History

Etymology

The name "picornavirus" has a dual etymology. Firstly, the name derives from picorna- which is an acronym for "poliovirus, insensitivity to ether, coxsackievirus, orphan virus, rhinovirus, and ribonucleic acid". Secondly, the name derives from pico-, which designates a very small unit of measurement (equivalent to 10−12), combined with rna to describe this group of very small RNA viruses.; pico- + RNA + virus
