More Than 500 New Swine Flu Cases In England

The new cases include 225 in London and 158 in the West Midlands – two of the main hotspots.

It takes the total number of cases in England to 3,364, the Health Protection Agency said.

The rise came as officials announced on Thursday that London and the West Midlands will now adopt a policy of outbreak management.

This means swine flu cases will be clinically diagnosed rather than being confirmed by laboratory results.
