The scientific name for swine flu is AH1N1pdm09. Inserted into the lipid membrane are spikes which are proteins actually glycoproteins because they consist of.

Influenza A H1N1 virus that is best known for causing widespread outbreaks including epidemics and pandemics of acute upper or lower respiratory tract infection.
Swine flu virus. That changed several years ago when a. The 2009 flu outbreak in humans that is widely known as swine flu is due to an apparently virulent new strain of influenza A virus subtype H1N1 that was produced by reassortment from one strain of human influenza virus one strain of avian influenza virus and two separate strains of swine influenza. President Gerald Ford announced a plan to vaccinate everyone in the country.
The virus can be transmitted to humans. The influenza A H1N1 virus is a member of the family Orthomyxoviridae a group of RNA viruses. Influenza viruses that commonly circulate in swine are called swine influenza viruses or swine flu viruses.
The influenza viruses usually responsible for swine flu are IAV subtypes H1N1 H1N2 and H3N2. Swine flu also called swine influenza hog flu or pig flu a respiratory disease of pigs that is caused by an influenza virus. Its a type of seasonal flu and is now included in the annual flu vaccine.
Swine influenza is a respiratory disease of pigs caused by type A influenza viruses that regularly cause outbreaks of influenza in pigs. H1N1 flu is also known as swine flu. The influenza virion as the infectious particle is called is roughly spherical.
Its called swine flu because in the past the people who caught it had direct contact with pigs. Swine flu is a respiratory disease caused by influenza viruses that infect the respiratory tract of pigs and result in a barking cough decreased appetite nasal secretions and listless behavior. Swine flu viruses may mutate change so that they are easily transmissible among humans.
The first flu virus isolated from pigs was influenza A H1N1 in 1930. Avian swine and other zoonotic influenza virus infections in humans may cause disease ranging from mild upper respiratory tract infection fever and cough early sputum production and rapid progression to severe pneumonia sepsis with shock acute respiratory distress syndrome and even death. 62 Some IAVs can be transmitted via aerosols from pigs to humans and vice versa.
Influenza A viruses in humans originate from birds and swine 3. Swine flu also known as the H1N1 virus is a relatively new strain of an influenza virus that causes symptoms similar to the regular flu. Type A is one of the three major types.
By the end of the year 40 million out of some 200 million Americans were vaccinated for the new strain but no pandemic appeared and public health credibility suffered. Swine flu viruses do not usually infect humans but rare human infections have occurred. Swine Influenza swine flu is a respiratory disease of pigs caused by type A influenza virus that regularly causes outbreaks of influenza in pigs.
Their introduction and subsequent adaptation to humans has caused global pandemics. In 1976 a late winter outbreak of swine flu at a military base in the USA led to fears of a devastating pandemic. Swine flu was the popular name for the virus which was responsible for a global flu outbreak called a pandemic in 2009 to 2010.
It is an enveloped virus that is the outer layer is a lipid membrane which is taken from the host cell in which the virus multiplies. Its often shortened to H1N1.
