I'll start and then I'll turn it over to you, Karen.
First of all and importantly, the health and safety of our athletes and coaches is, for all of our mission team members, always our first priority whenever we're preparing to go for games.
We're in the fortunate position of having great leadership within the medical community and attached to our Olympic mission. Dr. Bob McCormack has been involved with us for as long as I've been involved over the last six years. As our chief medical officer, he provides great continuity for the Olympic team, games over games, and has many relationships around the world at the highest levels, which allow him not only to monitor the circumstances around health and safety but also to be an active part of the conversations.
We have great comfort in the information we're getting both from the Rio organizing committee and first-hand from our chief medical officer, and in the steps we've taken to mitigate those circumstances.
Of course, we've seen headlines in the last couple of days that I think would provide possible cause for concern to almost any person, but the information we get is that it's well under control, and certainly the recent statements from the World Health Organization would indicate that they feel the same, despite some of what has been said by the broader medical community internationally.
As most of you will probably be aware, the WHO has convened a meeting later in June in Geneva to discuss it further, but, again, the comfort and assurances we have, as provided by our medical team and by the international authorities, give us good confidence.
