Real-world utilisation of SARS-CoV-2 rapid antigen testing to enable face-to-face learning in Australian schools, an ecological study.

Objective: The objective of this study was to describe the use of SARS-CoV-2 rapid antigen testing of COVID-19 contacts in New South Wales schools to determine return to in-person school attendance instead of home quarantine, between 6 November and 21 December 2021.

Methods: COVID-19 school contacts were required to quarantine for two weeks postexposure to the case. Students who opted into daily rapid antigen testing logged their results in a database, prior to school attendance, and obtained SARS-CoV-2 nucleic amplification acid testing on day 12-16.
