Japan confirms bird flu
outbreak
17 February, 2004
The bird flu outbreak has hit the poultry industry across Asia
Japan has confirmed its second outbreak of bird flu, dashing hopes that the
country was now free of the virus.
The farm ministry said chickens at a farm in Oita prefecture on southern
Kyushu island had died from avian flu.
It is not yet known if they died from the H5N1 virus - the strain that has
killed 20 people in Asia.
In Thailand, the virus has reappeared in eight provinces where mass culls
had been carried out and has also broken out in a new province.
Thailand had hoped to declare the country free of bird flu by the end of the
month, but the virus has now been found among fighting cocks in areas where
mass culls had been carried out.
UN warning
Six people have died from the virus in Thailand, while 14 people have died
in Vietnam, the only other country where the virus has spread to humans.
AVIAN FLU ALERT
First jumped "species barrier" from bird to human in 1997
In humans, symptoms include fever, sore throat, and cough
Types which threaten humans are influenza A subtypes H5N1 and H9N2
Q&A Avian flu
The United Nation's Food and Agriculture Organisation (FAO) said Thailand
had been premature in its optimism, warning that the outbreak could last for
several months.
"You cannot expect, seeing the extent of the outbreaks you had, that with
one go of stamping it out you have resolved the problem," the FAO's regional
animal health officer Hans Wagner told AFP news agency.
"You have to expect that you get secondary outbreaks or new outbreaks."
In Japan, officials had been preparing to declare the country free of bird
flu on Thursday if there were no new cases.
Until Tuesday, Japan's only confirmed case of avian flu this year was on a
farm in the prefecture of Yamaguchi, at the southern end of the main island
of Honshu.
On Monday, Vietnam confirmed another human case.
Tens of millions of chickens and ducks have already been slaughtered across
Asia as the outbreak has also hit China, South Korea, Cambodia, Taiwan,
Indonesia, Pakistan, Laos and Japan.
So far there is no proof that the virus can pass from human to human.
Health experts are worried that if the virus mixes with a regular human
influenza strain, it might create a mutant form that was able to pass
between humans, triggering a human flu pandemic.
