The Danube Delta, shared by Romania and Ukraine, is one of the majortransit destinations for migrating birds, which are believed to bespreading the bird-flu virus. Most human bird-flu infections have beentraced to contact with birds. But scientists say the possibility existsthat the virus will mutate into a form that can be spread from human tohuman, triggering a pandemic that could kill millions.However, Maria Cheng, a spokeswoman for the World Health Organization(WHO), the United Nations health agency, told RFE/RL that a cleardistinction should be made between the current outbreaks and a possiblemutation that could affect humans on a broad scale."I think what most people are worried about is the spread of flu aroundthe world in a pandemic, but that's not the situation we have here,"Cheng said. "These outbreaks in Europe are outbreaks of an animaldisease. Avian influenza H5N1 still very rarely affects humans, so itis not a risk for the public at large. But we are worried about it,because it does have potential to change into a strain that couldultimately cause a pandemic."Health officials, however, are urging the international community notto waste any time in getting prepared. David Nabarro, the UN's recentlyappointed coordinator for bird and human influenza, has warned that theworld needs six months to a year to prepare for a possible pandemic.U.S. Health Secretary Mike Leavitt, in Vietnam yesterday, noted thatthe international community is racing to upgrade preparations. "Itwould be my assessment that no nation is adequately prepared for apandemic avian flu," he said. "I believe that most nations areimproving, and preparations are increasing."The WHO has said that further outbreaks of avian disease are expectedin different countries. But the WHO cautioned that a mutated humanstrain is more likely to emerge in Asia than in other parts of theworld. "It could theoretically happen anywhere," WHO spokeswoman Chengsaid. "But because we're seeing the most outbreaks and we've identifiedhuman cases in Asia, we still believe that Asia is the focus of theavian-influenza outbreak. So, just by the fact that there's much morevirus in Asia and that we've seen it infect people there, from thatpoint of view it is more likely that we would see it happen in Asiajust because of the amount of virus that it's there."The UN's Nabarro said the international community should help financeemergency plans to help poor Asian countries fight a potentialpandemic.See also:EU Prepares For Pandemic As Bird Flu Reaches GreeceBird Flu FAQ
