MEXICO CITY (AP) - Mexico's health secretary says the number of new swine flu cases is stabilizing.

Jose Angel Cordova says he hopes that trend will continue and that a vaccine will be available in six months.

He says Mexico has 260 confirmed swine flu cases, including 12 deaths. But he says he'll stop updating his count of suspected cases and deaths, which had stood at about 2,500 and 168.

Top world health official Keiji Fukuda says everyone should remain cautious because numbers go up and down and viruses can return with a vengeance.
