>> do you agree with the updated guidance? do you think testing needs to be included to help bring down the number of cases? >> i think the guidance to reduce isolation to five days, the principle of it is sound, and it's very important that we attempt to reduce isolation as much as possible. many people don't actually get detected using a pcr test until after they've been infectious. so we need to keep isolation as minimal as possible, but we also go through all this effort to find positive and infectious people, and when we do find those individuals, we should make sure to do everything we can to ensure that they do not go on and unintentionally infect their cleeks or their family. that's where just using inserting a rapid test into the guidance to say use a rapid test at day five, and if you're still positive, do not leave isolation. if you're negative, then follow the rest of the guidance which is wear a mask and you can leave
