There is still a window of opportunity for substantially reducing the risk of a human pandemic evolving from H5N1 by controlling the virus at its source, in animals.
Everything has to be done to find out exactly where the virus came from, since it would be a big surprise to find it in South America.
The highly pathogenic avian influenza virus poses a very serious threat to animal health in West Africa. If a poultry epidemic should develop beyond the boundaries of Nigeria the effects would be disastrous for the livelihoods and the food security of millions of people.
The priority to prevent the pandemic still stands on Asia, but besides that, if the virus is coming in Africa, yes, it's a very big worry for us.
