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 ...
Respiratory syncytial virus (RSV), [a] also called human respiratory syncytial virus (hRSV) and human orthopneumovirus, is a virus that causes infections of the respiratory tract. It is a negative-sense, single-stranded RNA virus. [2] Its name is derived from the large cells known as syncytia that form when infected cells fuse. [2] [3]
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.
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).
