High prevalence of SARS-CoV-2 infection in repatriation flights to Greece from three European countries

Abstract
Passengers on repatriation flights to Greece from the UK, Spain and Turkey were screened with oropharyngeal swabs on arrival for SARS-CoV-2 infection. Despite almost all passengers being asymptomatic, many tested positive (3.6% from UK, 6.3% from Spain and 6.3% from Turkey), indicating widespread transmission of SARS-CoV-2 in these countries.
