Mexico's top medical official told the AP that he's hopeful swine flu has begun to wane in his nation. "The fact that we have a stabilization in the daily numbers, even a drop, makes us optimistic," said Jose Angel Cordova. "We think we're on the right track." An official from the World Health Organization, however, cautioned that fluctuations are normal and that it's far too early to celebrate. In the US, meanwhile, the number of cases confirmed by the CDC rose slightly to 114 in 12 states, notes the New York Times.
