more swine flu

Now medical authorities have uncovered a total of seven people in Texas and California with a strain of swine flu. People that haven't been around pigs, so apparently human-to-human transmission. They are all OK - it seems mild. But the fact that the strain "is a hybrid that resulted from a combination of four different viruses -- one that typically infects people, one that originated in North American birds and two from pigs in Europe and Asia" demonstrates the dangerous side of flu, it's changeability.
