目的研究橄榄球联赛中SARS冠状病毒2（SARS-CoV-2）阳性运动员与其他运动员之间的相互作用，确定比赛中SARS冠状病毒2（SARS-CoV-2）传播的风险。方法对4场中超联赛中SARS-CoV-2阳性运动员参加的比赛进行分析。玩家被确定为风险增加的接触者，并通过视频片段和全球定位系统（GPS）数据分析了玩家的互动和接近程度。主要结果是在比赛后14天内，在风险增加的接触者和参加比赛的其他球员中出现新的SARS-CoV-2阳性病例。结果在136名运动员中，SARS-CoV-2阳性运动员8名，高危接触者28名，其他运动员100名。增加风险的接触和其他球员分别参与了11.4 +/- 9.0（最大32）和4.0 +/- 5.2（最大23）铲球。从GPS数据来看，增加风险接触者和其他玩家在10.4 +/- 18.0（最大88）和12.5 +/- 20.7（最大121）的情况下与SARS-CoV-2阳性玩家相距2米以内，分别为65.7 +/- 137.7（最大689）和89.5 +/- 169.4（最大1003）s。在比赛结束后的14天内，一名风险增加的接触者和五名球员返回了阳性SARS-CoV-2逆转录酶PCR（RT-PCR）测试，27名风险增加的接触者和95名其他参与者返回了阴性SARS-CoV-2 RT-PCR测试。阳性病例最有可能追溯到社交互动、汽车共享和更广泛的社区传播，而与比赛中的传播无关。结论尽管有铲球参与和与SARS-CoV-2阳性运动员的近距离互动，但比赛中SARS-CoV-2传播尚未得到证实。虽然需要更大的数据集，但这些发现表明橄榄球的病毒传播风险低于先前的预测。
Objectives To examine the interactions between SARS-CoV-2 positive players and other players during rugby league matches and determine within-match SARS-CoV-2 transmission risk. Methods Four Super League matches in which SARS-CoV-2 positive players were subsequently found to have participated were analysed. Players were identified as increased-risk contacts, and player interactions and proximities were analysed by video footage and global positioning system (GPS) data. The primary outcome was new positive cases of SARS-CoV-2 within 14 days of the match in increased-risk contacts and other players participating in the matches. Results Out of 136 total players, there were 8 SARS-CoV-2 positive players, 28 players identified as increased-risk contacts and 100 other players in the matches. Increased-risk contacts and other players were involved in 11.4 +/- 9.0 (maximum 32) and 4.0 +/- 5.2 (maximum 23) tackles, respectively. From GPS data, increased-risk contacts and other players were within 2 m of SARS-CoV-2 positive players on 10.4 +/- 18.0 (maximum 88) and 12.5 +/- 20.7 (maximum 121) occasions, totalling 65.7 +/- 137.7 (maximum 689) and 89.5 +/- 169.4 (maximum 1003) s, respectively. Within 14 days of the match, one increased-risk contact and five players returned positive SARS-CoV-2 reverse transcriptase PCR (RT-PCR) tests, and 27 increased-risk contacts and 95 other participants returned negative SARS-CoV-2 RT-PCR tests. Positive cases were most likely traced to social interactions, car sharing and wider community transmission and not linked to in-match transmission. Conclusion Despite tackle involvements and close proximity interactions with SARS-CoV-2 positive players, in-match SARS-CoV-2 transmission was not confirmed. While larger datasets are needed, these findings suggest rugby presents a lower risk of viral transmission than previously predicted.
