''Simarterivirinae'' is a subfamily of
enveloped,
positive-strand RNA viruses
Positive-strand RNA viruses (+ssRNA viruses) are a group of related viruses that have positive-sense, single-stranded genomes made of ribonucleic acid. The positive-sense genome can act as messenger RNA (mRNA) and can be directly translated i ...
