A virus is a submicroscopic infectious agent that replicates only inside the living cells of an organism. [1] Viruses infect all life forms, from animals and plants to microorganisms, including bacteria and archaea. [2] [3] Viruses are found in almost every ecosystem on Earth and are the most numerous type of biological entity.
The influenza virus spreads easily in the Northern Hemisphere winter due to climate conditions that favour the infectiousness of the virus. [27] Isolated weather events decrease the concentration of airborne fungal spores; a few days later, number of spores increases exponentially. [36] Socioeconomics has a minor role in airborne disease ...
Influenza B virus mainly infects humans but has been identified in seals, horses, dogs, and pigs. [23] Influenza B virus does not have subtypes like influenza A virus but has two antigenically distinct lineages, termed the B/Victoria/2/1987-like and B/Yamagata/16/1988-like lineages, [1] or simply (B/)Victoria(-like) and (B/)Yamagata(-like).
The virus is highly contagious and is spread by coughing and sneezing via close personal contact or direct contact with secretions. [52] Measles is the most contagious virus known. [20] It remains infective for up to two hours in that airspace or nearby surfaces.
