Influenza A virus subtype H1N1 treatments?

What is the other word for swin flu?

Influenza A virus subtype H1N1

Is the H1N1 bacteria?

H1N1 refers to a subtype of the influenza virus, not a bacteria. Influenza viruses can cause respiratory illness in humans and animals. It is important to note that viruses and bacteria are different types of microorganisms that can cause different types of infections.

Is it H1N1 or the H1N1?

It is a flu (influenza) virus. All flus are caused by viruses. A virus is categorized by type such as Influenza Virus Type A, Type B or Type C. Viruses are always changing and mutating, and flu viruses are especially quick in their ability to mutate. When a mutation occurs, they are categorized further as subtypes and then to a finder degree as strains. H1N1 is a subtype of Influenzavirus A. The pandemic swine flu is further identified as A-H1N1/09 indicating the specific mutation of A-H1N1 into the type that caused the pandemic of 2009. Beyond that, the individual strains are broken down and named usually according to the year they were isolated and the location where they were first found. See the related question below for more information on how viruses are named.

What is influenza A subtype N1H1?

H1N1 is a grouping of viruses that are subtypes of the Type A Influenza viruses. There are three types of influenza viruses that people get: Type A, Type B, and Type C. The type A H1N1 subtype of viruses are the most common cause of flu in humans (around half of all flu cases in 2006, for example). Some strains of H1N1 are also found to cause disease in other animals such as birds and pigs. The H1N1 subtype has been responsible for some major flu pandemics in recent history, for example, the post-World War 1 Spanish flu in 1918 and the 2009 swine flu pandemic (A-H1N1/09) were both due to Type A H1N1 virus subtypes.See related question below for more information about the virus that caused the 2009 Pandemic: Novel H1N1 Swine Flu also known as A-H1N1/09 virus.

Are all influenza Type A viruses the Swine Flu?

No, the pandemic A-H1N1/09 "swine flu" is just one of many Type A influenza strains. It is also one of many H1N1 flu subtypes. Besides Type A influenzas, there are also influenza Types B and C in humans.

What type of virus is the H1N1 classified as?

It is a Type A Influenza virus with RNA genome.Also called Swine Flu, the 2009 Pandemic Flu, 2009 Swine Flu, and A-H1N1/09.

Introduction of ah1n1 virus?

AH1N1 virus, also known as influenza A virus subtype H1N1, is a strain of the influenza virus that causes respiratory illness in humans. It gained global attention during the 2009 flu pandemic and continues to circulate as a seasonal flu virus. Symptoms of AH1N1 infection can range from mild to severe, with the potential for serious complications in certain populations.

Is swine flu H1N1 an antigenic shift or drift?

Swine flu H1N1 is considered an antigenic shift, as it resulted from a reassortment of genetic material from different influenza virus strains in animals. This led to the emergence of a new subtype that can infect humans.

WHAT IS Haue M1 N1?

Haue M1 N1, commonly known as H1N1, refers to a subtype of the influenza virus that caused a global pandemic in 2009. It is a strain of the influenza A virus and is often associated with swine flu. H1N1 can infect both humans and animals and is characterized by symptoms similar to those of seasonal flu, including fever, cough, and body aches. Vaccines have been developed to help protect against this virus.

Is Swine Flu a type of influenza?

Yes, it is the Influenza caused by the Type A H1N1/09 virus.

What was the last pandemic in history?

Swine Flu -_- The 2009 swine flu outbreak was an pandemic of a new strain of Influenza A virus subtype H1N1 identified in April 2009. It was thought to be a mutation (reassortment) of four known strains of influenza A virus subtype H1N1: one endemic in humans, one endemic in birds, and two endemic in pigs (swine).[58] A June 5th update by the U.N.'s World Health Organization (WHO) states that “69 countries have officially reported 21,940 cases of influenza A(H1N1) infection, including 125 deaths.” [59] -- Source-http://www.answers.com/topic/2009-swine-flu-outbreak --

What is the difference between H1N1 H1N2 H3N2 and H3N1 viruses?

Overview:H1N1, H1N2, and H3N2 are the only known Influenza A virus subtypes currently circulating among humans. All the subtypes listed in the question, i.e., H1N1, H1N2, H3N1 and H3N2 are the known subtypes of influenza A viruses that are endemic in pigs and create influenza in pigs, from which reassortants have formed new strains that can be infective to humans. H1N1 is the "swine flu" subtype of influenza, of which there are several different strains. This subtype is usually seen in humans and pigs. The better known reassortant H1N1 virus strain currently circulating is H1N1/09, the pandemic swine flu virus that caused the pandemic of 2009 and infected humans, pigs, birds, ferrets, dogs, and cats during the pandemic. There are several other less well known strains of the H1N1 subtype.H1N2 is a common flu in pigs in the Upper Midwest of the US. Until 2011, only one case had been known to occur in humans and that was in 2007 in Michigan. The second ever known case was found in an infant in December 2011 in Minnesota.H3N1 mostly only infects pigs.H3N2 is the subtype that produced a strain of flu that caused the Hong Kong Flu and another was the cause of the Fujian Flu, etc. In birds, humans, and pigs, there have been many new strains mutated and this subtype is becoming more prevalent in seasonal influenza.For background, the meanings of "H" and "N" in the nomenclature:Hemagglutinin: An important surface protein on the capsid (coat) of the influenza virus that is essential for the reproduction and the spread of the virus in the body in the lytic cycle of virus replication. This protein enables the virus to attach itself to a cell in the respiratory system or other mucous tissue and penetrate it to invade and use the host cell for reproduction. Referred to as the "H" in influenza viruses.Neuraminidase: An important surface structure protein of the influenza virus that is an essential enzyme for the spread of the virus throughout the respiratory tract. It enables the virus to escape the host cell and infect new cells. Referred to as the "N" in influenza viruses.See more about the lytic cycle and influenza virus nomenclature in the related questions below.Types of Influenza VirusesThere are three types of influenza viruses: Types A, B and C. Influenza A and B viruses cause seasonal outbreaks and epidemics of influenza virus infections each flu season. Type A causes all pandemics. Influenza type C infections cause a mild respiratory illness and are not thought to cause epidemics. Influenza A viruses are divided into subtypes based on the configuration of the two proteins on the surface of the viruses: hemagglutinin (H) and neuraminidase (N). [Not all H1N1 viruses are the same; not all H5N1 viruses are the same.....etc] There are 16 different hemagglutinin subtypes and 9 different neuraminidase subtypes. Influenza A viruses can be further broken down into different strains.Influenza B viruses are not divided into subtypes. Influenza B viruses also can be further broken down into different strains.Influenza A (H1N1), A (H3N2), and influenza B strains are included in each year's influenza vaccine. Getting a flu vaccination can protect against influenza A and B viruses. The flu vaccine does not protect against influenza C viruses.More information including how influenza viruses change: Drift and ShiftInfluenza viruses are dynamic and are continuously mutating, reassorting, and evolving. Influenza viruses can change in two different ways: antigenic drift and antigenic shift. Influenza viruses are changing by antigenic drift all the time, but antigenic shift happens only occasionally. Influenza type A viruses undergo both kinds of changes; influenza type B viruses change only by the more gradual process of antigenic drift. Antigenic drift refers to small, gradual changes that occur through point mutations in the two genes that contain the genetic material to produce the main surface proteins, hemagglutinin, and neuraminidase. These point mutations occur unpredictably and result in minor changes to these surface proteins. Antigenic drift produces new virus strains that may not be recognized by antibodies produced after exposure to earlier influenza strains.This process works as follows: a person infected with a particular influenza virus strain develops antibodies against that strain. As newer virus strains appear, the antibodies against the older strains might not recognize the "newer" virus to inactivate it, and infection with a new strain can occur. This is one of the main reasons why people can become infected with influenza viruses more than one time and why global surveillance is critical in order to monitor the evolution of human influenza virus stains for selection of which strains should be included in the annual production of influenza vaccine.In most years, one or two of the three virus strains in the seasonal influenza vaccine are updated to keep up with the changes in the circulating influenza viruses. For this reason, people who want to be immunized against influenza need to be vaccinated every year.Antigenic shift refers to an abrupt, major change to produce a novel influenza A virus subtype in humans that had not been currently circulating among people (see more information below under Influenza Type A and Its Subtypes).Antigenic shift can occur either through direct animal (poultry)-to-human transmission or through mixing of human influenza A and animal influenza A virus genes to create a new human influenza A subtype virus through a process called genetic reassortment or reassortant. Antigenic shift results in a new human influenza A subtype.A global influenza pandemic (worldwide spread) may occur if three conditions are met:A new subtype of influenza A virus is introduced into the human population.The virus causes serious illness in humans.The virus can spread easily from person to person in a sustained manner.
