Bird flu detected in Uthai Thani

Another bird-flu outbreak among fowls was confirmed in Uthai Thani.

Sakchai Sriboonsue, the director-general of Livestock Department, said lab test confirmed that fowls, which died earlier in the province, caught avian flu virus.

He said his department had already took all necessary actions to control the outbreak before the lab results came out.

On Sunday, the department also confirmed that the bird flu outbreak among fouls was detected in Sukhothai.http://www.nationmultimedia.com/brea...ewsid=30088373

Health Offices across Thailand Step up Bird Flu Monitorings


Health Offices across Thailand Stepup Bird Flu Monitorings
Health offices in several provinces have started spraying anti-bird flu disinfectant and cleaning up areas suspected to be at risk of contracting bird flu while campaigning for more public awareness about the danger of the H5N1 virus.

Sukhothai Governor Yothin Samutkheeree has chaired a meeting on a special campaign aimed to promote the clean-up and the disinfection of bird-flu virus in all risk areas. The campaign followed hot on the heel of an order from the Livestock Department for all the provinces to safeguard its residents and fowls from from H5N1.

Yothin added that officials have already set up checkpoints to control the transport of fowls and issued a ban on cock fight matches across the province.

He is assuring residents of Sukhothai that the bird-flu situation is now under total control.

In northeastern Mukdahan, Livestock Department officials are closely monitoring the situation and are on a lookout for any new outbreak of bird flu.

They have also collaborated with local health volunteers to educate the public about the deadly virus and set up checkpoints along the routes that connects Mukdahan with adjacent provinces, to control the movement of fowls.

Mukdahan authorities are asking locals to immediately report any suspicious and sudden deaths of fowls, and not to touch or consume the fowls suspected to be infected with H5N1.

Meanwhile, in Nakhon Sawan Province, Livestock Department officials also inspected a pig farm in Muang District, after all the pigs at the farm died suddenly. However, officials believed that all the pigs died from a bacterial infection that usually spreads during the change of seasons.

China Bans Thai Poultry Following H5N1 Bird Flu Outbreak

Editor: Sharon Li
5 Dec 2008 08:28:05 GMT

China has banned poultry imports and its related products from Thailand following a deadly H5N1 strain avian influenza outbreak there, the official Xinhua news agency reported, citing a statement from the Ministry of Agriculture.

The strain was discovered Oct. 27 in Thailand, Xinhua said. It is not immediately clear why China decided to ban poultry at this juncture.

The report didn't indicate how much poultry China imports from Thailand. The deadly H5N1 strain is blamed for hundreds of human deaths around the world and has devastated poultry stocks globally.

Health officials fear a mutating virus, which is already known to jump from birds to humans, that may cause a global pandemic.

Re: Thailand, H5N1 found in chickens

6 mutations (wrt. the genotype-Z index) from the little grebe 2004 were "undone"
while 12 new ones were generated.
So this doesn't look like a lab-error, a contamination with the little-grebe-virus
or another virus.
The sample could still have been stored and then intermixed with othe samples
and thus given a wrong collection-year

We also had this with 3 viruses from Vietnam 2005 that had the genes from
HK/1997 in almost unchanged form. A/duck/Vietnam/8/05(H5N1) ...

And the Hungary-Suffolk virus from 2007 that had only as many mutations
as similar viruses from >one year before.

H5N1 may in rare cases (<5&#37 survive unchanged in grebes or other animals
or in the environment without replicating, without mutating.

Maybe in immunodeficient animals in certain organs or organelles.
Maybe inside sandcorns or dust or bacteria or small holes protected
rom chemicals and radiation

no google-hits, no info where that st-351 sequence was from, no date (only 2008),
no location. Nor the circumstances nor any mentioning let alone speculation why
that virus was conserved for 4 years.
