Poultry in Tibet market test positive for bird flu

http://news.xinhuanet.com/english/2007-03/06/content_5809988.htm

BEIJING, March 6 (Xinhua) -- Poultry from a market in Lhasa, capital of southwest China's Tibet Autonomous Region, have been found to be infected with the bird flu virus, China's Ministry of Agriculture (MOA) announced on Tuesday.

The birds had died in the market on March 1 and tests for the H5 virus by the National Avian Influenza Reference Laboratory were positive, according to the information office of the MOA.

Specialists and officials from the MOA and local government were taking measures to control the virus and prevent further infection in the area.

The measures included closure of the market, a cull of poultry in the market, disinfection of the area, inspections of poultry markets and monitoring of wild birds to prevent the spread of avian influenza.

Specialists believe the virus was introduced by wild birds migrating from east Africa to west Asia as no outbreaks of the disease had been reported in the source areas of the poultry.

Earlier this month three wild birds and two poultry birds tested positive for the H5 virus out of 325 poultry and 20 wild birds tested in Fujian province, where a woman who contracted the disease late last month is in a critical condition in hospital, according to authorities.

BEIJING : Poultry in the Tibetan capital Lhasa have tested positive for bird flu, state media said on Tuesday.

The H5 virus was confirmed after birds died at a market on March 1, Xinhua news agency said, quoting China's agriculture ministry.

The market has been closed and poultry culled to stop the spread of the virus, which experts believe was introduced by migrating birds.

The H5N1 strain potentially deadly to humans was confirmed at a farm near Lhasa in August 2005, prompting a cull of chickens.

Xinhua said three wild birds and two poultry birds tested positive for the H5 virus in the south-western province of Fujian this month, where a woman farmer is critically ill with H5N1.

China reports bird flu deaths in Tibet poultry

http://www.stuff.co.nz/3984778a12.html

BEIJING: China has suffered an outbreak of H5N1 avian flu among poultry in remote Tibet, while the virus also struck down thousands of wild birds in the region, state media and animal health monitors reported late today.

In a report submitted to the World Organisation for Animal Health (OIE), China's chief veterinary officer, Jia Youling, said the poultry died of the H5N1 strain of bird flu, which can be deadly to humans who have close contact with infected birds.

Jia reported that 680 fowl died in the outbreak in Chengguan Village near Lhasa, the capital of Tibet, and nearly 7000 other birds there were culled, according to the OIE website .

The poultry died on March 1, the official Xinhua news agency reported. It did not specify what kind of birds were infected. The government has closed the market and is also monitoring the health of wild birds, it added.

"Specialists believe the virus was introduced by wild birds migrating from east Africa to west Asia as no outbreaks of the disease had been reported in the source areas of the poultry," Xinhua said.

Jia also reported three separate outbreaks of H5N1 among wild birds in Tibet, including one that killed 28 migratory birds near Lhasa and two others that killed 2,579 and 57 wild birds elsewhere in the region.

The wild species infected included bar-headed geese, crows and hawks, according to the OIE.

There were also two outbreaks that killed 984 wild birds in Qinghai province, which neighbours Tibet, as well as two deaths among wild birds in northeast China's Liaoning province, Jia reported. His report gave no dates for the wild bird deaths.

Some scientists believe many outbreaks of bird flu in China's vast poultry sector have gone unreported until human infections in effected places have alerted health officials to the presence of the virus.

A woman farmer in China's southeastern province of Fujian has been infected with the H5N1 form of bird flu, China confirmed last week, the first human case in the country in about seven weeks. World Health Organisation officials have gone to the site of that case to investigate.

The Ministry of Agriculture said an investigation team it sent down to the woman's village found no trace of the H5N1 virus in poultry samples.

China has now reported a total of 23 human cases of bird flu, including 14 deaths, since 2003 and, with the largest poultry population and millions of backyard birds roaming free, it is seen as central to the fight against the virus.

China will vaccinate billions of domestic poultry over the next few months to guard against an outbreak of bird flu this spring, when the virus is at its most contagious, state media reported on Monday.

H5 Confirmed in Tibet
Recombinomics Commentary
March 6, 2007

Poultry from a market in Lhasa, capital of southwest China's Tibet Autonomous Region, have been found to be infected with the bird flu virus, China's Ministry of Agriculture (MOA) announced on Tuesday.

The birds had died in the market on March 1 and tests for the H5 virus by the National Avian Influenza Reference Laboratory were positive, according to the information office of the MOA.

Specialists believe the virus was introduced by wild birds migrating from east Africa to west Asia as no outbreaks of the disease had been reported in the source areas of the poultry.

The above comments describe an H5 outbreak that will almost certainly be linked to the Qinghai strain (clade 2.2) of H5N1. Although reporting has been limited, the above outbreak is likely to be linked to recent outbreaks in Kuwait, Pakistan, Afghanistan, and India.

Wild birds define a number of H5N1 transmission routes. The Qinghai strain is most easily tracked because its reported introduction into regions west of China began in the summer of 2005, but the sequences provide clear pathways which link isolates in western China, including Qinghai province.

Sequence data from the recent isolates would be useful.

The regional government launched an emergency plan after dead poultry from a market in the capital city, Lhasa, tested positive for H5 bird flu virus.

Officials moved to curb the spread of the disease after reports that 680 chickens died on Thursday, said Cai Bing, an official with the regional agriculture and husbandry department.

Samples of the dead poultry were tested in the regional center for animal epidemic and disease prevention and control, Cai said. The results were confirmed by the National Avian Influenza Reference Laboratory.

The market had two poultry vendors who had transported 8,100 chickens from other provinces on Feb. 27, including 430 sold to other markets in Lhasa before the infection was discovered, said Cai.

Regional authorities had the remaining 6,990 chickens slaughtered. The market has been ordered to remain closed for six months.

Measures such as disinfection of the area near the market and inspections of poultry markets had been adopted, said Cai.

The source of the infected chickens was still under investigation, said Cai, adding authorities were also tracing the 430 chickens sold to other markets.

Ninety-one people who had close contact with the chickens, including the two vendors and nearby residents, had been put under medical observation, Cai said.

Sales of live birds in markets within a 13-kilometer radius of the market have been banned.

Poultry transported to Tibet since Friday were required to undergo observation and quarantine before going to market, said Cai.
