It steals it from its host. A virus enters the cells of the host animal and changes the cell's DNA/RNA to make it stop doing what it usually does for the host and start working on making copies of the virus using the host's resources and energy. A virus is not a living thing, so it must have a living thing work for it to make replications in a "reproductive" process. The reproductive process of the influenza viruses is the Lytic Cycle. See more about that in the related questions.
What else can I help you with?
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).
Is the Swine Flu a fungus or a parasite?
Neither. The H1N1/09 "Swine Flu" is caused by a virus.
Is Swine Flu a bacteria?
No. The flu is caused by a virus, not bacteria.
Why did they rename Swine 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.
Pictures of Swine Flu?
Just go to a image search engine like Google Images and type in Swine Flu or Swine Flu Virus.
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.
Can Swine Flu mix with another virus?
Yes. In fact the way the H1N1 pandemic swine flu was formed by the mixing of a human flu virus, a bird flu virus and a swine flu virus in a pig. When two similar viruses that are infecting the same cell exchange genetic material this is known as reassortment. They go on to form a new 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.
What is A H1N1?
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 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.
Is Swine Flu hereditary?
No, the Swine Flu is not hereditary. It is a virus. It is caught in the same manner as the "regular flu" that goes around every year.
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.
