NIGERIA: The deadly bird flu virus has spread to poultry in northern Nigeria, the first time it has been detected in Africa, while China said yesterday that it was treating another victim of the disease.
The outbreak in Nigeria opens a fresh front in the battle against the virus, which has killed at least 88 people in seven countries since it re-emerged in late 2003. Iraq is also struggling to contain the disease.
Police cars and ambulances drove through the streets of the southern city of Amara yesterday urging residents to kill their birds to prevent its spread. So far, victims have contracted the disease through close contact with infected birds.
Experts stress cases of human infection are relatively few compared with the millions of birds that have contracted the disease. However, scientists fear that the H5N1 virus could mutate into a form that passes easily from person to person, sparking a human influenza pandemic.
"The outbreak in Kaduna state in northern Nigeria proves that no country is risk-free and that we are facing a serious international crisis," said Samuel Jutzi, a director of the UN's Food and Agriculture Organisation in Rome.
"If the situation in Nigeria gets out of control, it will have a devastating impact on the poultry population in the region, it will seriously damage the livelihoods of millions of people and it will increase the exposure of humans to the virus," Mr Jutzi added.
World Health Organisation regional adviser Adamou Yada noted there had not yet been any known cases among humans in Africa.
"In Africa we have so many diseases, so many priorities, if it spreads in Africa it will be a nightmare," Mr Yada said.
Bird flu is spreading westwards from Asia, where it is endemic in poultry across parts of the continent.
China has more poultry than anywhere else in the world and remains a key battleground in fighting the disease.
The latest bird flu patient brought the number of the country's confirmed cases in humans to 11, the Xinhua news agency said. Seven people have died from the virus in China.
The patient, a 26-year-old woman farmer from eastern China's Fujian province, was in a stable condition, Xinhua said, citing a report from the ministry of health.
Migratory birds have been blamed for the spread of the virus, but it is not clear how it reached Nigeria, with a poultry population of 140 million. Experts called for urgent action to halt further spread.
