This website is intended to give an introduction to the viral family Togaviridae.  Below is a quick summary of the key members, along with additional information provided by following the links.  Please enjoy.

Togaviridae is divided into two main taxonomic genera: Alphavirus and Rubivirus

Genus Rubivirus has only one member which causes disease in humans; Rubella virus.    This virus causes one of the "red rashes of childhood," and was common until the creation of the rubella vaccine. 

Alphaviruses are, as we in H&V like to call them, the rollar coaster viruses, "WEE EEE VEE!".  These viruses are transmitted by insect vectors, and are  the family which makes up group A of arboviruses (arthropod-borne viruses).

The 12 viruses in this group which are associated with human disease are:

  • Western Equine Encephalitis (WEE)
  • Eastern Equine Encephalitis (EEE)
  • Venezuelan Equine Encephalitis (VEE) 
  • Everglades Equine Encephalitis (EVE) 
  • Barmah Forest Virus (BFV)
  • Chikungunya Virus (CHIK)
  • Getah (GET)
  • Mayaro Virus (MAY)
  • O'nyong-nyong Fever Virus (ONN)
  • Ross River Virus (RR)
  • Semliki Forest Virus (SF)
  • Sindbis (SIN)
