Fig. 2From: Resuming Training in High-Level Athletes After Mild COVID-19 Infection: A Multicenter Prospective Study (ASCCOVID-19)Occurrence of positive SARS-CoV-2 diagnosis during F-NRL season (RT-PCR and serologies). The F-NRL protocol involved twice-weekly SARS-CoV-2 RT-PCR testing (D614G variant). COVID(+) diagnosis was based on positive serology or a positive SARS-CoV-2 RT-PCR. 192/206 COVID(+)incident cases were diagnosed by positive RT-PCR and 14 by positive serology (without previous positive RT-PCR). SARS-CoV-2 seroconversion (IgM and/or IgG) occurred in 155 (80.7%) of the 192 players diagnosed by RT-PCR, while 25 (13%) did not show detectable anti-SARS-CoV-2 antibodies during the follow-up periodBack to article page
