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.
The families within this order share a number of common features:
The evolution of picorna-like viruses seems to have antedated the separation of eukaryotes into the extant crown groups.[3]
The following families are recognized:[4]

Les Picornavirales sont un ordre de virus dont les hôtes sont des vertébrés, des insectes ou des plantes [2]. Ce groupe est constitué de virus qui ont un génome formé d'ARN simple brin à polarité positive (ssRNA).
