How extensive the problem is in India is still not known.

We encouraged the countries to increase surveillance. But I'm not a policeman. What I can do is to ask governments to be more vigilant.

We don't have a spread of the virus, what we have is the introduction of the virus into countries of the European Union. The difference is that it's human activities, through commerce, through the market place, through the way we raise our poultry that we get disease spread. The fact that in Europe, in many countries, it's been picked up in migratory birds, is very, very relevant, it means that the European authorities -- Italy, Greece, Germany, Denmark, Austria -- are monitoring, doing active surveillance in the wild bird population.

Markets go throughout Kurdistan and occur on mules and donkeys who cross borders here and there. And chickens are small. It's quite difficult to control.

They cordoned off the area and increased a surveillance zone to about 10 kilometers. Because some of the poultry were inside the 10-kilometer area, they were sequestered -- no movement in, no movement out. There was rapid sending of the samples [for testing], confirmatory diagnosis, quick action on part of the Ministry of Agriculture to hold a press conference and take measures at the local level, and good coordination between the central and provincial governments.

It's like looking at bread crumbs, but you don't see the whole loaf.
