👉 Virgulavirus is a type of virus that consists of a single, non-structural RNA genome enclosed in a capsid. It primarily infects and reproduce within the host cell's RNA-dependent RNA polymerase (RDRAP) machinery. Unlike other types of viruses, virgulaviruses lack an envelope or a lipid bilayer membrane. They are also known for their ability to cause respiratory infections, such as influenza, by adhering to and replicating inside host cells.
