What is swine flu?
Swine flu - NHS ChoicesOpens new window
Swine flu, or influenza A (H1N1), is a respiratory disease that infects pigs and is caused by a flu virus. There are regular outbreaks of swine flu in pigs, which become ill but rarely die from the virus. Swine flu does not normally infect humans although this does occasionally happen when people have had close contact with pigs.
There is evidence that swine flu is spreading from person to person, which could lead to what is called a 'pandemic flu outbreak'. Pandemic flu is different from ordinary flu because it is a new strain of the virus that appears in humans and spreads quickly from person to person worldwide.
The World Health Organisation (WHO) is closely monitoring cases of swine flu to see how it develops.
