The outbreak of swine flu is spreading across the globe, with cases confirmed from Mexico to Israel to New Zealand. Fears of a pandemic have prompted many nations, including ours, to ramp up security at land and air border crossings. As with any crisis involving national security, officials are considering all sorts of new technology to solve the problem. In Malaysia and Thailand, they're using high-tech thermal scanners to scan for swine flu. You pass through one at an airport, and it can determine if you've got a fever. So what technology are we using here at home? And is this going to help curb the spread of the flu?
