It is not totally understood why there is a "flu season". It is clear that the flu spreads more and is more prevalent during the fall and winter, and it is assumed that is an environmental preference of the virus. Some studies suggest that it is the humidity and others that it is the temperature that the virus prefers in the colder months, and still others that it is the heat that the virus does not like and so it does not thrive or goes inactive when it is hot. The mechanism is not totally determined yet.
Obviously swine flu
I don't think scientists have figured that out yet...sorry.
the swine flu is caused by pigs, but eating the pork doen't spread the flu to your body. the flu is also contaigious by speading from people to people. the government is also thinking to shut down the school, it the flu case becomes worse! Swine flu was first started when little kids were messing with insides of a pig. Now it is highly contages.

No, Swine Flu is just one strain of the many flu viruses. Flu is an abbreviation for influenza. So Swine Flu is a type of flu, but all flu is not the swine flu, there are other kinds.

Yes. Just like other strains of flu, some people get very mild cases and others get it worse.
Just because your child has the swine flu, doesn't mean you do. Your child could get the swine flu even if you don't have it currently.
