It was the same in Asia. It mainly occurred in family clusters of small size, and mainly in children.

As long as we're dealing only with migratory birds being found here and there, I don't think it's a big deal, frankly. The big issue is if we start to have domestic poultry infected. Then it would start to be a problem ... a higher risk for transmission to humans.

I have to say that the (Turkish) minister of health is completely open to these issues of opportunity . . . to learn more about H5N1 in humans.

The two brothers are a very interesting finding that may for the first time give us a chance to monitor the human response to the disease.

When we have a child infected we are giving the virus more chance to adapt to human beings, and giving it this chance could help create conditions for the emergence of a new virus.

Compared to the numbers in Asia, we do not have too many deaths at the moment.
