To·ga·vir·i·dae (tg-vîr-d)
n.
A family of RNA viruses that includes the causative agents of encephalitis, rubella, yellow fever, and dengue.

Togaviridae
a large family of viruses; presently two genera are defined: Alphavirus, which contains arthropod-borne viruses that cause eastern, western and Venezuelan encephalitis, and Rubivirus, which contains rubella virus of humans and is not arthropod-borne. Members of both genera have similar physicochemical properties. They are enveloped (toga?=?cloak) about 60 nm diameter, contain a single-stranded, plus sense RNA genome, replicate in the cytoplasm of cells and mature by budding through cytoplasmic membranes. Flaviviruses, which are also arthropod-borne, were once included in the family, but are now a separate family, Flaviviridae.
