Bird flu has spread from poultry and infected humans in five countries. The World Health Organisation recognises 79 deaths from among the 148 cases that have been recorded globally so far.
Vietnam
Vietnam is the country worst affected by bird flu, with 42 deaths and 93 cases. Most deaths happened between late 2003 and mid-2005.
Nearly 50m poultry have been culled in attempts to limit the spread of the disease. On January 5 2006, the government said it had completed its programme of vaccinating 150m poultry around the country.

Thailand
The country suffered at the beginning of the current outbreak, with 22 cases and 14 deaths since December 2003.
After a lull lasting nearly a year, authorities confirmed on November 1 2005 that three people had been infected during the previous month. This coincided with a recurrence of bird flu among poultry in six provinces.
The latest victim was a five-year-old boy whose death was confirmed on December 9 2005. Officials hope to start human trials of an H5N1 vaccine in March, and the Thai government has announced it will start producing a generic version of the anti-viral drug Tamiflu.

Indonesia
Seventeen people have been infected in recent months. Twelve of them have died, the latest a 29-year-old midwife who worked in a Jakarta hospital.
The authorities have imposed "extraordinary" measures, including the power to force people suspected of having bird flu into hospital. Most Indonesian households keep chickens or caged birds as pets.

China
Five of the eight people to have been infected in China have died. There have been confirmed outbreaks in six provinces and regions - Hunan, Anhui, Guangxi, Liaoning, Jiangxi and Fujian.
On November 15 2005, the government announced plans to vaccinate all 14bn of China's farm birds after more than a dozen confirmed outbreaks. Millions of birds had already been culled before the programme was announced.
In August 2004, the authorities revealed that the H5N1 virus had been found in pigs, but denied claims they had kept an outbreak of bid flu secret for more than a year.
British flu experts visited China in October 2005 to find out how the Chinese were responding to the threat. During the Sars outbreak in Asia, there was concern that China had failed to reveal the full extent of the crisis.
There have also been reports that China's use of the anti-viral drug amantadine in animals may have resulted in the H5N1 virus becoming resistant to treatment in the far east.

Turkey
Bird flu in humans was confirmed on January 5 2006 when a brother and sister died from H5N1 virus in the eastern town of Dogubayazit, close to Turkey's border with Iran. A week later, a third sibling died, followed by a 12-year-old girl from the same town and a 14-year-old girl who died on January 15.
The WHO has confirmed, subject to additional tests, 20 cases of bird flu in 12 of Turkey's 81 provinces. Outbreaks in another 19 provinces are under investigation.
On October 10 2005, the EU banned the import of live birds, poultry meat and feathers from Turkey after 1,870 birds died of avian flu in the country. A two-mile quarantine zone was imposed around the affected area, and thousands of turkeys were culled.

Cambodia
All four people confirmed to have contracted bird flu in Cambodia have subsequently died. US health officials have expressed concern about the country's surveillance and containment capacities should a mutation take place.
The US has offered $2m (£1.14m) to improve the country's response systems.

Bird flu has been confirmed in poultry in the following countries:
Japan
Among the first countries to be affected by the current outbreak of bird flu. In March 2004, a poultry firm boss and his wife committed suicide after apparently covering up an outbreak.

Romania
The H5N1 strain was confirmed in the country on October 15 2005, with the authorities placing an exclusion zone around the villages in the Danube delta where bird flu had been found.
The Guardian' s Mark Honigsbaum witnessed police apparently confused about which vehicles should be sprayed. There were also local reports that dead birds had been washed up on the shores three months before officials acted.

Greece
A suspected outbreak of bird flu was reported at a turkey farm on the Aegean island of Oinouses, near the coast of Turkey, on October 17 2005. However, the European commission said on October 31 that a second series of tests had proved negative.
UK
On October 21 2005, authorities confirmed that a parrot from Surinam had died in quarantine in Essex after being infected with bird flu, which was later confirmed as the H5N1 strain. Government scientists said it was likely the bird had caught the disease from Taiwanese birds in quarantine. Because the flu was confined to quarantine, the government says Britain retains its disease-free status.
Government officials are spending £200m to buy 14.6m doses of Tamiflu. The government is also purchasing 2m treatments of bird flu vaccine to treat key workers.
Birdwatchers have been enlisted to help identify any arrival of bird flu quickly. The Department of Health has published its contingency plan, as has Defra, the rural affairs and agriculture department.
In December 2005, a House of Lords committee report said the government could do more to prepare the UK for a pandemic, and warned of food shortages and panic buying if the disease struck.
Were bird flu to arrive, the initial reaction would include the setting up of exclusion zones around infected areas, the culling of flocks and the vaccination of key workers.

Germany
On October 25 2005, dead wild geese found in western Germany were confirmed to have tested positive for bird flu, although analysis of the specific strain continues.
Officials had already tightened border controls, and the authorities in Bavaria have banned poultry markets.
Germany is one of the few countries stockpiling large quantities of Relenza as an alternative to Tamiflu. Its order, for 1.7m units, reportedly exceeded the global sales of the drug for the past four years.

Canada
A surveillance programme of wildfowl carried out in seven provinces in August and September 2005 found the H5 strain in 28 Quebec birds and five Manitoba birds.
The Canadian Food Inspection Agency said the virus had been present in wild birds for some time and was not the H5N1 variety.
Elsewhere
There also have been confirmed cases amongst poultry in Ukraine, Croatia, Taiwan, Laos, Malaysia, South Korea, Russia, Kazakhstan and Mongolia.
EU
On October 25 2005, the EU announced a month-long ban, since extended, on the import of wild birds after the H5N1 strain was discovered among birds held in British quarantine.
Officials had decided already to restrict keeping poultry outdoors in areas at particular risk of avian influenza, such as those near marshland. Member states are responsible for defining the risk areas.
The standing committee also agreed on an immediate, EU-wide ban on the collection of birds at markets, shows, exhibitions and cultural events unless specifically authorised by authorities.
Officials have approved additional bio-security measures including, if deemed appropriate, vaccination to protect birds kept in zoos.
On November 7 2005, the EU announced it would give €30m (£20.2m) to help Asian countries tackle the disease. An additional €50m was pledged on January 13 2006.

US
Although there have been no cases of the current bird flu outbreak in the US, the president, George Bush, says he has considered using the military to maintain control should the strain appear.
Grounding airlines could be another measure, Mr Bush - who took a book about the 1918 Spanish flu pandemic on holiday with him recently - indicated.
In September 2005, the Senate voted to spend $3.9bn in bird flu funds, largely to build domestic stockpiles of antiviral drugs and vaccines. By mid-October 2005, the US had a stockpile of around 2.3m courses of Tamiflu, with more on order.
It also has around 83,000 courses of zanamivir (Relenza), another antiviral, which could be used to treat sufferers.
Officials at San Francisco airport, a major gateway to the US from Asia, have been told to look out for signs of avian flu among travellers.

Singapore
With bird flu outbreaks confirmed in neighbouring countries, Singapore banned people from keeping live chickens on the island of Pulau Ubin in June 2005. The government has also told people not to visit poultry farms.
Australia
Warnings issued by the government include advice to wash eggs before cracking them open, and to clean hands afterwards because the virus can be transmitted through dirt and poultry faeces.

The Netherlands
In 2003, 28m birds were slaughtered in the Netherlands after a less deadly strain, H7N7, infected birds and 89 people. One vet subsequently died. In August 2005, the government ordered all poultry to be kept indoors. Because the domestic free range chicken industry is small, this caused relatively little disruption.
Italy
According to the agricultural association, Una, consumption of chicken has gone down by 30% since the crisis began. The real figure is thought to be higher, with consumption in some areas down by 70% and egg sales also hit.
National and regional authorities have ordered 12m vaccine doses, covering 20% of the population.
France
The French health minister, Xavier Bertrand, said on January 11 this year that the country will have spent $844m (£477m) between 2004 and 2006 on preparing for a flu pandemic.
Provisions include 14m doses of antiviral drugs, 50m face masks for hospitals (with 150m more on the way) and 40m doses of any future vaccine. Airport controls have been stepped up, and a good practice guide distributed to farmers, who have been told to keep birds indoors as much as possible.
By January, two-thirds of poultry had been ordered to be kept indoors. The agriculture minister, Dominique Bussereau, said poultry sales had dropped by 20% in the previous quarter.
