China will not be hit hard by bird flu this fall
BEIJING (AFP) - China does not expect to be hit hard by deadly bird flu in
coming months, a top agricultural official said Tuesday, but a WHO expert warned
there could be more outbreaks as temperatures fall.
The government was stepping up vaccinations and strengthening surveillance of
poultry, Li Jinxiang -- the deputy director general of the Ministry of
Agriculture's veterinary department -- told a news conference.
"If our measures and vaccinations are successfully implemented, I believe the
situation will be very good," he told AFP on Tuesday.
World Health
Organization (WHO) expert said the virus is known to thrive in cold weather and
that vaccination alone could not prevent the spread of the deadly disease.
"We've certainly seen peaks of animal outbreaks and human outbreaks in the
winter time," said Julie Hall, a communicable disease expert at WHO's office in
the Chinese capital.
"We should be prepared this winter as the temperature drops. It's possible we
can see animal outbreaks and along with that human cases."
Changes in weather could also fuel the spread of the disease as birds, which
carry the virus, start migrating.
Agriculture ministry officials at the news conference vowed to continue an
ambitious drive to vaccinate all of China's poultry, despite warnings from
experts that vaccinations could mask the virus.
"The only way to prevent the spread of bird flu is to step up vaccinations,"
Zhang Baowen, the vice minister of agriculture, told reporters.
China embarked on a vast program to vaccinate its entire stock of poultry --
the largest in the world -- in November 2005 after several outbreaks across the
country.
Officials said their aim was to vaccinate almost the entire annual stock of
15 billion poultry this year.
However, vaccinated poultry can still carry the H5N1 bird flu virus and
spread it, experts have said. Hardly any of the human cases of bird flu in China
were preceded by poultry outbreaks.
"We hope that what they're doing is not just vaccinating but strengthening
the surveillance system, looking at the movement of animals," Hall told AFP.
"You cannot really rely on vaccination alone."
