AHPPC notes that due to the large number of locations, there is limited usefulness in listing exposure locations in high field numbers. AHPPC recommends maintaining QR code check-in at high-risk locations as it allows for quick detection of high-risk infection events and locations. AHPPC recommends using QR code check-in in areas where vulnerable people have a high risk of infection (such as hospitals and RACF), large numbers of immunized individuals or settings where outbreaks can cause social and economic disruption (such as serious industry) where multiple positive person isolation Can cause significant disruption of essential services). AHPPC recommends reviewing the utility of QR code check-in in low-risk areas, and with most of these settings, secondary yields are offered.
