I do not understand why staff at all isolation facilities were not required to wear masks and other personal protective equipment (PPE) until last Wednesday. How can that be? Staff at isolation facilities were not required to wear PPE until last Wednesday. The argument is that returnees stay in their room and, when they come out of the room, they're required to wear a mask, and staff only have to mask up if they're more than two metres from those returning people. That's a hard problem. It's a hard problem in a hotel to stay two metres from someone coming and going, let alone talking about the fomite, the intangible objects that we believe some of the virus can live on. That's a hard problem. It actually would have been easier to say, "Look, we're going to require all of you staff—to keep you safe, we're going to require all of you—to at least wear a mask and other PPE." Eventually, on Wednesday, the Government got to that position.
