We've been working directly with WHO. Dr. Theresa Tam, who is the deputy chief public health officer, is in Geneva as we speak discussing what's going to happen from a scientific perspective, so our contributions at this point in time to WHO in particular have been expertise, etc.
We're working closely with PAHO, and as I alluded to earlier, we're planning on assisting CARPHA in the Caribbean as a potential area with some laboratory assistance. That will happen in the next little while.
At this point in time it's typically expertise. Matt may be sending some folks to CARPHA, for example.
