At one point yesterday, the streets of Mexico city and its 20 million inhabitants looked like a scene from a post-apocalyptic movie. After humans are gone, this is what megapolis cities might look and feel like: silent, empty; perhaps the sound of a few dogs barking; a stadium that normal holds 100,000 people, barren.
Officials are telling Mexicans to stay indoors and avoid large crowds to contain the spread of the disease. The streets are more or less back to normal today, thought many people are walking around wearing surgical face masks.
We all remember bird flu and SARS. Those global health scares that ended up well contained and much less of a threat to humans as the hype surrounding them suggested.
The numbers on this one are a touch more alarming. And the fact that swine flu is contagious from human to human is also worrying health officials.
We are live in Mexico with Karl Penhaul for the latest from the most affected swine flu area.
We'll also check out the U.S.'s response to the disease and what it's telling its citizens to do with a live report from the White House.
We are also live in New York, New Zealand, Switzerland, Great Britain and right here at the CNN Center with out medical correspondents for the latest on the outbreak.
That and the rest of the day's top news stories at the International Desk.
