Returning briefly to a couple of points made in the debate about the specific set of circumstances, the problem we have at the moment is identifying what is case zero. Mr Bishop alluded to this. So, yes, there is somebody who works in a laundry that launders material that comes off flights. People such as myself will go, "Well, there you go." We will hear from Dr Verrall later in the debate, and I'm sure she will be able to work through some of the concerns and issues that people have raised about things like fomite transmission. While that remains a possibility and an investigating point for us, we do have to accept that it is people-to-people contact that is the primary way in which this is transmitted, and that, Mr Bishop, is why there is such a focus in the advice we have had on air-side. Because even if a person is a baggage handler, they are in the air-side, they are in the space in which there are people who are coming in and transiting and so forth through the country. That is not to dismiss the question of fomite transmission, and we've spent a lot of time talking about it and it is being investigated. But I just make the point that the public health advice remains that it is people-to-people transmission that is the most likely and the most risky situation. Hence why those rules have been made the way they are. But as part of our continuous improvement process, we're now looking at whether or not a facility such as a laundry does need to be looked at. So we constantly look to evolve what we're doing.
