Arteriviridae Explained

Arteriviridae is a family of enveloped, positive-strand RNA viruses in the order Nidovirales which infect vertebrates.^{[1] [2]} Host organisms include equids, pigs, Possums, nonhuman primates, and rodents. The family includes, for example, equine arteritis virus in horses which causes mild-to-severe respiratory disease and reproductive failure, porcine reproductive and respiratory syndrome virus type 1 and type 2 in pigs which causes a similar disease, simian hemorrhagic fever virus which causes a highly lethal fever, lactate dehydrogenase–elevating virus which affects mice, and wobbly possum disease virus.^{[3] [4]}

Structure

Member viruses are enveloped, spherical, and 45–60 nm in diameter.^[5]

Genome

Arteriviruses have a positive-sense single-stranded RNA genome.
