Togavirus, any of three genera of arthropod-borne viruses (arboviruses) of the family Togaviridae. Flaviviruses, once considered to be of the Togaviridae, are now designated as members of a separate family, Flaviviridae.

Alphavirus is a genus of RNA viruses, the sole genus in the Togaviridae family. Alphaviruses belong to group IV of the Baltimore classification of viruses, with a positive-sense, single-stranded RNA genome. [1] .

Togaviridae is a family of small, enveloped viruses with single-stranded positive-sense RNA genomes of 10–12 kb (Table 1. Togaviridae). Within the family, the Alphavirus genus includes a large number of species that are mostly mosquito-borne and pathogenic in their vertebrate hosts.

Postnatal rubella (German measles) is a generally mild, self-limited illness characterized by rash, lymphadenopathy, and low-grade fever. However, congenital rubella may cause a number of anomalies, depending on the organ system involved and gestational age.

Togaviruses are important veterinary pathogens, and are transmitted via mosquitoes. Some of them are zoonotic viruses, including Venezuelan equine encephalitis virus (VEEV). Rubella virus is the only member of togavirus family that causes …

Alphavirus is one of two genera in the family Togaviridae; Rubivirus (rubella virus), the other togavirus genus, is discussed in Chapter 55. The 27 alphaviruses are classified on the basis of antigenic properties.

Viruses of the family Togaviridae (togaviruses) are enveloped, positive-stranded RNA viruses of 60–70nm diameter, and include viruses of two genera, Alphavirus and Rubivirus. You might find these chapters and articles relevant to this topic. Alison …

The family Togaviridae comprises four genera: Alphavirus (with 26 species), Rubivirus (one species), Pestivirus (three species), and Arterivirus (one species). The main characteristics of the member viruses are: (i) the virus particles are spherical, 50-70 nm in diameter, including an envelope with …

A viral infection caused by any of the arboviruses of the Togaviridae family. It is transmitted by arthropods. Signs and symptoms include fever, headache, nausea, vomiting, rash, confusion, and seizures. [from NCI] Chikungunya: Epidemiology, Pathogenesis, Clinical …

In this article we will discuss about the structure and replication of togaviruses. The virus is enveloped and forms spherical particle of 65-70 nm diameter. It includes icosahedral capsid, which is made up of 240 monomers (Fig. 17.26). It has a triangulation number of (74).
