Scientists believe that a novel strain of swine flu virus emerged in pigs after two common swine influenza viruses from Eurasia and North America exchanged genes. Signs of swine flu in pigs include fever, coughing, sneezing and breathing issues. For humans, swine flu causes mild, flu-like symptoms such as fever, body aches and cough, from which most people recover without treatment. While there is a vaccine for pigs, there is currently no vaccine available to protect humans from swine flu.

3.  Scientists suspect that two influenza viruses
common in swine, one rooted in Eurasia and
the other in North America, came together in a
single cell within a pig. The two viruses
exchanged their genes like a couple of kids
swapping school clothes. The result was a
novel strain of virus, with, according to
scientists, two genes from the Eurasian virus
and six genes from the North American virus.

4.  Signs of swine flu in pigs can include sudden
onset of fever, depression, coughing (barking),
discharge from the nose or eyes, sneezing,
breathing difficulties, eye redness or
inflammation, and going off feed.

5.  it is not a cause for alarm. First, so far this is an
extremely uncommon illness affecting a very
small number of people in the United States, all
of whom had mild illness and recovered
without incident
 It’s an unpleasant upper respiratory illness
with systemic symptoms of fever, weakness
and body aches, that can knock you out for a
week, but from which you’ll recover, without
treatment and without having to go even to the
doctor, let alone to the hospital.

6.  The symptoms of swine flu in people are
expected to be similar to the symptoms of
regular human seasonal influenza and include
fever, lethargy, lack of appetite and coughing.
Some people with swine flu also have reported
runny nose, sore throat, nausea, vomiting and
diarrhea.

7.  Vaccines are available to be given to pigs to
prevent swine influenza. There is no vaccine to
protect humans from swine flu. The seasonal
influenza vaccine probably will help provide
partial protection against swine H3N2, but not
swine H1N1 viruses.
