Answer 2

The 2009 swine flu outbreak originated in Veracruz, Mexico. Health workers traced the virus to a pig farm in this southeastern Mexican state. A young boy who lived nearby was among the first people to contract the swine flu.

Swine flu viruses are thought to be spread among pigs mostly through close contact and possibly from contaminated objects moving between infected and uninfected pigs. Infected swine herds, including those vaccinated against swine flu, may have sporadic disease, or may show only mild or no symptoms of infection.
