Easy, you are exposed to the germ is some fashion. It starts with something simple like an uncovered cough or sneeze and them someone touches an object. You pass by and touch that object and transfer that germ to another object, and so on. At some point someone touches an eye, nose or covers thier mouth with that germ that was picked up. Thus starts the flu.
People get ill with the flu because they have contracted an infectious influenza virus. Influenza viruses are ubiquitous and it is a normal and typical part of life to become ill from this.
Humans and birds can die from avian "bird" flu. Up to 60% of humans who get avian flu can die.
Swine flu began in China. Pigs (swine ) live with humans thus "swine" flu mutated and transferred to humans.
Swine Flu is a new strain of flu that originates from pigs and can travel to Humans. It started in Mexico
Flu has been around as long as man has been around. The Flu virus is spread by humans and by birds.
No, they didn't do it on purpose. They just got sick with the kind of swine flu they usually get but then that flu mutated together with the bird flu and some human flu strains into the Novel H1N1 (2009 Swine flu). Because pigs are very similar physiologically to humans, their genetic material was easier to change into a strain of flu that humans can get. This can only typically happen when pigs, humans, and in this case also birds are in very close physical contact, such as in a barn or barnyard. When you look at it this way, and since humans are responsible for keeping them in over crowded conditions, you might more correctly say that Humans are bad for starting the swine flu by keeping them all too crowded.
No a catch isn't an animal or human. Humans can catch the flu and polio. A lot of kids die from polio and the flu.
Pigs are no more to blame for swine flu than humans are for the common cold.
Not human flu, generally dog illnesses can't be caught by humans and vice versa.
See the related questions for information about the symptoms of bird flu. It has serious effects both on poultry and birds, but especially on humans. 50 - 60 % of the humans who have caught bird (Avian) flu have died from the disease. It does not spread easily from human to human, but the mortality rate is severe. Birds, especially water fowl and poultry, must be isolated or killed if they get this flu, which can drastically impact commercial poultry farmers and economies where these operations are major employers in the community.
no hey can give you flu
It is currently known to be possible for the following to be infected with H5N1, the highly pathogenic form of "Bird Flu" that humans can get: Pigs, birds (both wild and domestic), and humans.
Yes, it is a very deadly form of flu that kills 50 to 60% of those humans infected.
