Unlike most viruses, the shape of influenza viruses is highly variable; however, their surface is consistently covered with protein spikes .There are eight RNA segments which encode 10 proteins. Two of the proteins, heamagglutinin and neuraminidase, make up the surface spikes. These proteins are antigenic, and antibody to them is what protects humans from influenza. Haemagglutinin (H) is the protein by which the virus attaches to its host cell. At present, there are 15 immunologically and genetically distinct haemagglutinin subtypes. Neuraminidase (N) is an enzyme that plays a role in releasing virions from their host cell, promoting the spread of infection. Nine neuraminidase subtypes have been identified. Only three haemagglutinin and two neuraminidase subtypes are commonly associated with human infections.

What is influenza bacterium or virus?
It is a type of bacteria that can cause pneumonia. Although the name sounds like influenza, it is unrelated to the flu, which is caused by viruses and not bacteria.
Did fungi cause the influenza?
No. Influenza is a respiratory infectious disease caused by viruses.
Influenza is unicellular or multicellular?
Influenza is not a cell, it is a respiratory disease caused by a type of viruses, called influenza viruses. Viruses are not cells, they are sub-microscopic organisms that are non-living and disease-causing in humans, animals, and plants as well as in some bacteria.
What do the 'H' and 'N' stand for in influenza viruses?
hemaglutinin and neuraminidase, two surface glycoproteins of influenza that contribute the the virulence of the disease...
Why influenza A and influenza B cause epidemics but influenza C doesn't?
Influenza C viruses are also found in people. They are, however, milder than either type A or B. People generally do not become very ill from the influenza type C viruses. Type C flu viruses do not cause epidemics. Almost all adults have been infected with C but it just doesn't have the ability to cause epidemics and it doesn't fit the term epidemic.
What has the author Edwin D Kilbourne written?
Edwin D. Kilbourne has written: 'The Influenza viruses and influenza' -- subject(s): Influenza, Influenza viruses 'Influenza' -- subject(s): Influenza, Influenza viruses, Orthomyxoviridae
What viruses are stable and why?
stable viruses are very symtom, for example influenza. and viruses that are not stable, they are like animal viruses...
Does fungi cause influenza?
Fungi do not cause influenza. Viruses Cause influenza.
Are viruses responsible for influenza?
Yes, viruses are responsible for influenza. That's why antibiotics don't help when you have the flu.
What type of virus is influenza?
Influenzavirus A, Group v virus, Orthomyxoviridae, an RNA virus. Specifically:Order: MononegaviralesFamily: OrthomyxoviridaeGenus/Genera: Influenzavirus ASpecies/Type: Influenza A virusSee the related questions for more details.Orthomyxovididae = influenza viruses
What shape is the rhinovirus?
Like all influenza viruses it has a roughly spherical shape.
Where is influenza not found?
Influenza viruses are everywhere and are found any place animals or people are. There is no specific place that is totally without influenza viruses in the environment in the wild.
What is influenza bacterium or virus?
It is a type of bacteria that can cause pneumonia. Although the name sounds like influenza, it is unrelated to the flu, which is caused by viruses and not bacteria.
Who are the victims of Type A influenza?
Just about anyone who gets the flu. Most of the influenza viruses that cause disease in humans are Type A influenza viruses (but not all). Type A flu viruses are also what cause pandemics in humans.
Is the influenza virus cellular?
No. Viruses do not have cells.
What are any 2 viruses?
Influenza and HIV
What is the host of influenza viruses?
Birds and mammals.
