Mexico says there could be as many as 1 million swine flu cases nationwide during the winter, a steep rise from the current number of 21,264.
Health Secretary Jose Angel Cordova said Friday the situation at present is in "a very stable phase," with about 80 to 100 cases reported daily across Mexico. He says 184 deaths have been reported since the swine flu virus strain was identified in Mexico in April.
Flu cases normally tend to spike in the winter.
Cordova says authorities have drawn up plans to confront the possible upsurge in cases, possibly including more selective school closures in areas particularly affected. At the height of the outbreak in late April and early May, authorities closed schools nationwide.
