Influenza, commonly known as the flu, is an infectious disease of birds and mammals caused by a negative-sense, single-stranded RNA virus of the family Orthomyxoviridae. Typically, influenza is transmitted from infected mammals through the air by coughs or sneezes. Influenza can also be transmitted by saliva, nasal secretions, feces and blood. Infections either occur through direct contact with these bodily fluids, or by contact Rhinovirus (A/B/C) with contaminated surfaces. In people, common symptoms of influenza are fever, sore throat, muscle pains, severe headache, coughing, and weakness and fatigue. In more serious cases, influenza causes pneumonia, which can be fatal, particularly in young children and the elderly. The qPCR Kit for Human influenza A virus subtype (H1) genomes is designed for the in vitro quantification of H1 genomes.
