BEIJING - CHINA reported 31 more cases of swine flu, bringing the total on the mainland Monday to 196 and Hong Kong, which tallies swine flu cases separately, said late on Sunday it had confirmed eight more cases, bringing the Chinese territory's total to 92.

The Health Ministry said on its website late on Sunday that the cities of Beijing and Shanghai have reported more cases, as did provinces in central, eastern and southern China.

The world's most populous country has quarantined travelers - including New Orleans Mayor Ray Nagin - on the slightest suspicion of contact with an infected person, and has increased surveillance of the virus with temperature checks on incoming passengers at airports.

Hong Kong's Health Department said in a statement late on Sunday that authorities found five more people who contracted the virus after recently returning from the United States, Philippines and Thailand.

The department says the other three cases were domestically transmitted, involving three 13-year-old girls at a school where the territory's first cluster of cases occurred.

There have been no reports of deaths.

The World Health Organisation said that as of last Friday, 74 countries have reported more than 29,000 cases of the virus, with 145 deaths worldwide. -- AP
