I would like to say that the global polio eradication initiative is a great partnership with a number of players. WHO and UNICEF are key partners. The Gates Foundation is a strong contributor. It has been able to rally many people together. The Rotarians were a great example. They were very successful in Canada, but they are also very successful internationally.
One of their concerns is people are forgetting what polio looked like. It's easy to forget it. One of the issues now is often the safety of polio workers. We have seen cases in some places in Nigeria or Pakistan. We're now trying to tackle the most difficult areas.
The last thing I want to say is that a lot of the polio workers, and the network that had been created for this, have been extremely useful for Ebola to make sure the health system is also able to address issues like this. We've seen in West Africa how they have been able to use that network.
