No proof China's H7N9 spreading between humans: WHO

   
BEIJING -- The World Health Organization said Monday there is no evidence China's bird flu is spreading among humans, but jitters over the outbreak that has killed six people saw airline and tourism shares slump.
   
China announced just over a week ago that H7N9 avian influenza had been
found in humans for the first time, and the number of confirmed cases has since reached 21.
   
Like the more common H5N1 variant which typically spreads from birds to
humans, experts fear such viruses can mutate into a form easily transmissible
between humans, with the potential to trigger a pandemic.
   
"Although we do not know the source of infection, at this time there is no
evidence of sustained human-to-human transmission," Michael O'Leary, the WHO's representative in China, told a news conference in Beijing.
   
"The human cases we know of are very serious. A large proportion have
died," he added.
   
Fears over the deaths sparked a slump in Shanghai shares, with hotel and
tourism shares leading the decline.
   
China United Travel, a tourism agency based in the eastern city of Nanjing,
slumped 4.16 percent and hotel operator Shanghai Jinjiang International Hotels Development fell 3.81 percent, while flag carrier Air China was off 2.63
percent and China Southern Airlines down 1.98 percent. But medical stocks rose.
   
Concerns over the outbreak were also blamed for a tumble in Hong Kong
stocks on Friday, however shares rallied in morning trade on Monday.
   
"The major cause of bird flu remains unknown and this will cause panic
among people and affect consumption, which may affect market expectations for the trend of the domestic economy," BOC International analyst Shen Jun said.
   
The outbreak has so far been confined to China's developed eastern region,
with four deaths in the commercial hub Shanghai and two in the neighbouring
province of Zhejiang. Other infections have occurred in Jiangsu and Anhui
provinces.
   
A Chinese expert said more H7N9 cases could be found in a wider area.
   
"We are tracking the source and cannot rule out the possibility of finding
the virus in other regions," said Feng Zijian, director of the emergency office
for China's disease control centre.
   
Another official, Shu Yuelong, said that poultry infected with the H7N9
strain die more slowly than those with H5N1, giving the virus more time in
which to infect people.
   
More than 365 people have died of H5N1 worldwide since a major outbreak in 2003, and it kills about 60 percent of people who develop it, according to WHO statistics.
   
The first deaths from H7N9 were not reported by Chinese authorities until
three weeks after they occurred, prompting criticism the initial announcement
was too slow.
   
But Chinese officials have said the delay in announcing the first results
was because it took time to determine the cause of the illness, and O'Leary
praised China's transparency, saying the WHO was "very satisfied and pleased with the level of information shared".
   
China faced condemnation a decade ago on accusations it covered up the 2003 outbreak of Severe Acute Respiratory Syndrome (SARS), which eventually killed about 800 people globally.
   
Users of China's popular weibo microblogs have expressed scepticism about official assurances. "Although there is no human transmission, why does the number (of cases) increase daily? This makes people scared," said user Li Xiao Lei.
   
The WHO said in a statement that it is possible the virus can spread to
humans from animals, such as pigeons.
   
Shanghai has culled more than 98,000 birds, banned trading in live poultry
and shut markets in a bid to curb the outbreak.
   
Nanjing city followed suit by banning live poultry trading while Hangzhou
culled poultry after discovering infected quail.
   
The China Daily newspaper on Monday called for "high alert" nationwide and urged stronger regulation of the poultry trade.
   
"The rules for transporting and trading of live poultry in cities should be
strengthened, because the bird flu can spread very fast in densely populated
cities," it said in an editorial. (AFP)
