Welcome to the home of Picornaviruses
hosted by The Pirbright Institute

The family Picornaviridae currently consists of 147 species grouped into 63 genera (as of March 2020). Five new genera, each containing a single species, were proposed in August 2020. A further six species have also been proposed in existing genera. The number of species in each genus is shown in brackets (+ those newly proposed).

The Picornaviridae pages have been updated to reflect the new taxonomy approved by the ICTV in March 2017 (Adams et al., 2017), February 2018 (King et al., 2018), February 2019 (Walker et al., 2019) and March 2020. Thus the taxonomy is based on the ICTV 10^th Report Chapter - Picornaviridae (Zell et al., 2017) and the ICTV Master Species List 2018.

Full Classification of the family Picornaviridae:

Realm: Riboviria
Kingdom: Orthornavirae
Phylum: Pisuviricota
Class: Pisoniviricetes
Order: Picornavirales

An important note on names and orthography:

• ICTV approved genera and species names are shown in italics, e.g. Hunnivirus A (except in menus and page titles because of technical difficulties).

• Proposed (i.e. a proposal has been submitted to the ICTV) genera and species names are enclosed within double quotation marks, e.g. "Acmevirus A".

• Candidate genera and species names are enclosed within single quotation marks, e.g. 'Acmevirus B'.
