Influenza A virus (IFAV), Influenza B virus (IFBV) and Influenza C virus (IFCV)belong to the family Orthomyxoviridae and used to be included among the myxoviruses. All of their virions contain single stranded, negative sense, segmented (7-8), RNA (ssNSRNA) genome.Choose subtypes and segments to browse targeting microRNAs!
Influenza viruses are divided into 3 genera determined by the ribonucleoprotein (RNP) antigen:
A - This group is the cause of epidemics and pandemics and has an avian intermediate host (IH);
B - This group causes epidemics and has no IH;
C - This group does not occur in epidemics and causes mild disease.
In contrast to influenza A viruses, which infect humans and a wide range of other animals,
there is no evidence that influenza B viruses infect other hosts besides humans and seals[Pedro Pechirra et al., 2005].
