What you'll see in our response is a system where we are constantly improving. We're constantly looking to eliminate risk—reduce risk, I should say. I can't say eliminate risk; there is no such thing as eliminating risk when it comes to COVID-19, but reduce risk as much as possible. And you see that in the fact that our system is always changing. We are always doing new things. You see that in day zero, day one testing. People are being tested as soon as they arrive, despite the fact that when we set it up, the day three and day 12 tests were regarded as the gold standard. We've improved that further by introducing the day one, day zero test.
