At the end of December 2019, the rapid spread of the COVID-19 (SARS-CoV-2) disease and, subsequently, deaths around the world, lead to the declaration of the pandemic situation in the world. At the beginning of the epidemic, much attention is paid to person-to-person transmission, disinfection of virus-contaminated surfaces, and social distancing. However, there is much debate about the routes of disease transmission, including airborne transmission, so it is important to elucidate the exact route of transmission of the COVID-19 disease. To this end, the first systematic review study was conducted to comprehensively search all databases to collect studies on airborne transmission of SARS-CoV-2 in indoor air environments. In total, 14 relevant and eligible studies were included. Based on the findings, there is a great possibility of airborne transmission of SARS-CoV-2 in indoor air environments. Therefore, some procedures are presented such as improving ventilation, especially in hospitals and crowded places, and observing the interpersonal distance of more than 2 m so that experts in indoor air quality consider them to improve the indoor air environments. Finally, in addition to the recommendations of the centers and official authorities such as hand washing and observing social distancing, the route of air transmission should also be considered to further protect health personnel, patients in hospitals, and the public in other Public Buildings.
2019 年 12 月底，COVID-19（SARS-CoV-2）疾病的迅速传播以及随后在全球范围内的死亡，导致世界范围内宣布大流行情况。在疫情开始时，人们非常关注人与人之间的传播、病毒污染表面的消毒和社交距离。然而，关于疾病传播途径存在很多争议，包括空气传播，因此阐明 COVID-19 疾病的确切传播途径非常重要。为此，进行了第一项系统综述研究，全面搜索所有数据库以收集有关 SARS-CoV-2 在室内空气环境中空气传播的研究。共有 14 项相关且合格的研究被纳入。基于研究结果，SARS-CoV-2 在室内空气环境中具有很大的空气传播可能性。因此，提出了一些程序，例如改善通风，特别是在医院和拥挤场所，并保持 2 米以上的人际距离，以便室内空气质量专家考虑这些程序以改善室内空气环境。最后，除了洗手和保持社交距离等中心和官方当局的建议外，还应考虑空气传播途径，以进一步保护医院的卫生人员、患者和其他公共建筑中的公众。
