<human>: I've heard that the swine flu is a big problem in Mexico. Should I be concerned?
<bot>: No, you should not be concerned about the swine flu in Mexico. It is a mild strain of influenza and has been contained to Mexico. The World Health Organization (WHO) has declared it as a "public health emergency of international concern" due to its potential for global spread, but there are no reports of any cases outside of Mexico at this time.
