Abstract Within a time span of only a few months, the SARS-CoV-2 virus has managed to spread across the world. This virus can spread by close contact, which includes large droplet spray and inhalation of microscopic droplets, and by indirect contact via contaminated objects. While in most countries, supermarkets have remained open, due to the COVID-19 pandemic, authorities have ordered many other shops, restaurants, bars, music theaters and indoor sports centers to be closed. As part of COVID-19 (semi)lock-down exit strategies, many government authorities are now (May 2020) allowing a gradual re-opening, where sometimes indoor sport centers are last in line to be permitted to re-open. This technical note discusses the challenges in re-opening these facilities and the measures already suggested by some to tackle these challenges. It also elaborates three potential additional measures and based on these additional measures, it suggests the concept of a certificate of equivalence that could allow indoor sports centers with such a certificate to re-open more rapidly. It also attempts to stimulate increased preparedness of indoor sports centers for potential next waves of SARS-CoV-2 as well as future pandemics. It is concluded that fighting situations such as the COVID-19 pandemic and limiting economic damage requires increased collaboration and research by virologists, epidemiologists, microbiologists, aerosol scientists, building physicists, building services engineers and sports scientists.

在 COVID-19 大流行期间，能否根据等效证书允许室内体育中心重新开放？

摘要 在短短几个月的时间里，SARS-CoV-2 病毒已成功传播到世界各地。这种病毒可以通过密切接触传播，包括大液滴喷雾和吸入微小飞沫，以及通过受污染的物体间接接触。虽然在大多数国家，超市仍然营业，但由于 COVID-19 大流行，当局已下令关闭许多其他商店、餐馆、酒吧、音乐剧院和室内运动中心。作为 COVID-19（半）锁定退出策略的一部分，许多政府当局现在（2020 年 5 月）允许逐步重新开放，有时室内运动中心排在最后一位被允许重新开放。本技术说明讨论了重新开放这些设施所面临的挑战以及一些人已经提出的应对这些挑战的措施。它还阐述了三项潜在的额外措施，并基于这些额外措施，提出了等效证书的概念，可以让拥有此类证书的室内运动中心更快地重新开放。它还试图刺激室内体育中心加强对潜在的下一波 SARS-CoV-2 以及未来大流行的准备。结论是，应对 COVID-19 大流行等情况和限制经济损失需要病毒学家、流行病学家、微生物学家、气溶胶科学家、建筑物理学家、建筑服务工程师和体育科学家加强合作和研究。它提出了等效证书的概念，可以让拥有此类证书的室内运动中心更快地重新开放。它还试图刺激室内体育中心加强对潜在的下一波 SARS-CoV-2 以及未来大流行的准备。结论是，应对 COVID-19 大流行等情况和限制经济损失需要病毒学家、流行病学家、微生物学家、气溶胶科学家、建筑物理学家、建筑服务工程师和体育科学家加强合作和研究。它提出了等效证书的概念，可以让拥有此类证书的室内运动中心更快地重新开放。它还试图刺激室内体育中心加强对潜在的下一波 SARS-CoV-2 以及未来大流行的准备。结论是，应对 COVID-19 大流行等情况和限制经济损失需要病毒学家、流行病学家、微生物学家、气溶胶科学家、建筑物理学家、建筑服务工程师和体育科学家加强合作和研究。
