Va. Code Ann. § 32.1-122.5

The Board of Health shall establish criteria to identify medically underserved areas within the Commonwealth. These criteria shall consist of quantifiable measures sensitive to the unique characteristics of urban and rural jurisdictions which may include the incidence of infant mortality, the availability of primary care resources, poverty levels, and other measures indicating the inadequacy of the primary health care system as determined by the Board. The Board shall also include in these criteria the need for medical care services in the state facilities operated by the Departments of Corrections, Juvenile Justice, and Behavioral Health and Developmental Services.
