As medical discoveries go, influenza viruses were late to be isolated, mostly because of their sub-microscopic size.
In 1901 the hint of the existence of these infectious agents was found when it was proved that the "germ" was not bacteria by discovering that it passed right through a filter that would have trapped bacteria. The poultry virus that was called "fowl plague" at the time was not filtered out by the Chamberland filters like bacteria would have been, so it was known that something smaller was what caused the fowl flu.
In 1931 Richard Shope found the family of viruses that caused the flu in pigs, and the Orthomyxoviridae family of viruses that he discovered was named as the cause of the influenza.
In 1933 Patrick Laidlaw and a group at the Medical Research Council of the United Kingdom were able to isolate the flu virus from humans. But much was still to be known about these microbes.
Things started advancing more in the discoveries in 1935 when the first crystallized virus, that became known as the tobacco mosaic virus, was isolated by Wendell Stanley. His studies allowed much more to be known about viruses and their nature, including their non-cellular qualities.
Hello there! The first virus discovered was the tobacco mosaic virus or TMV. Have a good day! 😊
Martinus Beijerinck, in 1898, discovered the first known virus, tobacco mosaic virus.
The cold and flu virus cannot mutate together, but the cold virus can turn into a flu virus.
Yes flu is a virus
it was discovered in 1962.
Happy Birthday Joshi', the virus was first discovered in India in June 1990
Flu is caused by a virus. That's why antibiotics do not help when you have the flu.

the official name for the swine flu is the H1N1 virus. At first, it was believed that the virus came from pigs, but now that we are convinced it actually does not, we refer to it as the H1N1 virus. However, it is still very commonly known as the swine flu.
You can't. The only connection between flu vaccine and tobacco plants is merely that the flu and vaccines for the flu are made from influenza viruses and the first virus ever discovered in the 1880's was found on tobacco leaves in the form of the virus called Tobacco Mosaic Virus (TMV). It has been used since then in many medical and scientific microbiology studies and experiments to learn how to culture and grow viruses. To make flu vaccines, you must first culture and grow the virus. Tobacco Mosaic Virus was used in those studies and experiments because it was readily available, easy to culture and it is not infective to animals and that is how scientists learned how to begin to culture and grow flu viruses to make vaccines.
The scientific names for the virus strains that cause the flu are derived from the proteins on the virus capsid (coat), and usually some indication of the location from which the virus strain was first obtained or a type of known virus to which the new strain is similar, e.g., "Perth-like".In the naming convention of viruses, the protein classifications become part of the name as in H1N1; H for the haemagglutinin and N for the neuraminidase. There are different subtypes of viruses using the H and N nomenclature, for example the H5N1 subtype is the Avian (Bird) Flu and H1N1 subtype is the Swine flu.The common names usually are based upon where the virus was first discovered, e.g., The Hong Kong Flu, Fujian Flu, etc. or in what animal the virus is endemic, e.g., Swine Flu, Bird Flu, Horse Flu, etc.See the related question for more information on the naming of flu viruses.
A flu virus is a single strand of RNA.
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.
Avian Flu is caused by the virus like Flu virus in man. This virus has evolved with birds.
Influenza is the flu. The word "flu" is the abbreviated version of influenza. It is a virus.
The common seasonal flu ("regular" flu) is an RNA virus.

Many diseases were cured, as well as only just discovered, during the twentieth century. Some of the new diseases that were discovered include SARS, AIDS, Asian Flu, Hong Kong Flu and West Nile Virus.
It depends on the specific flu virus involved. See the related question below about the shape of the swine flu virus for more information.
Yes it was discovered in 1879?
The flu virus is pervasive in that it is a common virus which is spread from person to person generally in the cold months. There are several sub-categories of the flu virus, and the flu shot will usually contain 2 or three of these variations annually.
Flu is always caused a virus, not bacteria, so no flu epidemic will be due to a bacterial agent. This is true of the 1918 "Spanish Flu", it was caused by a virus.
How long does it take from contact with the flu virus to showing symptoms?
Yes, swine 'flu is caused by a strain of the influenza virus.
