Pre-departure PCR testing of travellers for SARS-CoV-2 was an effective tool in limiting transmission in Greenland during the early phases of the COVID-19 pandemic

BACKGROUND: During the early part of the COVID-19 pandemic, travel restrictions were implemented in Greenland to contain SARS-CoV-2 transmission. Despite their widespread use, empirical evidence supporting the effectiveness of travel restrictions is scarce. Greenland was in a unique position to maintain pre-departure testing among travellers, and we aimed to describe the effectiveness of pre-departure testing to inform the implementation of travel restrictions in future outbreaks. METHODS: Our analysis included SARS-Cov-2 PCR test results from travellers, including children, arriving in Greenland from Denmark between June 15, 2020, and January 26, 2022. Additionally, we identified positive tests performed within 14 days post-arrival to Greenland in this population. We estimated the sensitivity of pre-departure screening by dividing the number of positive cases identified …
