Reducing onward spread of COVID-19 from imported cases: quarantine and ‘stay at home’ measures for travellers and returning residents to Singapore

Abstract
Singapore imposed a 14-day ‘Stay Home Notice’ (SHN) on travellers and returning residents to reduce secondary transmission from imported cases of COVID-19. In this article, we describe the processes and enforcement of SHN, and explore the issues faced by individuals under such quarantine, and the steps taken to address them.
