate all mold and mold spores in the indoor environment; the way to control indoor mold growth is to control moisture.”
