ABC.
A is the worst, causes pandemics and epidemics
B causes epidemics
C is minimally problematic
If you're talking about strains, you have 9 types of Hemagglutinin and 16 types of Neuraminidase. So H5N1 (swine flue from a couple years ago) has Hemagluttinin number 5 and Neuraminidase number 1
Yes, Swine flu is caused by a microscopic organism, a virus. The same type of microorganism also causes the common cold, Viral "stomach flu" (gastroenteritis), and the seasonal flu that comes around each year, plus many others. Viruses aren't really alive like bacteria and other types of microorganisms, but it acts alive since it can reproduce by using genetic material from the host animal's cells. See the related question below for information on the different types of microorgansims (microbes).
Viruses cause flu. The swine flu virus is the Influenza Type A, Novel H1N1 virus (aka A-H1N1/09 virus). It is a sub-microscopic organism. Human Influenza refers to one of the three major types of flu viruses ( Influenza types A,B, and C) that are endemic to the human population. These are in the taxonomic family orthomyxoviridae.The specific serotype/subtype of influenza virus that caused the 2009 swine flu pandemic is A-H1N1/09. The following very specific virus has been most prevalent and was the one that has been used in the manufacture of the vaccines:A/California/7/2009 (H1N1)-like virusViruses also cause the common cold, viral "stomach flu" gastroenteritis, and the seasonal flu that comes around each year, plus mumps, measles, herpes and many other common infections.Viruses aren't really alive like bacteria and other types of microorganisms, but they act alive since they can reproduce by using genetic material from the cells of the host.A-H1N1/09 is a new mutation of human virus, first seen in 2009, containing genetic material from different viruses combined : three types of pig flu viruses, one avian "bird" flu virus, and one human influenza virus. The novel nature of "evolved" or combined viruses (known as reassortants) make it unlikely an individual will have a natural immunity to it when it first mutates into being.Additional Note:Not all scientists classify a virus as a "microbe". Most of them do for lack of a better way to talk about them instead of "germ" or other less specific nomenclature. Unlike the other organisms called microbes, they are not living organisms. They are specialized groups of "cells" that perform functions working in an organized way, but they latch on to and break into a living host's cells and use the life, energy, and nutrients from the host in an almost parasitic way. The genetic material that they have stored inside themselves combines with that of the host's cells to cause the host cells to stop reproducing more cells like itself for the host. Instead the virus instructs them to start making duplicate viruses like the one that invaded the host instead.See the related questions below for more information about what caused the 2009 swine flu pandemic and what are the different types of microbes.
Both colds and flu are caused by viruses, with colds commonly caused by rhinoviruses and flu commonly caused by influenza viruses. Both types of viruses infect the respiratory system, leading to symptoms such as coughing, sneezing, and a runny nose.
The A and B in influenza are simply different types of influenza. * Type A: seasonal epidemics. This sub-type is based on changes in surface antigens hemagglutinin and neuraminidase. In humans subtypes H1-H3 and N1-N2 have circulated since 1918 pandemic (due to H1N1). In the last 3 decades the circulating types have been H3N2 and H1N1. * Type B: sporadic outbreaks (long term care facilities)
The Avian "Bird" flu is passed to humans by birds and their saliva and feces. Other forms of influenza that humans can get are also mutations of viruses that birds have had, some are from pigs (like swine flu) and many are from a combination of various swine, human, other, and bird flu strains that "reassort" in a host animal. For more information about how a new strain of the flu can be created through reassortant, see the related question below about what caused the 2009 Swine flu.
Yes, it is a definitive symptom in Avian Flu and a few other types of flu.
Swine flu is a flu very similar to the regular flu. Tamiflu is a medicine that you take when you have swine flu or other types of influenza.

Swine flu is caused by a new influenza virus that has genetic material from several different flu viruses that combined to form the new H1N1/09. The different types of flu involved in the development of the new virus are three types of swine flu (Asian, European, and American), avian "bird" flu, and human flu. Other than that relationship and that they are both influenza viruses, there is no other real relationship. Symptoms, mortality rates, and transmission are quite different between bird flu and swine flu.See the related question below for more informationon what caused this new type of flu.
Yes, and since the new flu that caused the pandemic in 2009 (H1N1/09 "Swine flu") there have been other new types identified (and even some new strains of avian flu have been identified) around the world. The viruses that cause the flu are mutating into new types of flu all the time. Cold viruses also mutate easily and quickly, this is a reason that vaccines can not be developed in time before they mutate again leaving the vaccine ineffective). Sometimes our immune systems have antibodies against older types of flu that will work to prevent the new types that are not that much different, but then other times the new influenza virus will have mutated into types for which our prior immunities will not be effective to prevent the new flu from making us ill. We will have to either get vaccines made as we did in 2009, or we will have to leave it to our bodies to make new antibodies that will block the new flu, but we will feel the symptoms of the flu in the interim.
It's a virus like other flu types.... Hence why we don't use antibiotics (anti bacterial) drugs to treat the flu. In more severe cases of flu, swine flu, bird flu doctors may prescribe anti viral drugs to combat the infection.
The H1N1/09 pandemic swine flu virus causes influenza. The symptoms are the same as most other types of flu. It has caused millions of people world-wide to become sick with the flu and thousands of deaths. It is a milder disease than some other types of flu, including the regular seasonal flu that, while not the same number of cases like the more easily transmitted swine flu, the seasonal flu typically causes the death of more of those infected than swine flu has so far. In the US there are approximately 36,000 deaths from the seasonal flu each year. See the related question below for more on the symptoms and death rates of swine flu.
A mixture of the standard Human Flu, Bird Flu and Pig Flu. This creates a new strain of flu called swine flu (Influenza A H1 N1).
Not all animals can get the types of flu that people get. Only a few types of animals have caught swine flu. There are different kinds of swine flu, not all of which people or other types of animals can catch. Some animals that have caught swine flu H1N1/09, the pandemic flu of 2009, are cats, dogs, ferrets, poultry and birds. But those that do catch swine flu spread it the same way people spread the flu to each other, through respiratory droplets from sneezes and coughs (this is why you should cover your mouth with a tissue or your elbow if you sneeze or cough). They also can get the flu by coming in contact with flu virus particles that have been released and are on surfaces that they touch. Most domesticated animals that did get the pandemic flu lived very closely with humans, like pet ferrets, dogs and cats living in people's homes while they were sick with the flu.
there are dozens of types. look em up <== (this answer is wrong) There are 3 types of flu called A, B and C. There are many different strains of each type.
