摘　　要：The incidence of acute respiratory infections(ARinf),including SARS-CoV-2,in unvaccinated student rugby players during phases from complete lockdown during the COVID-19 pandemic to returning to competition is unknown.The aim of the study was to determine the incidence of ARinf(including SARS-CoV-2)during noncontact and contact phases during the COVID-19 pandemic to evaluate risk mitigation strategies.In this retrospective cohort study,319 top tier rugby players from 17 universities completed an online questionnaire.ARinf was reported during 4 phases over 14 months(April 2020–May 2021):phase 1(individual training),phase 2(non-contact team training),phase 3(contact team training)and phase 4(competition).Incidence(per 1000 player days)and Incidence Ratio(IR)for‘All ARinf’,and subgroups(SARS-CoV-2;‘Other ARinf’)are reported.Selected factors associated with ARinf were also explored.The incidence of‘All ARinf’(0.31)was significantly higher for SARS-CoV-2(0.23)vs.‘Other ARinf’(0.08)(p<0.01).The incidence of‘All ARinf’(IR¼3.6;p<0.01)and SARS-CoV-2(IR¼4.2;p<0.01)infection was significantly higher during contact(phases 3þ4)compared with non-contact(phases 1þ2).Demographics,level of sport,co-morbidities,allergies,influenza vaccination,injuries and lifestyle habits were not associated with ARinf incidence.In student rugby,contact phases are associated with a 3–4 times higher incidence of ARinf/SARS-CoV-2 compared to non-contact phases.Infection risk mitigation strategies in the contact sport setting are important.Data from this study serve as a platform to which future research on incidence of ARinf in athletes within contact team sports,can be compared.
