Abstract
Hundred and ninety-six travellers with negative-COVID-19-tests prior to departure tested positive, on arrival at Madrid (April/June 2021), from a total of 45 211 travellers tested (0.43%). Viral loads (Ct: 20.3) were higher compared to the general population (Ct: 27.09). Our data reveal weaknesses in pre-departure testing and alert about high-viral-load-SARS-CoV-2 carriers in intercontinental flights.Keywords
