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.
