How does the Swine Flu infect your body?

Answer 1

If you are asking about the pandemic Swine Flu of 2009 (H1N1/09):

The virus comes in contact with your mucous tissues and is able to attach to those cells and infect you to begin the development of more viruses using your cells to do the work. The virus contacts your mucous tissue in different ways such as direct contact with an infected person. Or it can reach you by riding respiratory droplets that come out of your nose and mouth when you cough and sneeze (usually a 6 ft diameter around the sick person), hence the need to cover your nose and mouth when you cough or sneeze. If you touch where the droplets have landed, you can get the virus on your hands and then touch your nose, mouth or eyes introducing the virus to the mucous tissues. See more information in the related questions.


If you are asking about the swine flu that pigs get (H1N1):

This type of swine/pig flu does not normally infect humans. Only people with intensive daily contact with pigs, such as farmers, have a somewhat higher risk of catching this swine flu (aka pig flu). They get infected in the same way that other people get infected by 'human' flu varieties, by being exposed to coughs and sneezes and direct contact with other infected pigs.
