The Pandemic 2009 A/H1N1 virus is an RNA/negative-sense ssRNA virus. The taxonomy/classification is:
- Order: Mononegavirales
- Family: Orthomyxoviridae
- Genus/Genera: Influenzavirus A
- Species/Type: Influenza A virus
- Serotype: H1N1
The nomenclature, for example, of the particular seed stock used for the 2009 Pandemic flu vaccine production was A/California/7/2009 (H1N1)v-like virus.
Virus type A/Geographic location California/Strain number 7/
Year of Isolation 2009/Subtype (H1N1)sense V-like(negative-sense ssRNA) virus
The Swine Flu viruses (including A- H1N1 2009 Swine Flu) are very similar in structure to all Influenza Type A viruses. They are also very similar in size to most viruses.
They are about 1/100th the size of bacteria. Most are "nano" size and too miniscule to be seen with a regular light microscope, so electron microscopes need to be used to visualize the virus particles (see electron photograph images in related link section).
When measured they have a diameter of 10 to 300 nanometers. The nanometer is equal to one billionth of a meter, or one millionth of a millimeter.

What is a H1N1 virus?
Swine flu is a respiratory disease caused by type A influenza virus that regularly causes outbreaks of influenza in pigs. The "classical" swine flu virus (an influenza type A H1N1 virus) was first isolated from a pig in 1930. Swine flu viruses cause illness in pigs, but the death rates are low. This new virus, although it is being called "swine flu," is not the same virus.
Is the Swine Flu caused by a virus or a bacteria?
It is caused by a virus called A-H1N1/09 influenza virus (aka swine flu).
What is A H1N1?

This new virus, although it is being called "swine flu," is not the same virus.
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.
Is Swine Flu a type of influenza?
Yes, it is the Influenza caused by the Type A H1N1/09 virus.
What is the h1n3 virus?
H1N3 is a subtype of the Influenza virus also known as the swine flu. If left untreated it might cause death.
How can you use the word swine as the subject of a sentence?
The swine ran over the cliff into the lake. His swine were inspected for traces of the influenza virus.
Is this the same Swine Flu of the 1970's?
No the A-H1N1/09 is a new strain of flu that has genetic material from three types of swine influenza viruses, avian flu virus and human flu virus. The "swine flu" in the mid 1970's was also an A-H1N1 influenza virus but quite a bit different than the pandemic strain.
Is the swine flue a fungus?
Swine Flu A-H1N1/09 is caused by a virus, not by a fungus. The virus is a Type A Influenza strain named A-H1N1/09 or also called the Pandemic Swine Flu virus among other names around the world.
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 pathogen causes influenza?
The signs and symptoms of the flu infection are:"Having Flu Symptoms Can Make Moaning Children A Nightmare":HeadacheFeverSore throatChillsMyalgias (pains)MalaiseCoughAnorexiaNasal congestionThe influenza virus causes influenza. There are a number of different subtypes and many have caused pandemics. These subtypes are A, B and C. Type A causes human "flu". This virus mutates rapidly and the vaccine must change quickly as well.A pathogen is anything that can produce disease or an infectious agent. A pathogen for influenza has a globular or spherical shape. Influenza is caused by a virus.
What is the definition of the Swine Flu?
Swine influenza (also called swine flu, hog flu, Mexican flu and pig flu) refers to influenza caused by those strains of influenza virus, called swine influenza virus (SIV), that usually infect (is endemic in) pigs.[2] As of 2009 these strains are all found in Influenza C virus and the subtypes of Influenza A virus known as H1N1, H1N2, H3N1, H3N2, and H2N3. Swine influenza is common in pigs in the midwestern United States (and occasionally in other states), Mexico, Canada, South America, Europe (including the United Kingdom, Sweden, and Italy), Kenya, Mainland China, Taiwan, Japan and other parts of eastern Asia.[2] Transmission of swine influenza virus from pigs to humans is not common and properly cooked pork poses no risk of infection. When transmitted, the virus does not always cause human influenza and often the only sign of infection is the presence of antibodies in the blood, detectable only by laboratory tests. When transmission results in influenza in a human, it is called zoonotic Swine Flu. People who work with pigs, especially people with intense exposures, are at risk of catching swine flu. However, only about fifty such transmissions have been recorded since the mid-20th century, when identification of influenza subtypes became possible. Rarely, these strains of swine flu can pass from human to human. In humans, the symptoms of swine flu are similar to those of influenza and of influenza-like illness in general, namely chills, fever, sore throat, muscle pains, severe headache, coughing, weakness and general discomfort. The 2009 flu outbreak in humans, known as "swine flu", is due to a new strain of influenza A virus subtype H1N1 that contained genes most closely related to swine influenza.[3] The origin of this new strain is unknown. However, the World Organization for Animal Health (OIE) reports that this strain has not been isolated in pigs.[4] This strain can be transmitted from human to human,[5] and causes the normal symptoms of influenza.[6] Pigs can become infected with human influenza, and this appears to have happened during the 1918 flu pandemic and the 2009 flu outbreak.
