Influenza

Orthomyxoviridae (from Ancient Greek ὀρθός (orthós) "straight" and μύξα (mýxa) "mucus") is a family of negative-sense RNA viruses. It includes seven genera: Alphainfluenzavirus, Betainfluenzavirus, Gammainfluenzavirus, Deltainfluenzavirus, Isavirus, Thogotovirus, and Quaranjavirus. The first four genera contain viruses that cause influenza in birds (see also avian influenza) and mammals, including humans. Isaviruses infect salmon; the thogotoviruses are arboviruses, infecting vertebrates and invertebrates (such as ticks and mosquitoes).The Quaranjaviruses are also arboviruses, infecting vertebrates (birds) and invertebrates (arthropods).
