There are some quite tricky challenges facing everybody working in Crimea and I shall be engaging with various government people.

If there is delay in getting culling teams out, delay in any part of the chain, even weeks, that could have great implications for the virus to spread.

The flu-casters would draw out the maps and keep people engaged at regular intervals ... beaming it from the WHO bunker.

There is a chance that we could have at least as many dying from communicable diseases as we've had dying from the tsunami.

The virus is moving quite substantially into new locations. My attention is pretty much equally divided between Europe, the southern Balkans and Black Sea area, Africa and south Asia.

We are watching very closely to see how the disease associated with bird flu, when it hits humans, is evolving.

This outbreak is moving ahead of efforts to control it.
