I would only add that of course the organizing committee takes the first responsibility. All of us have heard first-hand about some of the mitigating steps that the organizing committee has taken on the ground. There's been lots of spraying and work done around the venues and so on that they're managing.
Otherwise our instructions quite literally to our athletes, coaches, and all of our mission team members is generally preventive in its orientation. We have many opportunities to intersect with them in that regard. We hold seminars for our athletes and coaches. In recent weeks we had our team orientation preparation seminar, which involved most of our mission team members. In these we have the chance to brief them on all matters of games operations, including security, health, and safety. We have team orientation sessions that we undertake before the team goes, and then again orientation sessions once they arrive in Rio.
All of those are opportunities to give them quite literal instruction about preventive measures. Then, of course, we lean on the World Health Organization and the other bodies that are advising Brazil on preventive measures for those who might be prepared to take families or for those who attend and are perhaps preparing for families after Rio. They are quite direct and literal instructions around family planning, which we consider, of course, and advise our athletes and mission team members on.
