The influenza virus group consists of three enveloped RNA members of the family Orthomyxoviridae:. influenza A, B, and C. . Influenza A . viruses are further classified into hemagglutinin (H) and neuraminidase. RNA virus. of the family . Orthomyxoviridae. that is responsible for the infectious disease . influenza. (or most commonly referred to as flu) in birds, various mammals (such as pigs) and humans. Typically, influenza is characterized by fever, sore throat, chills and other non-specific symptoms, it is a much more severe disease. It is spread around the world in seasonal epidemics and according to World Health Organization, these annual epidemics result in about three to five million cases of severe illness, and about 250 000 to 500 000 deaths.. Viruses are very small – smaller than the smallest cell.. They are usually surrounded by a capsid of proteins.. For replication, viruses rely on their host cells . ie. ., the cells they infect.. Most viruses exhibit a limited host range- they typically infect only specific types of cells of one host species.. McElroy AK, Erickson BR, Flietstra TD, Rollin PE, Nichol ST, Towner JS, et al.
