Swine flu – the facts

SWINE flu is a strain of the influenza A H1N1 virus.

Highly contagious, it and can be spread rapidly through tiny droplets emitted during a cough or sneeze. The virus can also be spread to anyone touching door handles and other surfaces up to 24 hours after initial contamination.
