Orthomyxoviridae

Family of RNA viruses including the influenza viruses

Orthomyxoviridae (from Ancient Greek ὀρθός (orthós) 'straight' and μύξα (mýxa) 'mucus') is a family of negative-sense RNA viruses. It includes nine genera: Alphainfluenzavirus, Betainfluenzavirus, Gammainfluenzavirus, Deltainfluenzavirus, Isavirus, Mykissvirus, Quaranjavirus, Sardinovirus, and Thogotovirus. The first four genera contain viruses that cause influenza in birds (see also avian influenza) and mammals, including humans.
