RESUMO
OBJECTIVES: The risk of viral transmission associated with contact sports such as football (soccer) during the COVID-19 pandemic is unknown. The aim of this study was to describe the infective and immune status of professional football players, team staff and league officials over a truncated football season resumed at the height of the COVID-19 pandemic in a country with high infection rates and to investigate the clinical symptoms related to COVID-19 infection in professional football players. METHODS: Prospective cohort study of 1337 football players, staff and officials during a truncated football season (9 weeks) with a tailored infection control programme based on preventive measures and regular SARS-CoV-2 PCR swab testing (every 3-5 days) combined with serology testing for immunity (every 4 weeks). Clinical symptoms in positive participants were recorded using a 26-item, Likert-Scale-based scoring system. RESULTS: During the study period, 85 subjects returned positive (cycle threshold (cT) ≤30) or reactive (30Assuntos

RESUMO
Background: We assessed SARS-CoV-2 contamination of random surfaces in football training facilities in an environment with a high prevalence of infections.Methods: In six clubs of the Qatar Stars League, surfaces of random locations (high-touch areas, ventilation systems, toilets, cleaning tools, freezers, pantries) in routinely cleaned training facilities, locker rooms, medical and administrative areas were swabbed for SARS-CoV-2. The swabs were screened for the presence of viral RNA using a SARS-CoV-2 qPCR Probe Assay.Results: None of the 103 swabs reached a cycle threshold (cT) value ≤30 (strong viral presence, suggestive of potential surface transmission). Four samples showed cT values >30 and <35 (low quantity of virus) and 16 swabs returned a cT value ≥35 and <40 (inactive virus remnants). The remaining 83 samples were negative (cT value ≥40). Most samples with viral or viral remnant presence originated from high-touch areas.Conclusion: We did not find evidence for potential surface transmission in football club facilities when routine cleaning procedures are in place despite the presence of infected subjects.
