从医学角度评估 COVID-19 大流行期间德甲联赛（足球（英式足球））的重启。参与者是来自德国两个最高联赛的男性职业足球运动员以及与他们密切合作的官员。我们的报告涵盖了 9 周（2020 年 5 月至 7 月）的 9 个比赛日。进行了每日症状监测、每周两次 SARS-CoV-2 RNA PCR 检测以及抗体检测（两次——2020 年 5 月阶段初期和最后一场比赛当周）。目标变量是：(1) 出现典型的 COVID-19 症状，(2) PCR 结果呈阳性，以及 (3) 针对 SARS-CoV-2 的 IgG 血清转化。所有检测到的血清转化均通过中和试验控制。据报道，一名球员出现可疑症状；立即进行的额外 PCR 检测以及所有后续诊断和抗体检测均证明冠状病毒呈阴性。在 1702 名定期检测人员（1079 名球员、623 名官员）中，8 名球员和 4 名官员在球队训练开始前的第一轮 PCR 检测中检测呈阳性，2 名球员在第三轮检测中呈阳性。在本赛季剩余时间里没有出现进一步的积极结果。 694名球员和291名官员提供了两份血清样本进行抗体检测。九名球员从阴性/边缘转为阳性（无症状）；两名最初检测呈阳性的球员在赛季末检测呈阴性。整个赛季有 22 名球员保持血清阳性。中和试验未证实任何血清转化。在新冠肺炎 (COVID-19) 疫情期间，专业足球训练和比赛可以安全进行。这需要严格的卫生措施，包括定期 PCR 检测。
To evaluate the restart of the German Bundesliga (football (soccer)) during the COVID-19 pandemic from a medical perspective. Participants were male professional football players from the two highest German leagues and the officials working closely with them. Our report covers nine match days spread over 9 weeks (May to July 2020). Daily symptom monitoring, PCR testing for SARS-CoV-2 RNA twice weekly, and antibody tests (on two occasions—early during the phase in May 2020 and in the week of the last match) were conducted. Target variables were: (1) onset of typical COVID-19 symptoms, (2) positive PCR results, and (3) IgG seroconversion against SARS-CoV-2. All detected seroconversions were controlled by neutralisation tests. Suspicious symptoms were reported for one player; an immediate additional PCR test as well as all subsequent diagnostic and antibody tests proved negative for coronavirus. Of 1702 regularly tested individuals (1079 players, 623 officials members), 8 players and 4 officials tested positive during one of the first rounds of PCR testing prior to the onset of team training, 2 players during the third round. No further positive results occurred during the remainder of the season. 694 players and 291 officials provided two serum samples for antibody testing. Nine players converted from negative/borderline to positive (without symptoms); two players who initially tested positive tested negative at the end of the season. 22 players remained seropositive throughout the season. None of the seroconversions was confirmed in the neutralisation test. Professional football training and matches can be carried out safely during the COVID-19 pandemic. This requires strict hygiene measures including regular PCR testing.
