The toll from the swine flu epidemic appears to be stabilising in Mexico, with only seven more suspected deaths. Health Secretary Jose Cordova says the new virus is suspected in 159 deaths and 2,498 illnesses across Mexico. He called the death toll “more or less stable” even as hospitals are swamped with people who think they have swine flu. And he said on Tuesday night that only 1,311 suspected swine flu patients remain hospitalised, a sign that treatment works for people who get medical care quickly. Cordova said only 26 cases, including seven deaths, have been definitively confirmed to be swine flu. Meanwhile, Mexico’s pyramids and all other archaeological sites were put off limits nationwide and restaurants in the capital were closed for all but take-out food.
