Until recently, togaviruses were classified
in the same family as the flaviviruses. Modern molecular
techniques allowed virologists to separate the two families based
on gene expression. Togaviruses are divided into two genera:
Alphaviruses (18 members) and Rubivirus (1 member, Rubella).
The Alphaviruses are arthropod-borne, and Rubella virus, which
causes Rubella or "German Measles" is transmitted by
the respiratory route.
The Togavirus genome is:
10-12 KB in length (medium size)
The Togavirus capsid is:
T = 3
Composed of subunits of one protein
