To·ga·vir·i·dae

(tō'gă-vir'i-dē),
A family of viruses that includes two genera: Alphavirus, which includes eastern equine encephalitis, western equine encephalitis, and Venezuelan equine encephalitis virus, and Rubivirus, the rubella virus. Virions are 70 nm in diameter, enveloped, and ether sensitive; the capsid is of icosahedral symmetry, containing single-stranded positive sense RNA.

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.
