Hong Kong hotel locked down amid flu fears

In Hong Kong, where the alert level has been raised to "emergency" after reporting its first case of swine flu, authorities are trying to keep the H1N1 virus from spreading through the metropolis of 7 million people through quarantine, stepped-up border measures and surveillance. The quarantine has extended beyond the single confirmed case, a 25-year-old Mexican man, to include more than 340 people.
