Picornavirales is an order of viruses with vertebrate, invertebrate, protist and plant hosts.^[1] The name has a dual etymology.^[2] First, picorna- is an acronym for poliovirus, insensitivity to ether, coxsackievirus, orphan virus, rhinovirus, and ribonucleic acid.^[2] Secondly, pico-, meaning extremely small, combines with RNA to describe these very small RNA viruses.^[2] The order comprises viruses that historically are referred to as picorna-like viruses.
