A busy day in the virus fight: Chief Executive Tung Chee Hwa exchanges views with Hospital Authority chief Dr William Ho, before visiting Lowu and seeing the operation of infrared thermal detectors and health posts.

All anti-SARS measures must be rigorous and up to the highest standard to further bring down the number of new cases of infection, the Chief Executive said today.

"Our next important step ahead is to bring down the number of new cases of infection to a single digit. We do not wish to see any of our frontline medical and nursing staff getting infected," he said.
