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.

What is the common medical name of the flu?
'Avian Influenza' is not the scientific name, the scientific name is actually Orthomyxoviridae, Influenza Type A, subtype H5N1. The common names are: Avian Influenza, bird flu, and fowl plague.
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.
Is there a virus called h1n2?
H1N2 is a subtype of the influenza "A" virus - Hong Kong virus of 1968-69 winter and part of other preious influenza epidemics worldwide.
Which type of influenza is the worst?
Influenza A is generally considered the worst type due to its ability to cause more severe illness, pandemics, and higher transmission rates compared to Influenza B and C. Influenza A viruses have more genetic variability, allowing them to rapidly evolve and potentially develop resistance to antiviral medications.
Is the bird flu a virus or Bacteria?
Influenza A virus H5N1, is known as "bird flu". H5N1, is a subtype of the influenza A virus which can cause illness in humans and animals. A filtered and purified influenza A vaccine for humans is being developed.
What does h3n mean?
H3N is part of the influenza virus naming convention, with "H" representing the hemagglutinin protein and "N" representing the neuraminidase protein found on the surface of the virus. H3N typically refers to a specific subtype of influenza A 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.
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.
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.
What is a novel influenza?
The word novel used in this context means new or unusual. The 2009 pandemic swine flu H1N1/09 was initially dubbed the Novel Influenza by the CDC as a means of identification in communications since it was a brand new and never before seen subtype of influenza unnamed at the time. So if someone refers to novel influenza, they are likely currently talking about H1N1/09 swine flu.
In 1997 Hong Kong recorded the first instance of H5N1 subtype of this disease to jump from animals into the human population what disease is this?
It is the pathogenic avian influenza virus commonly known as 'bird flu'
