洗手和保持社交距离是世界卫生组织 (WHO) 建议的避免感染 COVID-19 的主要措施。不幸的是，这些测量结果并不能防止吸入感染者呼出的小液滴而引起的感染，这些小液滴可以在空气中传播数米或数十米的距离并携带病毒内容。科学解释了这种传播的机制，并且有证据表明这是室内环境中的重要感染途径。尽管如此，没有任何国家或当局在其法规中考虑通过空气传播 COVID-19 来防止感染在室内传播。因此，极其重要的是，国家当局承认病毒通过空气传播的现实，并建议采取适当的控制措施，防止 SARS-CoV-2 病毒进一步传播，特别是通过通风去除室内空气中携带病毒的飞沫。
Hand washing and maintaining social distance are the main measures recommended by the World Health Organization (WHO) to avoid contracting COVID-19. Unfortunately, these measured do not prevent infection by inhalation of small droplets exhaled by an infected person that can travel distance of meters or tens of meters in the air and carry their viral content. Science explains the mechanisms of such transport and there is evidence that this is a significant route of infection in indoor environments. Despite this, no countries or authorities consider airborne spread of COVID-19 in their regulations to prevent infections transmission indoors. It is therefore extremely important, that the national authorities acknowledge the reality that the virus spreads through air, and recommend that adequate control measures be implemented to prevent further spread of the SARS-CoV-2 virus, in particularly removal of the virus-laden droplets from indoor air by ventilation.
