“straight”; μ?ξα, mýxa, Greek for “mucus”) could be a family of negative-sense polymer viruses. It includes seven genera: Alphainfluenzavirus, Betainfluenzavirus, Deltainfluenzavirus, Gammainfluenzavirus, Isavirus, Thogotovirus, and Quaranjavirus. The orthomyxoviruses (influenza viruses) represent the genus myxovirus, that consists of 3 sorts (species): A, B, and C. These viruses cause respiratory disorder, associate degree acute disease with outstanding general symptoms. The orthomyxoviridae family, containing respiratory disorder -A, − B and -C viruses, are enclosed polymer viruses that cause higher tract infections characterised by fever, chills, headache, generalized muscular aching, and loss of appetency (Webster et al. (1985)). The family Orthomyxoviridae contains the genera Influenzavirus A, Influenzavirus B, Influenzavirus C, Thogotovirus, Quaranjavirus, and Isavirus. The name of the family comes from the Greek myxa, which means secretion, and orthos, which means correct or right.
