Influenza B virus. Influenza B virus is the only species in the genus Betainfluenzavirus in the virus family Orthomyxoviridae . Influenza B virus is only known to infect certain mammal species, including humans, ferrets, pigs, and seals. [ 4][ 5] This limited host range is apparently responsible for the lack of influenza pandemics associated ...
Influenza, commonly known as " the flu " or just " flu ", is an infectious disease caused by influenza viruses. Symptoms range from mild to severe and often include fever, runny nose, sore throat, muscle pain, headache, coughing, and fatigue. These symptoms begin one to four (typically two) days after exposure to the virus and last for about ...

Polyvalent influenza vaccine is a type of influenza vaccine that provides immunity against more than one type of antigen. [1] In the second week after receiving the flu shot, the body's immune system is triggered by the antigens so the body starts producing antibodies. These antibodies help fight against influenza viruses.
The Influenza Genome Sequencing Project ( IGSP ), initiated in early 2004, seeks to investigate influenza evolution by providing a public data set of complete influenza genome sequences from collections of isolates representing diverse species distributions. The project is funded by the National Institute of Allergy and Infectious Diseases ...
Spanish flu (1918–1920) The 1918 flu pandemic, commonly referred to as the Spanish flu, was a category 5 influenza pandemic caused by an unusually severe and deadly Influenza A virus strain of subtype H1N1 . The difference between the influenza mortality age-distributions of the 1918 epidemic and normal epidemics.
H3N2 is a subtype of the viral genus Influenzavirus A, which is an important cause of human influenza. Its name derives from the forms of the two kinds of proteins on the surface of its coat, hemagglutinin (H) and neuraminidase (N). By reassortment, H3N2 exchanges genes for internal proteins with other influenza subtypes.
