I've just done a quick and superficial survey on online newspapers in Latin America, Africa, New Zealand, and Australia. Maybe a more systematic and detailed search would turn up a different result, but my impression is that avian flu is a concern in only in east Asia, Australia, and North America.
Online newspapers in Mexico, Peru, Venezuela, Chile, and Argentina had nothing about avian flu, at least in pages accessible to non-subscribers. I found nothing in two major Brazilian news sites, nothing in two Portuguese sites, and nothing in various African sites. I couldn't find anything in New Zealand, and one or two stories in Australia. Perhaps it's different in Europe.
But it's striking to see that the sites I visited are all covering the Discovery mission, and the capture of the London bombers, and war news in Iraq. Avian flu and the outbreak of S suis II just don't seem to have registered outside the anglophone world. I would be delighted to be proven wrong.
