Hong Kong officials, say no new confirmed flu cases have been reported, in the last 24 hours.

Senior Food and Health official, Gabriel Leung.

"There has been no new confirmed case of human swine flu in the last 24 hours in Hong Kong, so therefore we still have only one confirmed case, the 25 year-old Mexican national, announced on May 1. His conditions remain stable in hospital."

Authorities kept 350 guests and employees inside the hotel, where the infected Mexican was staying.

But none caught the virus.

Again, Gabriel Leung.

"The reason is that because we have had a confirmed case and no evidence of any community transmission. The major public health objective at this point in time is to contain the epidemic, is to contain and completely interrupt the chain of transmission."

The government will ask the airlines, to waive penalties, for the guests, who were forced to change their travel plans.
