Arenaviridae /Are·na·vi·ri·dae/ (ah-re″nah-vir´ĭ-de) the arenaviruses; a family of RNA viruses with a pleomorphic virion and a genome consisting of two circular molecules of single-stranded RNA. The single genus is Arenavirus.

area, pressure,
n an area of excessive displacement of soft tissue by a prosthesis.
area, recipient,
n the portion of the body on which a skin, bone, tooth, or other graft is placed.
area, relief,
n the portion of the surface of the oral cavity under prosthesis on which pressures are reduced or eliminated.
area, rest (rest seat),
n the prepared surface of a tooth or fixed restoration into which the rest fits, giving support to a removable partial denture.

area, supporting,
n the areas of the maxillary and mandibular edentulous ridges best suited to carry the forces of mastication when the dentures are in use. See also area, basal seat.
area, work,
n the entire space in which the dental hygienist moves and works while treating a patient. This includes the instrument tray and dental chair, unit, and light.
Arenaviridae
n a grouping of enveloped, helix-shaped RNA viruses implicated in a relatively benign form of meningitis (lymphoctyic choriomeningitis; severe encephalitic forms do occur rarely) that affects young adults.
Arenaviridae
a family of spherical or pleomorphic, enveloped, single-stranded RNA viruses containing host cell-derived ribosomes, e.g. Lassa fever virus, lymphocytic choriomeningitis (LCM) virus and Tacaribe viruses. The natural hosts are rodents.
