Is this believeable?
"You really have to look at trends - the daily figure or two days or three days doesn't really mean anything," said Malik Peiris, a microbiologist at the University of Hong Kong. "Really what you need to look at is maybe on a week, two-week basis. Is there a consistent trend downward? Then, one can feel more confident."
Hong Kong would appear to be heading in the right direction if new cases dropped into the single digits and stayed there, said Henry Niman, a Harvard University instructor who teaches surgery at Massachusetts General Hospital.
"It wouldn't mean Hong Kong was out of the woods, but it would be an indication things are contracting in Hong Kong rather than expanding," Mr Niman said. "It needs to continue going down and getting into single digits on an ongoing basis would be a good indication things are getting better."
