Influenza viruses are members of the family Orthomyxoviridae. [2] Influenza viruses A, B, C, and D represent the four antigenic types of influenza viruses. [3] Of the four antigenic types, influenza A virus is the most severe, influenza B virus is less severe but can still cause outbreaks, and influenza C virus is usually only associated with minor symptoms.
[23] [26] Influenza D virus is distantly related to influenza C virus. While cattle workers have occasionally tested positive to prior influenza D virus infection, it is not known to cause disease in humans. [1] [11] [12] Influenza C virus and influenza D virus experience a slower rate of antigenic evolution than influenza A virus and influenza ...
Influenza B virus is almost exclusively a human pathogen, and is less common than influenza A. The only other animal known to be susceptible to influenza B infection is the seal. [47] This type of influenza mutates at a rate 2–3 times lower than type A [48] and consequently is less genetically diverse, with only one influenza B serotype. [26]
Nancy J. Cox was born in 1949 and is a native of Curlew, Iowa. [4] She was educated at Iowa State University, graduating in 1970 with a degree in Bacteriology. [5] [4] Dr. Cox was awarded a Marshall Scholarship to study in England at the University of Cambridge at Darwin College, Cambridge, where in 1975 she earned a doctoral degree in virology.
Swine influenza virus (SIV) or swine-origin influenza virus (S-OIV) refers to any strain of the influenza family of viruses that is endemic in pigs. [2] As of 2009, identified SIV strains include influenza C and the subtypes of influenza A known as H1N1 , H1N2 , H2N1, H3N1 , H3N2 , and H2N3 .
Three virus families, Influenza virus A, B, and C are the main infective agents that cause influenza. During periods of cooler temperature, influenza cases increase roughly tenfold or more. Despite the higher incidence of manifestations of the flu during the season, the viruses are actually transmitted throughout populations all year round.

Viferon is a suppository of (non-pegylated [12]) interferon alpha-2b, ascorbic acid (vitamin C), and tocopherol (vitamin E) which was reported in two small studies to be as effective as arbidol. [13] [14] Another interferon alfa-2b medicine, "Grippferon", nasal drops, is used for treatment and emergency prevention of Influenza and cold. [15]
