We're undoubtedly very concerned about many aspects of this case. The case clearly shows the limits that we face, in part because of privacy legislation and the fact that the issue is before the courts.
In addition, we must note that we have limited knowledge of what happened and the nature of the risks faced by our employees.
We are perfectly happy to answer questions in this regard, notwithstanding the limits.
I can tell you that we have learned as we have proceeded. We have worked with the Cuban authorities to the maximum degree possible. We have worked with our American colleagues to learn as much as we can. And we have applied more measures to safeguard our employees in Havana, including restricting the footprint in Havana to respond to continuing concerns and incidents there. We will continue to apply that standard of care.
We don't always know where the threats are going to come from. In this particular case, it is especially troubling that we don't know precisely what the source of the problem is. We have provided the appropriate diagnostic testing and care. We continue to meet with the staff concerned. Those cases represent a wide variety of circumstances and of reactions within those families, our staff and their dependants, so there is no single pattern that points very clearly to a problem and/or the nature of the problem.
As I said, we have learned as we've gone; we know more than we did in the early days. But this is an extremely troubling situation and we are open to whatever technical advice we are receiving from medical personnel and from our colleagues, as well as from other agencies we're working with, such as the RCMP and so on.
