The national bird flu reference laboratory confirmed on Jan. 27 that the death of ducks in south China's Guangxi Zhuang Autonomous Region was caused by the bird flu virus, but no infections in human beings have been found.

Following reports of ducks dying on a duck farm in Dingdang Town, Long'an County on Friday, the local government slaughtered 14,000 poultry within a three kilometer radius of the duck farm, and vaccinated all poultry within five kilometers of the duck farm.

After testing of samples sent in by the local government the lab confirmed that the deaths were caused by the deadly H5N1 strain of the bird flu virus.

The local government has closed off the area in accordance with China's Law on Animal Epidemic Prevention.

A separate report on Monday said deaths were reported on a chicken farm in Wuxue city in central Hubei Province and ducks were also said to have died on a farm in Wugang city in neighboring Hunan Province. Local veterinary departments initially diagnosed the cause of the deaths as suspect deadly H5N1 strain of the bird flu virus. Local governments have slaughtered and vaccinated birds in the area, and sent samples to relevant authorities.

No people have been infected so far and the epidemic is under control, the government sources said.

Jia Youling, chief expert on farming of the Ministry of Agriculture, said on Tuesday that prevention work against bird flu dated back over 100 years and many nations had accumulated valuable experience, which proved the feasibility of preventing a serious outbreak.

The disease can be controlled if effective measures are taken to block the affected area, kill all the infected poultry and sanitize affected areas, said Jia.

Officials from the Ministry of Agriculture and the Ministry of Health have informed the UN Food and Agricultural Organization and the World Health Organization of the cases, and said exchange and cooperation in bird flu prevention and control was welcome.

The Ministry of Agriculture issued emergency directives on Jan.20 requiring veterinary and quarantine units to report the bird flu situation to higher departments every day. It was the second emergency notice the ministry had promulgated following the outbreak of bird flu in Vietnam, the Republic of Korea (ROK) and Japan early this month.

The notice in particular asked local governments to step up the quarantine of poultry and the monitoring of the H5N1 strain of bird flu. It also asked local governments to set up emergency teams and store materials for emergency use.

"If cases of bird flu are spotted, all poultry within three kilometers of the site must be slaughtered and all poultry within five kilometers of the polluted region must be vaccinated immediately," said the notice.

Also on Jan. 20, six ministries and state administrations jointly issued a ban on live poultry and product imports from regions hit by the H5N1 strain of bird flu.

Since the beginning of January, government departments at all levels have been maintaining high alert to guarantee the safety offood and people's health during the one-week traditional Chinese Lunar New Year holiday, which began Jan. 22.

The deadly virus - highly contagious among chickens - is believed to spread to humans through contact with infected birds, but there have been no reports of the disease spreading from person to person.

Chief agricultural expert explains bird flu

Following is a brief introduction to bird flu by Jia Youling, chief expert on farming of the Ministry of Agriculture.

What is bird flu?

Jia: Bird flu is an infectious disease caused by a form of influenza virus. The disease is mainly found in fowl such as chickens, ducks, geese and pigeons.

How is the disease confirmed?

Jia: The process of confirmation will usually follow four steps. First, experts diagnose dead birds on site and through epidemiological methods make an initial judgment if the death is caused by suspected strain of bird flu virus. Secondly, serological methods may be applied for a detailed checkup. Then, the national bird flu reference lab works out final confirmation after further examination. In the end, the Ministry of Agriculture will officially acknowledge the disease based on report of the lab.

Can the disease be prevented and controlled?

Jia: Prevention work against bird flu dates back over 100 years and many nations have accumulated valuable experience, which proves the feasibility of preventing a serious outbreak.

The disease can be controlled if effective measures are taken to block the affected area, kill all the infected poultry and sanitize affected areas.

What measures did the government take after the case in Guangxi was reported?

Jia: As soon as the disease was reported, local governments immediately blocked the affected site, slaughtered all the poultry within three kilometers radius of the duck farm in Dingdang town of Long'an county, Guangxi Zhuang Autonomous Region and vaccinated all the poultry within five kilometers radius of the site. All these were conducted in line with China's Law on Animal Epidemic Prevention and regulations of the Ministry of Agriculture.

Under the direction of the State Council, the Ministry will make painstaking efforts to monitor the situation and prevent further spread of the disease. The Ministry is willing to strengthen exchange and cooperation with relevant world organizations. The Ministry has also made appropriate arrangements for prevention work in other areas.
