  Introduction to Togaviridae
Dubbed Togavirus because of the "loose envelope" displayed in electron micrographs, the togaviridae were later shown to have envelopes that are quite tightly bound to the nucleocapsid.
The family Togaviridae was then split into three in 1984, joined by its cousins Flaviviridae and Pestiviridae (often not considered a true viral family).
Surprisingly, Togaviridae is less known for its arthrpod borne infectivity than for the single member of the Rubivirinae, Rubella.

 Encyclopedia: Togaviridae
The Togaviridae are a family of viruses, including the following genera: A virus is a small particle that infects cells in biological organisms.
The genome of the Togaviridae viruses is a linear, single-stranded RNA of positive sense that is 10,000-12,000 nucleotides long.
Togaviridae make use of a subgenome strategy to synthesize viral proteins.

 eMedicine - Eastern Equine Encephalitis : Article Excerpt by: Mohan Nandalur, MD
This infection is caused by an arthropod-borne alphavirus of the Togaviridae family.
The disease is uncommon in humans and is likewise associated with a high rate of morbidity and mortality.
EEE is a member of the antigenically similar family of viruses known as Togaviridae, which also includes western equine encephalitis and Venezuelan equine encephalitis.

Alphavirus is one of two genera in the family Togaviridae; Rubivirus (rubella virus), the other togavirus genus, is discussed in Chapter 55.
Alphavirus is one of the two genera in the family Togaviridae; the other genus (Rubivirus) has rubella virus (Chapter 55) as its only member.
Flavivirus, once classified in the Togaviridae, now constitutes one of three genera in the family Flaviviridae; the other two genera are Pestivirus and "Hepatitis C-like viruses".

 Togaviridae- Classification and Taxonomy
Alphavirinae, which bud through cytoplasmic membranes, are further distinguished from the rubivirinae, which bud through intracytoplasmic membranes.
The infection cycle of togaviridae begins when the virion is taken up into cellular vessicles by receptor-mediated endocytosis.
A pH drop caused by the merging of the carrier vessicle with a cellular lysosome digests nucleocapsid proteins and releases the genomic RNA to the cytosol where replication begins.
