No proof bird flu spreading among humans

Airline, tourism shares slump despite assurances from WHO over outbreak that's killed six in China

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 so far has also seen 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 now 21 cases jave been confirmed.

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 4.1 percent and hotel operator Shanghai Jinjiang International Hotels Development fell 3.8 percent, while flag carrier Air China was off 2.6 percent. But medical stocks rose.

Concerns over the outbreak were also blamed for a tumble in Hong Kong stocks Friday; however, shares rallied 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 of Shanghai and two in the neighboring 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 Center.

Another official, Shu Yuelong, said that poultry infected with the H7N9 strain die more slowly than those with H5N1, giving the virus more time 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, which eventually killed about 800 people globally.

Users of China’s popular weibo microblogs have expressed skepticism 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.

The China Daily newspaper 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.
