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.
