We evaluated the seroprevalence of SARS-CoV-2 and risk factors among 4,987 oligo/asymptomatic HCW. The seroprevalence was 14% and factors associated with being infected with SARS-CoV-2 were lower educational level(aOR of 1.93;95%CI1.03-3.60), using public transport to work (aOR of 1.65;95%CI 1.07-2.62), and working in cleaning or security (aOR of 10.1;95%CI 3.40-26.9).
