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

This outbreak is moving ahead of efforts to control it.

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.

Detecting and culling infected birds is still the key, and for that we have to compensate the owners of chicken whose flocks are killed. And we have to limit interaction between humans and birds, which is a huge challenge within an environment where people are used to living very close to their chickens.

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.

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