Arbovirus (arthropod-borne virus) is defined as any virus that is transmitted to humans and/or other vertebrates by certain species of blood-feeding arthropods, mostly insects (flies and mosquitoes) and arachnids (ticks). Arbovirus is a descriptive term based on transmission by vectors with particular characteristics. It is not part of the International Committee on Taxonomy of Viruses classification of viruses (ie, it is not a species, genus, or family), which is based on the nature and structure of the viral genome
