Not to be confused with alphaherpesvirus. The alphaviruses are small, spherical, enveloped viruses with a genome of a single positive sense strand RNA. The total genome length ranges between 11,000 and 12,000 nucleotides, and has a 5’ cap, and 3’ poly-A tail. The proteolytic maturation of P62 into E2 and E3 causes a change in the viral surface. 3 junction influencing RNA template use during genome replication. This site is located at the base of a narrow cleft and is not readily accessible. This in turn affects RNA infectivity altering viral RNA production levels.

The E1 and E2 viral glycoproteins are embedded in the lipid bilayer. Single E1 and E2 molecules associate to form heterodimers. E2 heterodimers form one-to-one contacts between the E2 protein and the nucleocapsid monomers. Replication occurs within the cytoplasm, and virions mature by budding through the plasma membrane, where virus-encoded surface glycoproteins E2 and E1 are assimilated. These two glycoproteins are the targets of numerous serologic reactions and tests including neutralization and hemagglutination inhibition. The alphaviruses show various degrees of antigenic cross-reactivity in these reactions and this forms the basis for the seven antigenic complexes, 30 species and many subtypes and varieties. The E2 protein is the site of most neutralizing epitopes, while the E1 protein contains more conserved, cross-reactive epitopes.

A study of this taxon suggests that this group of viruses had a marine origin—specifically the Southern Ocean—and that they have subsequently spread to both the Old and New World. Barmah Forest virus is related to the Semliki Forest virus. Middelburg virus, although classified as a separate complex, may be a member of the Semliki Forest virus group. It seems likely that the genus evolved in the Old World from an insect-borne plant virus.
