Mexico City authorities on Monday admitted they might have to “shut down” Mexico’s sprawling capital in an effort to combat an outbreak of swine flu that has so far claimed the lives of up to 149 people, according to official reports.
Marcelo Ebrard, the city’s mayor, said on Monday morning that the next step in trying to quarantine the virus, a hybrid of human and animal influenza strains that scientists have never seen, could be shutting down the public transport network.
