How do you catch H1N1 (swine) flu?

Spread of H1N1 (swine) flu can occur in two ways:

• Through contact with infected pigs or environments contaminated with swine flu viruses.
• Through contact with a person with H1N1 (swine) flu. Human-to-human spread of H1N1 (swine) flu has been documented also and is thought to occur in the same way as seasonal flu. Influenza is thought to spread mainly person-to-person through coughing or sneezing of infected people.
