What is Swine Flu?

Apr 27 2009 by Andy Richards, Birmingham Mail

It is a contagious respiratory illness in pigs caused by type A influenza viruses.

Outbreaks are common among pig populations but humans are very rarely infected.

How does it spread?

Humans can contract the virus if they have been in close contact with pigs.

It is also possible for the infection to spread from person to person. Experts believe it spreads through coughing and sneezing.

What are the symptoms?

They have included fever, fatigue, lack of appetite, coughing and sore throat.

How dangerous is it?

More than 80 people have died and thousands made ill, in Mexico in particular, although cases have also been reported in the US and New Zealand.
