South China province was on high alert and surveillance on poultry and migrant birds has been tightened after a woman died of bird flu in Beijing.

A deadly bird flu virus may have spread to another site in Britain, with suspicious deaths at a turkey farm in Suffolk, the farm ministry said.

An international team of researchers says it has discovered what makes the bird flu virus so deadly. It appears the disease affects a wide range of organs other than the lungs in adults and is capable of killing the fetus of pregnant women.

Researchers at the Institute of Bioengineering and Nanotechnology (IBN), Institute of Molecular and Cell Biology (IMCB) and Genome Institute of Singapore (GIS) have successfully developed a miniaturized device that can be used to detect the highly pathogenic avian flu (H5N1) virus.

An outbreak of H5N1 bird flu occurred among ducks in southern China, according to China's Agriculture Ministry, Hong Kong's health secretary said Monday.

More than 200,000 ducks would be slaughtered at two farms in Bavaria to avoid bird flu spreading. The head of Bavaria's state office for health and food safety, Volker Hingst, said the slaughter was "a purely precautionary measure," taken after "laboratory indications of H5N1" were found. The birds were not visibly sick, he said.

Researchers say studies do not confirm whether wild birds are carriers of the H5N1 bird flu virus. VOA's Luis Ramirez reports from Bangkok, where experts are gathering this week to figure out better ways to track how the disease is spreading.

In the first systematic, statistical analysis of its kind, infectious-disease-modeling experts at Fred Hutchinson Cancer Research Center confirm that the avian influenza A (H5N1) virus in 2006 spread between a small number of people within a family in Indonesia.

The World Health Organization (WHO) has reinforced that Tamiflu (oseltamivir) is the primary recommended antiviral of choice in managing patients infected with H5N1 in updated guidance published on the WHO website today.

Ukraine has almost completed clinical trials for a bird flu vaccine, the head of the Ukrainian State Veterinarian Department said Thursday. Since 2003, when bird flu first hit countries in Asia, international experts feared the virus could mutate into a form that spread easily among people, sparking a global pandemic.

The United Nations is taking steps to promote the application of space technology to help Asian-Pacific countries fight bird flu, drawing on its potential as part of an integrated early-warning system to track the virus’s path in a region that has suffered by far the largest share of both human and avian infections in the world.

As workers began slaughtering 150,000 chickens near a farm where a deadly bird flu virus was found, health in India's remote northeast went house-to-house searching for sick people Thursday.
