Mexico City has lifted all measures introduced to curb the spread of swine flu, and changed its alert status to the lowest level, the BBC reports. "We can calm down now," said Mayor Marcelo Ebrard, telling residents they no longer have to wear masks. No new cases of the H1N1 strain have been reported in the city for over a week.
Schools, businesses, and public transportation will now return to normal in the city, which came to a near-total standstill at the height of the outbreak. Ebrard said that even though the alert level has been lowered, it was important for Mexico City residents to continue to remain vigilant, to keep conditions sanitary in places where crowds gather, and to maintain "a culture of health."
